Earth-historical development of biodiversity:
It is not climate change but the anthropogenic biodiversity loss that is the greatest challenge to mankind. Thereby, climate change and biodiversity loss are two tightly coupled consequences of the fact that we humans exploit Nature, our vital resource, too intensively. A brief look at the history of biodiversity evolution illustrates how dramatic this man-made biodiversity loss actually is.
Over the last 500 million years biodiversity has increased, but this continuous increase was interrupted by five major mass extinctions, caused, for instance, by volcanism or by the impact of a major celestial body which initiated relatively rapid climate change leading to mass extinction.
It is obvious that we humans are heading towards a 6th mass extinction, which is caused by our growing destruction of natural ecosystems and by man-made climate change and which already now is impacting the next 33.000 human generations. The earth history can teach us important lessons concerning the future impact of this man-made mass extinction.
