Over 500 species will go extinct in 20 years because of human beings, a process that would have normally taken 10,000 years
In 2016, journalist Elizabeth Kolbert’s Pulitzer Prize-winning book The Sixth Extinction: An Unnatural History (2014) was voted No.1 in The Guardian’s list of the 100 best non-fiction books of all time. Not without reason. Kolbert had shown lucidly, with clear examples, how human beings are causing the sixth great extinction event on the planet. The previous five, over the past 450 million years, including the one that wiped out the dinosaurs, were all due to natural events.
