"Our planetary impacts have increased since our earliest ancestors stepped down from the trees, at first by hunting some animal species to extinction. Much later, following the development of farming and agricultural societies, we started to change the climate. Yet Earth only truly became a “human planet” with the emergence of something quite different. This was capitalism, which itself grew out of European expansion in the 15th and 16th century and the era of colonisation and subjugation of indigenous peoples all around the world."
