Will humans cause their own extinction?

Scientists say there is relatively low risk of near term human extinction due to natural causes. The likelihood of human extinction through our own activities, however, is a current area of research and debate.

How are humans causing extinction?

The current extinction crisis is entirely of our own making. More than a century of habitat destruction, pollution, the spread of invasive species, overharvest from the wild, climate change, population growth and other human activities have pushed nature to the brink.

Imagine: food or water scarcity intensifying international tensions, and triggering nuclear wars with potentially enormous human fatalities. This way of thinking about extinction highlights the interconnectedness of existential risks.

Can humans really cause their own death?

Steve Luby, MD, an epidemiologist and the director of research for Stanford’s Center for Innovation in Global Health, sees hockey sticks on chart after chart of the various ways that humans can cause our own demise.
