These succinct words capture the magnitude of our problem extraordinarily well. We need to heed reality and work towards a world that will not collapse: For 200 million years, the biomass of megafauna on the planets land surface remained at around 200 million tonnes, which he considers to be the planets natural carrying capacity. As recently as 300 years ago, that figure held, although humans and their livestock had become the dominant megafauna. Since then, however, this biomass has rocketed to 1.5 billion tonnes. We achieved that by tapping the energy in fossil fuels, in the process turning a carrying capacity problem into a climate change problem. Meanwhile, our efforts to grow ever more food and turn nature into money have obliterated ever more species. It means we now stand on the verge of Earths sixth mass extinction.
