Global problems

3. Climate Change


Climate change affects all of earth’s environments and is thus a global issue. A report from the Organization for Economic Cooperation and Development (OECD) found that droughts and extreme weather would intensify globally, leading to poor crop yield, water shortages and even desertification. The worst-affected areas, Sub-Saharan Africa and South Asia, will have trouble adapting because per capita GDP is low; millions will be unable to grow or afford food and will starve.
As entire regions face food crises, global economic production becomes much lower, and nations have to care for hungry refugees that flee inhospitable conditions. To prevent the situation from becoming worse, the world must adopt more sustainable energy policies and waste management practices.

4. Antibiotic Resistance


Antibiotic resistance is another global issue that threatens the health of millions and the progress of modern medicine. In 2014, the World Health Organization (WHO) announced the discovery of drug-resistant E. coli, staph and pneumonia-causing viruses all over the world; it also found that 20 percent of previously treated tuberculosis cases were drug-resistant.
The emergence of antibiotic-resistant disease is extremely dangerous. Antibiotics that people use to treat serious infections will stop working and disease fatalities will increase. The global community will need to implement stronger restrictions on antibiotic use to curb drug resistance in deadly diseases.

5. Poverty


While many of the above problems exacerbate poverty in many world regions, poverty itself is a global issue because it leads to social problems that affect even the richest people. According to the research site Poverties.org, poverty leads to higher crime rates, more instances of substance abuse and greater susceptibility to infectious disease. This hurts economic productivity and can lead to instability. Poverty also is linked to terrorism. Consequently, the world must fight poverty to address other global issues.
The world’s current global issues are complex, interconnected problems that require concentrated action for systemic change. Any single global issue could become a crisis with huge economic and human costs. Only with strong international cooperation can the world solve global issues.
