Water crisis: Preserving fresh water sources is crucial to survival

Water crisis: Preserving fresh water sources is crucial to survival | Sustainability | GZERO Live

Over 70% of the Earth's surface is covered in water, but less than 0.02% is fresh water in lakes and rivers. An even smaller fraction of that fresh surface water is safe for humans to consume and farm. Still, according to Brian Richter, President of Sustainable Waters, humans are drawing too heavily on those resources without allowing replenishment.

What's worse, climate change is threatening to exacerbate the problem by drying out some already overstressed water sources, like the Colorado river.

"By the year 2050, we could have between 20 and 30% less water in that river system because of climate warming," he said during a GZERO Live event organized by the Sustainability Leaders Council, a partnership between Eurasia Group, GZERO Media, and Suntory. Watch what he says to find out why he's still hopeful humans will adapt.
