Some major problems facing society in the 21st century include: terrorism, overpopulation, global warming, the nuclear arms race and diseases. World superpowers have created numerous organizations and have spent billions of dollars to help address these problems.
The rise of Jihad terrorism spurred by the United States invasion of the Middle East is a major problem in the world today. Terrorist groups like ISIS, Al-Qaeda and Boko Haram have declared war on people and nations that they believe are a great evil. ISIS, a terrorist group, now occupies territory in Syria and Iraq that is almost the size of Indiana.
Overpopulation is a major problem in the 21st century and goes hand in hand with global warming. Global warming is characterized by heat waves, droughts, rising sea levels and species extinction. Overpopulation is a contributor to global warming because governments are constantly killing wildlife and trees in order to make room for more living spaces.
The nuclear arms race is a major problem in the 21st century because these weapons have the capability of wiping out millions at once. North Korea, Iran and Russia have spent billions of dollars amassing nuclear stock piles. Concerns about these deadly weapons getting into the wrong hands led to the passing of the Iran Nuclear deal in 2015, which was created to curb Iran's acquisition of nuclear weapons.
Diseases like AIDS, cancer and malaria kill millions of people in the world yearly.
