Humans v nature: our long and destructive journey to the age of extinction

Although the debate is far from settled, it appears ancient humans took thousands of years to wipe out species in a way modern humans would do in decades. Fast forward to today and we are not just killing megafauna but destroying whole landscapes, often in just a few years. Farming is the primary driver of destruction and, of all mammals on Earth, 96% are either livestock or humans. The UN estimates as many as one million plant and animal species are at risk of extinction.
