Brainy is a lifesaver!!!!!

Brainly is a lifesaver. It is SOOOO helpful and my grades definitely wouldn’t be where they are now if it weren’t for Brainly. I struggle a bit in certain subjects and so if I need help I just go to Brainly and ask a question or search for a question others have asked and read explanations. You see, Brainly doesn’t just give you the answer, they give you a thorough step-by-step explanation that really helps you understand how to get to the correct answer. Helps me every time. I have paid $0 and I can still get so much homework assistance. I also really love Brainly AI because all you do is ask/scan the question and the AI gives you a PERFECT step-by-step explanation. I’ve tried other online [math] calculators that also give step-by-step explanations, but sometimes I don’t understand and just ask Brainly AI and I understand it much better. The best part is that you can use their AI for free :) I also really enjoy answering other people’s questions and I like how Brainly incorporates points and badges into the app because it keeps you motivated to ask questions and help other people as well. Great work! ❤️📚📎✏️

Brainily plus subscription

I have been using the tutors to help me with some challenging questions for my math homework. Many have been very helpful but you’re only able to ask 20 questions a month. I have used 12/20 mostly because the tutors take me in then say they can’t solve the question and end the session. Because of this it has been using up the questions I can ask for this month. And when you loose connection it gets rid of all the tutors work and you have to ask a new tutor. Its really upsetting when you have waited to find out how to solve the question your struggling on for 10 or minutes to see oh you lost connection go find a new tutor. It happened to me once and all the other tutors gave me the wrong answer or said they didn’t know how to do it. One tutor was convinced what they got was the right answer but my teacher gives us the correct answers so we can check our work. I would have made a comment on it but then it said I lost connection. Which is really weird because I have really good wifi and it doesn’t say or do this on other apps. If this happens I wish there was a reconnect option. Just know when you sign up for brainly plus there is a chance the tutors won’t give you the correct answer. They are real people and won’t know how to do everything and can make minor mistakes within the problems. Just make sure you go through and check everything and that it makes sense to you before you end the session.

Ads loading forever and not showing up at all...

The app it’s self is really good and very helpful and I appreciate it very much but, Recently for the past 3 days whenever I’ve went into the app and had to watch an ad as usual, it would load for very a long time and never show up in the end no matter how long I waited. I even tried many things to see what the problem was. My connection was fine and I’ve tried to refresh, turn off or shut off my phone, logging in out logging back in, deleting the app and re-installing, and offloading the app. But with all the efforts I put in to make it work it never did. So I decided to go on the website instead and it worked perfectly fine the ads did show up and let me play them. So the problem seemed to be the app it’s self, but the only thing that is inconvenient about going to the website instead of the app, is it only gives me a limited amount of ads I can watch to get answers in a day. I’m not sure if I’m The only one with this problem but I believe since a couple days have passed this seem to be a really worrisome for me and difficult since I really like the app in general. So therefore, I would like to see and know if there’s anything I’m doing wrong or something that I need to do to make it work. Please and thank you for your value time.

Top 20 Current Global Issues We Must Address

What are the most pressing issues in the world today? What will demand the most attention in the next 5, 10, and 20+ years? In this article, which frequently refers to the World Economic Forum’s 17th Edition of the Global Risks Report, we’ll highlight 20 current global issues we must address, including issues related to climate change, COVID-19, social rights, and more. While it’s hardly a comprehensive discussion, it’s a solid introduction to the kinds of concerns facing our world today.

#1. Poverty

In fall 2022, the World Bank will update the International Poverty Line from $1.90 to $2.15. This means anyone living on less than $2.15 is in “extreme poverty.” Why the change? Increases in the costs of food, clothing, and shelter between 2011-2017 make the “real value of $2.15 in 2017 prices equal to $1.90 in 2011 prices. As for the World Bank’s goal to reduce extreme poverty to 3% or less by 2030, the pandemic has made it even harder. Extreme poverty isn’t the only poverty we have to contend with. 62% of the global population lives on less than $10/day. While there’s been progress over the years, the end of poverty is still far off.

#2. Climate change

The IPCC released its sixth report in 2022. In its summary for policy-makers, the report’s authors outlined a series of near-term, mid-term, and long-term risks. If global warming reaches 1.5°C in the near term (2021-2040), it would cause “unavoidable increases in multiple climate hazards,” as well as “multiple risks to ecosystems and humans.” In the long term, climate change will present major health issues, premature deaths, risks to cities and settlements , and other dangers. Mitigation is desperately needed – and fast. Because of climate change ’s connection to other issues on this list, it’s one of the most serious challenges facing humanity.

#3. Food insecurity

According to the 2022 Global Report on Food Crises , which is produced by the Global Network against Food Crises, the number of people in crisis or worse is the highest it’s been in the six years since the report has existed. Close to 193 million people were experiencing acute food insecurity in 2021, which is an increase of almost 40 million since 2020. This represents a staggering 80% increase since 2016. Causes include “economic shocks,” like an increase in global food prices. Domestic food price inflation in low-income countries also rose a lot. “Weather-related disasters” are also a big driver. For 15.7 million people in 15 countries, it was the primary driver of acute food insecurity.

#4. Refugee rights

According to UNHCR, the war in Ukraine sparked the fastest-growing refugee crisis since WWII. Almost 6 million (as of May 10, 2022) people have fled. The UNCHR’s Refugee Brief , which compiles the week’s biggest refugee stories, has recently described situations in places like Somalia, where thousands of people were displaced due to severe drought. Between January and mid-April, more than 36,000 refugees from Nigeria, Mali, and Burkina Faso arrived in Niger. These are only a few examples of the refugee crises, which endangers already marginalized groups – like women and children – and puts them at an increased risk of trafficking , violence, and death.

#5. COVID-19

The WHO declared COVID-19 a pandemic in March 2022. It will continue to be a major issue for the world. The WEF’s Global Risks Report 2022 discusses COVID’s effects at length , including major economic recovery disparities and social erosion. According to a January 2022 article from NPR , there are also issues with vaccinations as many countries continue to have trouble getting doses. Distribution, vaccine hesitancy, healthcare systems, and other problems also factor into low vaccination rates. While we may never know the exact impact, the WHO estimates that between 1 January 2020 and 31 December 2021, there were around 14.9 million excess deaths linked to COVID-19.

#6. Future pandemic preparation and response

COVID-19 taught the world the importance of prepardeness. In a Harvard blog , Dr. Tedros Adhanom Ghebreyesus, director-general of the WHO, outlined the lessons the world should take to heart. The first: science has to guide policy. The politicization of the pandemic led to a lot of unnecessary damage. Another lesson is that science must pair with equity or it can actually make inequalities worse. This is obvious when looking at how low-income countries struggled to get the vaccines while wealthier countries stocked up. More resilient healthcare systems are also a must, as well as more coherent, global plans on how to respond. The world must also invest in research on contagious diseases, zoonotic diseases, the effectiveness of outbreak responses, and more.

#7. Healthcare

The healthcare industry has experienced major shifts due to the COVID-19 pandemic. According to the World Economic Forum, there’s been new investments and innovations, especially from the technology and telehealth sectors. In 2021, $44 billion was spent on health innovation. The world will be seeing the effects of these innovations for years to come, though equity will no doubt be a major issue. In places like the United States, the pandemic also reaffirmed how broken healthcare systems can be. In an MIT News blog , Andrea Campbell, a professor of political science, says the pandemic revealed a “dire need” for investments in public-health infrastructure, as well as a need to expand healthcare access and insurance coverage.

#8. Mental health

Globally, almost 1 billion people have some form of mental disorder. The pandemic made the world’s mental health worse. According to a scientific brief from the WHO , there’s been a 25% increase in anxiety and depression worldwide. Causes include social isolation, fear of sickness, grief, and financial anxieties. Health workers were also severely impacted, as well as young women and girls. The brief also highlights how the pandemic disrupted many mental health services, including services for substance abuse. Countries need to ensure access to mental health services as part of their COVID-19 recovery plans and beyond. It’s an economic decision, as well. The Lancet states that anxiety and depression alone cost the global economy around $1 trillion a year.

#9. Disability rights

According to the WHO , over 1 billion people have some form of disability. Half can’t afford healthcare. They’re also more likely to live in poverty than those without a disability, have poorer health outcomes, and have less access to work and education opportunities. Human Rights Watch lists other discriminations disabled people face, such as an increased risk of violence. There’s been progress regarding disability rights, but many countries lack strong protections. The world still has a long way to go to ensure equality for those with disabilities.

#10. LGBTQ+ rights

Members of the LGBTQ+ community face discrimination in many forms. According to Amnesty International , discrimination can target sexual orientation, gender identity, gender expression, and sex characteristics. Even in more progressive countries like the United States, people face violence and discrimination. According to the Human Rights Campaign, more than 300 anti-LGBTQ+ bills were proposed in 2022. At least a dozen states are considering legislation that forbids schools from discussing or using a curriculum that covers sexual orientation and gender identity. Considering the United States’ influence in the world, this attack on LGBTQ+ rights will likely have consequences that need to be addressed.

#11. Reproductive justice

Reproductive justice – which encompasses more than just abortion rights – is threatened by legislation, lack of funding, lack of education, and restricted healthcare access. In most places, wealth is a big determinant of whether a person can access reproductive services. It’s better in some places than others, but as we’ve seen with other issues on this list, even “progressive” countries like the United States are experiencing major shifts. In June 2022, the Supreme Court is expected to overrule Roe v. Wade , a milestone court case that protected a pregnant woman’s right to abortion. The impact would be immediate and will likely influence other countries.

#12. Children’s rights

Children are a very vulnerable group. In 2019, around 5.2 million children under five from mostly preventable and treatable causes. 2.4 million were newborns under 28 days old. Leading causes include preterm birth complications, pneumonia, and malaria. According to UNICEF, the climate crisis also represents a severe threat to kids. Around 1 billion kids live in “extremely high-risk countries” that are hit by the worst effects of climate change. 920 kids have trouble accessing clean water and 600 million are exposed to vector-borne diseases like malaria. Child labor also remains an issue. At the beginning of 2020, around 160 million were forced into labor while COVID-19 put 9 million more kids at risk. That’s almost 1 in 10 children globally. Almost half are in dangerous environments. As is often the case, the other issues on this list – climate change, poverty, COVID, gender equality, etc – factor into children’s rights.

#13. Gender equality

Global gender equality has gradually improved over the years, but data from the 2021 Global Gender Report shows that the end of the global gender gap is still 135 years away. The pandemic played a huge role in reversing positive trends as women were hit harder financially. According to Oxfam , women experienced a 5% job loss while men experienced 3.9%. That means women lost about $800 million in 2020. This is a low estimate since it doesn’t count the informal economy, which includes millions of women. Women are also more likely to live in poverty, more affected by gender-based violence, and more affected by climate change.

#14. Cybersecurity

The WEF’s Global Risks Report 2022 (page 9) listed cybersecurity vulnerabilities as a concern. The reason is rapid digitalization, which was triggered in part by COVID-19. Many “advanced economies” are now at a higher risk for cyberattacks. GRPS respondents identified cybersecurity failure as a critical short-term risk. In 2020, malware and ransomware attacks went up by 358% and 435%. There are a few reasons for this, including better (and easier) attack methods and poor governance. Cyberattacks have a swath of serious consequences and erode public trust. As countries become more dependent on digitalization, their cybersecurity needs to keep up.

#15. Disinformation

Rapid digitalization comes with many issues, including the lightning-fast spread of disinformation. The WEF report describes deepfakes, an accessible AI technology, and its potential to sway elections and other political outcomes. Disinformation doesn’t need to be sophisticated to be successful, however. Through social media posts and videos, twelve anti-vax activists were responsible for almost ⅔ of all anti-vaccine content on platforms like Facebook and Twitter. Their content flooded the internet with the type of harmful, fear-mongering disinformation that played a significant role in vaccine hesitancy and political radicalization. Because disinformation travels faster online than the truth, it’s a global issue that should be addressed.

#16. Freedom of the press

According to the Varieties of Democracy Institute (as reported in The Economist ), about 85% of people live in a country where press freedom has gone down in the past 5 years. After peaking at .65 in the early 2000s and 2011, the global average dropped to .49 in 2021. Major countries like China, India, Russia, Brazil, and Turkey saw significant declines. Journalists and news organizations face threats like violence, imprisonment, lack of funding, and coordinated online attacks and harassment. A free press is essential to a functioning democracy. Without press freedom, all human rights are at risk.

Learn more about freedom of expression: Human Rights for Open Societies (Utrecht University)

#17. Debt crises

In the WEF Global Risks Report (page 7), respondents named debt crises as one of the most pressing issues over the next decade, though respondents believe they will become most serious in just 3-5 years. COVID-19 is a big reason why. Government stimulus was necessary, but many countries are now left with debt burdens. For corporate and public finances in large economies, debt burdens can lead to defaults, bankruptcies, insolvency, and more. This is a far-reaching issue as it affects budgets for areas like healthcare and green energy.

#18. Corruption

Corruption encompasses a host of actions such as bribery, election manipulation, fraud, and state capture. The World Bank Group names corruption as a barrier to ending extreme poverty and “boosting shared prosperity” for the poorest populations. When it comes to addressing poverty, climate change, healthcare, gender equality, and more, corruption gets in the way. Because corruption is a global problem, global solutions are necessary. Reform, better accountability systems, and open processes will all help.

Learn more about tackling corruption: What is Corruption: Anti-Corruption and Compliance (University of Pennsylvania)

#19. Authoritarianism

According to Freedom House, global democracy is eroding. That includes countries with long-established democracies. In their 2022 report, the organization reveals that global freedom has been declining for the past 16 years. 60 countries faced declines in the last year. Only 25 saw improvements. Only 20% of the global population lives in Free countries. China, Russia, and other authoritarian countries have gained more power in the international system, while countries with established democracies – like the United States – are losing their freedoms. What can be done? Freedom House says success “requires a bold, sustained response that establishes support for democracy and countering authoritarianism.” Governments and citizens engage and stand for democracy.

#20. Global cooperation

Addressing the issues in this article is not an easy task. True progress is only possible through global cooperation, a fact which is woven through the WEF report. Everything from addressing cybersecurity threats to humanitarian emergencies to protecting democracy depends on strong cooperation between countries. As the report says in its preface: “Restoring trust and fostering cooperation within and between countries will be crucial to addressing these challenges and preventing the world from drifting further apart.” The challenges threatening global cooperation are just as clear as the need, however, which makes it one of the most serious issues of the day.

  • The failure of governments to find multilateral solutions to global problems means that significant challenges are being neglected.
  • Instead governments can begin to solve global issues by taking a pragmatic, local approach to find innovative solutions.
  • We've tested this approach by providing solutions to three challenges that are fundamental to the development of countries and their citizens.

Rising polarization, nationalism, corruption, lack of political will and insular political agendas have combined to reduce the viability of many multilateral solutions to global problems. Just look at climate change to see the obstacles standing in the way of countries all pulling in the same direction.

Despite these barriers governments can’t avoid these large problems. Instead, they can tackle even the thorniest of issues by thinking big, acting fast, but starting small. In practice, this means viewing a global concern through a local lens; addressing it with a pragmatic but innovative solution, and as positive results emerge, scaling it so its reach broadens among wider regions and groups of people.

Have you read?

World hunger surged in 2020, with 1 in 10 people on earth undernourished, if you want to make progress on all the major global challenges, start with water, this is how digital literacy can transform education.

We applied this approach to three challenges that are fundamental to the development of countries and their citizens: the need for food and clean water, and bridging the digital divide.

The three critical global imperatives we identified would be perfect vehicles for these targeted resources. Moreover, the solutions come at minimal political cost, eschew multilateralism for simplicity, and deliver economic, social and political benefits that outweigh their price.

1. Enhance access to nutrition from ages 0-3 and promote healthy diets for all ages

Inadequate nutrition during the first 1,000 days of life can result in irreversible stunting of growth, cognitive ability disorders, and decreased productive potential as adults. Governments can address this problem through subsidies, nutritional surveillance and education.

  • Subsidize biofortified food. Governments should provide support payments for people under the poverty line in remote and rural areas to purchase biofortified food. These subsidies would encourage local farmers to add vitamins and minerals to their crops since they would have a growing and reliable market in which to sell their products.
  • Implement systems that monitor and forecast nutrition risk. Governments can track nutritional deficiencies in their populations with programmes like the Nutrition Early Warning System (NEWS), designed to tackle malnutrition in sub-Saharan Africa. NEWS algorithms analyze data related to food availability and diets in the region to identify patterns predictive of impending nutritional threats.
  • Mainstream maternal and child nutrition in health systems. Governments need to ensure that primary health care facilities providing routine maternal and child development services integrate child nutrition and feeding practices into their interactions with patients.

Two billion people in the world currently suffer from malnutrition and according to some estimates, we need 60% more food to feed the global population by 2050. Yet the agricultural sector is ill-equipped to meet this demand: 700 million of its workers currently live in poverty, and it is already responsible for 70% of the world’s water consumption and 30% of global greenhouse gas emissions.

New technologies could help our food systems become more sustainable and efficient, but unfortunately the agricultural sector has fallen behind other sectors in terms of technology adoption.

Launched in 2018, the Forum’s Innovation with a Purpose Platform is a large-scale partnership that facilitates the adoption of new technologies and other innovations to transform the way we produce, distribute and consume our food.

With research, increasing investments in new agriculture technologies and the integration of local and regional initiatives aimed at enhancing food security, the platform is working with over 50 partner institutions and 1,000 leaders around the world to leverage emerging technologies to make our food systems more sustainable, inclusive and efficient.

2. Clean up and improve management of water supplies

By 2025, water shortages and pollution and an increase in deadly but preventable water-related diseases will plague two-thirds of the world’s population. We recommend three approaches involving natural systems, digital systems, and systems management to meet water needs.

solve the world problems brainly

  • Develop innovative sanitation systems. Rather than default to costly and wasteful sewage systems, governments should also adopt decentralized technologies for water containment, treatment, safe disposal and recycling. One promising approach is to reuse local wastewater for drinking, organic fertilizer and insect-derived animal feed.
  • Use green infrastructure. Governments should complement “grey” water management infrastructure –human-made water and wastewater treatment plants, pipelines and reservoirs – with green infrastructure, such as forests, wetlands, and mangroves that can provide water purification; natural storage, boosting water supplies; and flood management. In 2014, São Paulo, Brazil, nearly ran out of water amid the region’s worst drought. Today, local forest restoration has reduced water pollution and increased dry season water flow, thereby boosting annual water supply at a significantly lower cost than traditional water management.
  • Design a data-driven way to manage water resources using advanced technology. Nearly 32m 3 billion of water are lost annually due to poor water infrastructure. Internet of Things (IoT) and artificial intelligence (AI) systems can detect water leakage and quality issues through analysis of water resources, while precision agriculture, which calculates crop water levels and requirements, can reduce outsized farm water consumption by as much as 75%.

3. Guarantee access to digital information and digital literacy

The COVID-19 pandemic has exposed digital socio-economic schisms. In some form, remote schooling, working and socializing will remain more important than ever, and technological competence is essential. What can governments do quickly and relatively inexpensively?

  • Ensure universal connections to digital infrastructure. In developing countries, governments can provide universal, reliable, and stable internet connections to rural or underserved areas by mandating that telecom operators speed up the construction of broadband networks.
  • Bridge the material access gap. Smartphones are ubiquitous. By enhancing productivity, political participation and self-improvement, smartphones pale against PCs, laptops and tablets, which are out of reach to many poor or less educated people. Governments can bridge this affordability gap through loans and direct provision of devices. This is already happening in response to distance learning during the COVID-19 pandemic. In India, state governments have distributed tablets with e-learning material to students, while England and Germany have subsidized the purchase of laptops and electronic devices for less wealthy students so they can participate in online learning opportunities.
  • Promote digital literacy with education. Digital citizens courses should be mandatory to equip all residents with essential technological knowledge and skills. In many countries schools provide formal technology lessons, but governments need to offer public online courses that target more vulnerable segments of the digital population such as senior citizens and the uneducated.

Governments can still achieve tangible success with these large issues by thinking big and starting small. Out of that, as scaling becomes possible, the big problems that seem so intractable today will be brought down to size.

Climate Change

The 5 greatest challenges to fighting climate change

Kara Baskin

Dec 27, 2019

Climate change: Most of the world agrees it’s a danger, but how do we conquer it? What’s holding us back? Christopher Knittel, professor of applied economics at the MIT Sloan School of Management, laid out five of the biggest challenges in a recent interview.

CO2 is a global pollutant that can’t be locally contained

“The first key feature of climate change that puts it at odds with past environmental issues is that it’s a global pollutant, rather than a local pollutant. [Whether] I release a ton of CO2 in Cambridge, Massachusetts, or in London, it does the same damage to the globe,” Knittel said. “Contrast that with local pollutants, where if I release a ton of sulfur dioxide or nitrogen oxide in Cambridge, the majority of the damage stays near Cambridge.”

Thus, CO2 is far harder to manage and regulate.

For now, climate change is still hypothetical

The damage caused by most climate change pollutants will happen in the future. Which means most of us won’t truly be affected by climate change — it’s a hypothetical scenario conveyed in charts and graphs. While we’d like politicians and voters to be moved by altruism, this isn’t always the case. In general, policymakers have little incentive to act.

“People [who stand to be] most harmed by climate change aren’t even born yet. Going back to the policymaker’s perspective, she has much less of an incentive to reduce greenhouse gas emissions because those reductions are going to benefit voters in the future and not her current voters,” Knittel said.

There’s no direct link to a smoking gun

Despite the global threat from climate-altering pollutants, it’s hard for scientists to link them to a specific environmental disaster, Knittel said. Without a definitive culprit, it’s easier for skeptics to ignore or explain away climate change effects.

Developing countries contribute to a large share of pollution

Simply put, this isn’t their top priority.

“We’re asking very poor countries that are worried about where their next meal is coming from, or whether they can send their kids to school, to incur costs to reduce greenhouse gas emissions to benefit the world. And that’s a tough ask for a policymaker inside of a developing country,” he said.

Modern living is part of the problem

It’s a tough pill to swallow, but modern conveniences like electricity, transportation, and air conditioning contribute to climate change, and remedies potentially involve significant sacrifice and lifestyle change.

“Although we’ve seen great strides in reductions in solar costs and batteries for electric vehicles, these are still expensive alternatives. There is no free lunch when it comes to overcoming climate change,” Knittel warned.

Writing in the Los Angeles Times  recently, Knittel said, “If an evil genius had set out to design the perfect environmental crisis … those five factors would have made climate change a brilliant choice. But we didn’t need an evil genius. We stumbled into it on our own.”

Top 10 world problems and their solutions

Top 10 world problems and their solutions

The last decade has been marked by significant progress in various fields such as science, medicine, and technology but, at the same time, the number of problems in today’s society has steadily grown. In 2020 and 2021, undoubtedly some of the most uncertain and difficult years of the last decade, the biggest problems in the world were the COVID-19 pandemic and poverty. However, the years that followed continued to be somewhat complex and certainly no less easy.

In 2022 – 2023, the war in Ukraine, the Israel – Hamas conflict , the energy crisis and hyperinflation caused multiple economic shocks and stagnation across the continents.

As a platform to address global issues that cannot be resolved by any single country, the United Nations organization is spearheading humanity’s struggle to survive. Its most visible efforts concern resolving conflicts and undertaking peacekeeping activities. Below is a list of the world’s greatest according to the UN.

Climate Change

There is no economy or individual that is unaffected by climate change. By 2050, this problem could force 216 million people to relocate within their own nations. The changes in weather may worsen water stress and reduce crop output, particularly in the most food-insecure areas of the world.

One of the major problems on our planet is linked to global temperatures that are continually rising. By 2100, studies show that there is a 50% likelihood of facing global warming that is higher than 3.5 degrees Celsius and a 10% probability of witnessing warming higher than 4.7 degrees Celsius relative to temperatures registered between 1850 and 1900. This would result in more severe shifts in weather patterns, food and resource shortages, and the more rapid spread of diseases.

At COP28 in Dubai, held at the end of 2023, the World Bank unveiled ambitious plans to boost climate funding, improve initiatives for carbon markets, and much more.

Possible solutions:

A reduction in greenhouse gas emissions and increased awareness of the necessity to turn green are among the solutions that can make a significant difference. In addition, strategies to cut carbon emissions and opting for replanting are among the effective ways to address climate change.

Wars and military conflicts

Maintaining peace and security is crucial to preventing poverty and high numbers of refugees and asylum seekers. With an increasing number of territories becoming conflict zones, the number of poor and displaced women and children is on rise, causing the spread of diseases and a halt to economic progress.

Preventative diplomacy and demilitarization are the two key tactics for avoiding conflicts. Preventive diplomacy is defined as those actions undertaken to avoid conflicts from forming or worsening. It can also help to limit the spread of existing hostilities. Mediation, conciliation, or negotiation are all options to tackle this world issue.

Today, among the greatest world issues, wars and conflicts are at the top of the list. 2022 and 2023 were marked by a number of conflicts that led to many casualties and displaced people. The conflicts in Ukraine and Palestine in particular have led to a massive number of people fleeing or attempting to flee their countries in search of shelter.

Individuals with disabilities and the elderly are the most vulnerable because they may not be able to escape high-risk regions.

As of May 2023, there were around 5.1 million internally displaced persons in Ukraine and the number of documented refugees from Ukraine was over 6.2 million worldwide. Around 90% of those escaping the crisis were women and children.

In Gaza, there are approximately 1.4 million internally displaced people with around 690,000 being housed in 150 shelters run by the UN agency for Palestine refugees.

Refugee statistics:

  • In mid-2023, according to the UN , there were 110 million forcibly displaced people in the world
  • 43.3 million (around 40%) of these were children
  • 1.9 million children were born as refugees
  • 36.4 million (over 30%) of all displaced people were refugees
  • 6.1 million were asylum-seekers
  • 4.4 million stateless people reside in 97 countries although it has been estimated that the true figure is much higher
  • Over 50% of refugees come from just three countries: the Syrian Arab Republic, Afghanistan, and Ukraine.

Water contamination

There is no life without water – apparently a simple truth but one that people seem to overlook. Poor management and irrational use forces communities to migrate in search of drinking water. Industries are polluting underground water and this issue is growing massively.

  • Due to pollution, poverty, and inadequate resource management, around 2.1 billion people lack access to safe drinking water
  • Agriculture is responsible for 70% of global water loss
  • Annually, 297,000 children under the age of five die from diarrheal infections caused by poor sanitation, hygiene, or contaminated drinking water
  • 80% of wastewater is discharged into the environment without being processed or reused

Possible solutions to the water pollution issue:

The most efficient technique to reduce water pollution is to treat water (filtration, disinfection, etc.) before it reaches the waterway system. Clearing wastewater of pollutants can be performed via biological, physical, and chemical operations.

Human rights violation

Human rights are universal, regardless of race, gender, ethnicity, religion, or any other status but what if this only happens on paper?

Indeed, the problems in today’s society are linked with the constant violation of human rights – gender inequality, human trafficking, the lack of freedom of speech – all of these can be witnessed in the 21st century in every country, even in developed nations.

Gender Equality

50% of the world’s population are women and girls. Gender equality is not only a crucial human right , it is also necessary for a peaceful society, the full development of human potential, and long-term evolution.

Possible solutions to gender inequality:

  • Speak up for what you believe in
  • Pay attention to what others have to say
  • Defend yourself from discrimination
  • Raise public awareness of a problem
  • Get the media to talk about it
  • Demonstrate to those in positions of power that they are being watched

Global health issues

There is no comprehensive list of the top global health challenges because this field is dynamic and ever-evolving. In addition, new threats and hazards related to global health are constantly emerging as seen by the monkeypox outbreak that occurred in 2023. On the other hand, certain global health problems are long-term and may be on the list forever including cancer, air pollution, and tuberculosis.

Major health problems in the world include:

  • Communicable diseases

Influenza outbreaks and COVID-19 are examples of pandemics that highlight our susceptibility to widespread infections, many of which begin in animals. Anxiety and fear are common reactions to pandemics. Other worrisome infectious diseases worth attention are HIV/AIDS, malaria, and Ebola which have remained deadly for decades.

  • Environmental factors

Air pollution and climate change have a serious impact on our health. Hurricanes, floods and droughts make disease transmission easier among large populations of people.

  • Inequalities and poor healthcare access

Poor access to healthcare, increased infant mortality rates, mainly in low-income nations, and income inequality around the world make it virtually impossible for many families to afford healthcare.

  • Political aspects

People become increasingly exposed to diseases as wars within or between countries damage essential infrastructure. As a result, they look for ways to escape the harmful situations that jeopardize their safety but diseases can spread swiftly when people migrate.

  • Mental health

A major contributor to disability is depression, and among those aged 15 to 29, suicide caused by depression is the main cause of mortality. Individuals suffering from serious mental health issues frequently encounter stigma, discrimination, and infringements of their human rights which can lead to earlier death. In less severe cases, mental health conditions can impact participation in social activities, close interpersonal connections, and academic or professional performance.

  • Noncommunicable diseases (NDCs)

Cancer, heart disease, and diabetes are just a few examples of noncommunicable diseases (NCDs). The risk factors for NCDs include the use of tobacco products and alcohol, obesity, a poor or unbalanced diet, and lack of exercise. Although these global health concerns are present everywhere and are responsible for almost 3 out of every 4 deaths worldwide, low- and middle-income nations make up 77% of NCD deaths .

Possible solutions to global health issues:

  • Empower marginalized populations
  • Encourage physicians to work in rural regions
  • Implement policies that eliminate obstacles and improve access to healthcare
  • Promote health breakthroughs (improve research, increase funding)
  • Education can help people recognize and improve lifestyle variables such as poor diets, obesity, cigarette use, and alcohol intake which can lead to NCDs.
  • Veterinary medicine can enhance global health since diseases originating from livestock play an important role in the spreading of diseases.

Global poverty

Although there has been a decline in extreme poverty in middle-income nations, poverty in the world’s poorest nations and those impacted by instability, wars, or violence remains higher than it was before COVID-19.

Currently, about 700 million people worldwide face extreme poverty, meaning that their daily income is less than the $2.15 poverty-line established by the World Bank . The majority of these individuals reside in sub-Saharan Africa. All in all, the places where it is most difficult to tackle extreme poverty are rural areas and regions impacted by conflicts. It’s worth mentioning that 50% of the people who live in extreme poverty are children.

Possible solutions to poverty:

  • End marginalization by ensuring equality and representation for all
  • Provide preventative education and treatment assistance during an epidemic
  • Offer recovery interventions during climate disasters
  • Help refugees and internally displaced people in terms of health, nutrition, and shelter
  • Improve education
  • Increase the level of food security and clean water access
  • Put an end to conflicts

Children’s poor access to healthcare, education and safety

Every child must benefit from the right to proper healthcare, access to education, and grow in safety, and every society benefits from increasing children’s life prospects. Despite this, millions of children worldwide face serious challenges linked with their birthplace, gender, or circumstances.

Over 72 million children around the world who are old enough to attend elementary school are not enrolled. Marginalization and poverty are two major social issues.

Possible solutions to protect children’s rights:

  • Encourage education for both children and adults in less developed countries
  • Provide clean water
  • Ensure basic healthcare
  • Tackle gender inequality
  • Improve childhood nutrition

Access to food and hunger

By 2030, it is less likely that the world will achieve Sustainable Development Goal 2: Zero Hunger, according to international agencies and media. The situation in countries that have faced food insecurity and where populations suffer from hunger has worsened further as a result of the health and socioeconomic effects of the COVID-19 pandemic.

Our planet houses over 8 billion people, and there is enough food to feed them all. Sadly, 828 million face hunger on a daily basis despite the quantity of available food.

According to the World Food Program , more than 40% of these people face severe hunger. At the same time, around 2.3 billion people lack proper access to food. Statistics also show that around 9 million people die each year from hunger-related factors – most of them being children aged 5 or younger.

  • In regions impacted by conflict, humanitarian, development, and peacebuilding initiatives should be rolled out quickly
  • The resilience of those who are more prone to economic hardship should be increased
  • To reduce the cost of nutritious foods, governments should intervene at various points in the food supply chain
  • Deal with poverty by focusing on interventions that help those suffering
  • Food environments should be reinforced. In addition, it is important to influence consumer behavior to encourage eating habits that are good for both people and the environment.
  • Experts believe that the immediate solution to the food crisis linked to the conflict in Ukraine could be monetary, mainly because of the rising food prices. If governments and donors are able to help people to pay for food, fewer will go hungry.

Massive migration movements impact all UN Member States , necessitating greater collaboration and responsibility-sharing.

The United Nations Member States endorsed the New York Declaration for Refugees and Migrants (A/RES/71/1) wherein they acknowledged that there is a need for a comprehensive strategy for migration. The New York Declaration recognizes the beneficial contributions of migrants to inclusive and sustainable development and pledges to defend their dignity, human rights, and basic freedoms, irrespective of their migration status.

Weapons accessibility

Multilateral disarmament and armaments restriction are the aims that have been important to the United Nations’ attempts to keep international peace since its inception.

The United Nations has placed a high priority on decreasing and ultimately eliminating nuclear weapons, abolishing chemical weapons, and reinforcing the ban on biological weapons, all of which pose the greatest dangers to humanity.

  • A number of multilateral treaties and procedures have been developed as a result of worldwide efforts to regulate, limit, or eliminate specific weapons, including:
  • Treaty on the Non-Proliferation of Nuclear Weapons – one of its goals is to stop nuclear weapons and weapons technology from spreading
  • Comprehensive Nuclear-Test-Ban Treaty – its goal is to prohibit nuclear weapons trial explosions, as well as any other nuclear explosions
  • Biological and Chemical Weapons Convention – forbids biological and toxin weapon manufacturing, procurement, transmission, storage, and use
  • Arms Trade Treaty – controls the international conventional armaments trade.

Although the top 10 global issues certainly help to establish what governments and ordinary people around the world should focus on, there are many other problems that everyone should be aware of, including the aging of the population, AIDS, and law and justice. Tackling at least some of these is possible but requires a lot of effort, patience and understanding.

Biotechnology – A Solution to Hunger?

About the author, kaiser jamil.

World hunger and food insecurity is a recurring problem in most parts of the developing world. Among the many potential biotechnologies that are available, and the different ways in which they can be applied, genetic modification (GM) of crops demands particular attention. Genetically modified crops possessing genes from different species, could possibly relieve global food shortages. Although initial excitement surrounded the use of GM crops -- that they will provide bigger and better harvests for farmers -- there are still questions about the benefits of such crops. In addition, the general public may not welcome the creation of "super plants" as a viable option in solving global hunger.

The environmental impact of GM crops is important with regard to creating food security in developing countries. Genetically modified crops can potentially fail to germinate; kill organisms other than pests that are beneficial to plants and reduce soil fertility; and potentially transfer insecticidal properties or virus resistance to wild relatives of the crop species.

A segment of the scientific community often proposes that export earnings from higher agricultural yields can contribute to reducing food insecurity and hunger in developing countries. However, there are many issues and challenges that beg the practicality of this proposal. A few crop varieties, specially created through biotechnology, can improve yields, but biotechnology alone cannot solve the problem of hunger in the developing world.

Nevertheless, the potential advantages that biotechnology can confer across a wide range of agricultural applications are in areas such as livestock management, storage of agricultural products and sustaining current crop yields, while reducing the use of fertilizers, herbicides and pesticides. The real challenge is whether we are smart enough to harness the benefits of biotechnological solutions. But what are these solutions?

Biotechnology offers a very promising alternative to synthetic foods and an improvement on conventional plant-breeding technologies. Combined with other advanced agricultural technologies, it offers an exciting and environmentally responsible way to meet consumer demand for sustainable agriculture. When the benefits of GM crops reach small and marginal farmers, more Green Revolutions may become a reality.

Combating Hunger and Malnutrition Malnutrition is the related term in medicine for hunger. The most recent estimate of the Food and Agriculture Organization says that 854 million people worldwide are undernourished. This is 12.6 per cent of 6.6 billion people in the world. Many of the 854 million that are undernourished, children being the most visible victims, live in developing countries. Undernutrition magnifies the impact of every disease, including measles and malaria.

One example tells us how biotechnology can contribute to combating global hunger and malnutrition.

Golden Rice Approximately 140 million children in low-income groups in 118 countries, especially in Africa and South-East Asia, are deficient in Vitamin A. This situation has compounded into a public health challenge. The World Health Organization reports that an estimated 250,000 to 500,000 Vitamin A-deficient children become blind every year, half of them dying within 12 months of losing their sight. Golden Rice, created by researchers in Germany and Switzerland, contains three new genes -- two from the daffodil and one from a bacterium -- that helps it to produce provitamin A. This rice is available as a possible option for mass distribution, in part due to the waiving of patent rights by biotechnology companies. This is just one among the hundreds of new biotech products, which point to the contributions of biotechnology to society.

Intellectual Property and Food Security There are concerns about a technological landscape controlled almost exclusively by the private sector and defined by patent protection. Patents allow large, private firms substantial control over plant genes, which has worrisome implications. If farmers have to purchase seeds during every sowing season, it affects their income and food security. Although biotech companies such as Monsanto and AstraZeneca have announced that they would not commercialize the so-called "Terminator" or seed-sterilization technology, which is genetically designed to "switch off" a plant's ability to germinate a second time, the biotech industry collectively owns at least three dozen patents that control either seed germination or essential plant germination processes. This privatization of a plant's genetic resources puts not only agricultural research in developing nations at a disadvantage, but might ultimately threaten the livelihoods of a majority of small farmers in Africa, Latin America, and Asia who largely depend on seed saved from one crop to sow in the next.

In developing countries, there may be a potential negative impact from Intellectual Property Rights (IPR) over biotechnological products or the processes used in producing them. IPRs have been held not only by private companies, but also by some public organizations making it impossible to use any aspect of biotechnology for improving major crop species without infringing a patent somewhere in the process. Because of IPRs, it has not always been possible to separate the biotechnology prospects from the business interests involved. A major consequence of IPR in agricultural biotechnology is that many developing countries which have not yet invested in biotechnology may never be able to catch up in the future.

Possibilities Sound decisions need to be based on diligent research. Biotechnology scientists are often highly specialized and technique-focused and may also need additional competency in handling the complicated issue of hunger and food security in developing countries.

Biotechnology holds tremendous possibilities for the developing world. The use of high-yielding, disease- and pest-resistant crops will have a direct bearing on improved food security, poverty alleviation and environmental conservation. GM crops will hopefully produce more yield on less land. This may increase the overall productivity and may offer developing countries a means to sustain themselves and reduce worldwide hunger. Ninety per cent of the world's 13.3 million "biotech crop farmers" are from developing countries. India, with 7.6 million hectares, is the fourth among the 14 "mega-biotech crop" countries. For instance, five million farmers in India are engaged in planting 7.6 million hectares of Bt or Bacillus thuringiensis, cotton, which protects itself from insects without requiring external pesticide. The shift to Bt cotton has been possible because of the 31 per cent increase in its yield, 39 per cent decrease in insecticide use, and higher profits equivalent to $250 per hectare.

It is now also possible using biotechnological approaches to increase the extraction of oil from a plant source up to 90 per cent. With the depletion of world hydrocarbon reserves, in the future it is probable that plant oils, such as biodiesel, may compete in terms of price and quality with oil, coal and gas. Final Thoughts The world's food supply is abundant, not scarce. The world's production of grain and other foods is sufficient to provide at least 4.3 pounds of food per person, per day. The real reason for hunger in the world is poverty, which often strikes women--the nutritional gatekeepers in many families--the hardest. Economists argue that resolving hunger requires political solutions and not just agro-technical solutions. According to them, instead of looking at biotechnology as a yet unproven and non-existent breakthrough, decision makers should look at the full body of research that shows that solutions to eliminate hunger are not technological in nature, but rooted in basic socio-economic realities. This is not to say that technology, including biotechnology, does not play a role in reducing, say, malnutrition, but there is no technology that can override the immediate political and social forces that keep people poor and hungry. The global biotechnology industry has funnelled a vast majority of its investment into a limited range of products that have large, secured markets in the First World -- products which are of little relevance to the needs of the world's hungry. Biotechnology has applications that can significantly solve the problem of world hunger. Green is the colour of agricultural biotechnology, of fertility, self-respect and well-being. In my opinion, policymakers should pragmatically consider modern biotech discoveries and assets as an important tool for solving the problem of global hunger.

Sora: OpenAI launches tool that instantly creates video from text

Model from ChatGPT maker ‘simulates physical world in motion’ up to a minute long based on users’ subject and style instructions

OpenAI revealed a tool on Thursday that can generate videos from text prompts.

The new model, nicknamed Sora after the Japanese word for “sky”, can produce realistic footage up to a minute long that adheres to a user’s instructions on both subject matter and style. According to a company blogpost, the model is also able to create a video based on a still image or extend existing footage with new material.

“We’re teaching AI to understand and simulate the physical world in motion, with the goal of training models that help people solve problems that require real-world interaction,” the blogpost reads.

One video included among several initial examples from the company was based on the prompt: “A movie trailer featuring the adventures of the 30-year-old space man wearing a red wool knitted motorcycle helmet, blue sky, salt desert, cinematic style, shot on 35mm film, vivid colors.”

The company announced it had opened access to Sora to a few researchers and video creators. The experts would “red team” the product – test it for susceptibility to skirt OpenAI’s terms of service, which prohibit “extreme violence, sexual content, hateful imagery, celebrity likeness, or the IP of others”, per the company’s blogpost. The company is only allowing limited access to researchers, visual artists and film-makers, though CEO Sam Altman responded to users’ prompts on Twitter after the announcement with video clips he said were made by Sora. The videos bear a watermark to show they were made by AI.

Sora can create videos of up to 60 seconds featuring highly detailed scenes, complex camera motion, and multiple characters with vibrant emotions. https://t.co/7j2JN27M3W Prompt: “Beautiful, snowy… pic.twitter.com/ruTEWn87vf — OpenAI (@OpenAI) February 15, 2024

The company debuted the still image generator Dall-E in 2021 and generative AI chatbot ChatGPT in November 2022, which quickly accrued 100 million users. Other AI companies have debuted video generation tools, though those models have only been able to produce a few seconds of footage that often bears little relation to their prompts. Google and Meta have said they are in the process of developing generative video tools, though they have not released them to the public. On Wednesday, it announced an experiment with adding deeper memory to ChatGPT so that it could remember more of its users’ chats.

https://t.co/uCuhUPv51N pic.twitter.com/nej4TIwgaP — Sam Altman (@sama) February 15, 2024

OpenAI did not disclose how much footage was used to train Sora or where the training videos may have originated, other than telling the New York Times that the corpus contained videos that were both publicly available and licensed from copyright owners. The company has been sued multiple times for alleged copyright infringement in the training of its generative AI tools, which digest gargantuan amounts of material scraped from the internet and imitate the images or text contained in those datasets.
