Some of the world's biggest challenges, including climate change and political violence, extend far beyond any one nation's borders.
Global catastrophes can occur for a number of reasons, and the Global Challenges Foundation's 2018 report highlights some of the main risks to humanity today. The foundation, created in 2012, works with researchers to publish annual reports on threats that could devastate at least 10% of the world's population. This year's report contributors include astrophysicist Martin Rees and multiple experts focused on disarmament affairs at the United Nations.
According to the foundation, the next 50 years will set the pace for humanity's survival in the next 10,000 years.
"Why care now? Because so much is at stake, too little is done, and if we wait until later, caring may no longer matter," the report's authors said.
