Summary

The annihilation of biological diversity is one of the most severe human-induced global environmental problems. Species and populations are being driven to extinction every year at so high a rate, that Earth’s assemblage of plants and animals is now well into a sixth mass extinction episode. The most recent Living Planet Index has estimated that wildlife abundance on the planet dropped by some 60 per cent between 1970 and 2012 (WWF, 2016). The richest biota the world has ever seen is disappearing in the blink of an eye from the perspective of geological time. And humanity is busily making it worse.
