Extinction is a normal part of evolution, but the speed at which the Earth is losing species is abnormal. Scientists estimate that today’s extinction rate is hundreds, or even thousands, of times higher than the natural progression. It’s hard to quantify the exact number of species affected, but experts say it’s at least 10,000 species per year that go extinct. What’s driving this sped up process and how can humans help more species survive?
