Jeremy Paxman interviewed two biodiversity and climate change experts on BBC Newsnight tonight. Elizabeth Kolbert, author of Sixth Extinction and Emma Duncan, Deputy Editor of The Economist. Paxman asked if extinction was just a natural part of evoluction. Colbert said yes, but the rate of extinction was the problem. Climate change is the main driver of extinction. It is previously unknown for a mammal to become extinction over the period of our lives.
He then asked why should we be concerned about a spotted frog or wild cat going extinct. Duncan answered that humans need biodiversity for sourcing DNA to solve problems. She highlighted what happened when Mao ordered that China’s citizens kill all the birds, that this led to plagues. So the bottom line is that we need biodiversity to help us survive.
