David Grinspoon Quote
What was the question again? Is it when human activity first became detectable in the geological record? When humans first left a clear global marker, or golden spike? When human-induced change to the landscape became obvious? When we became an important agent of climate change? When we started to be the dominant geological force or pushed multiple environmental variables outside their normal ranges? Each of these would give us a different answer. When we look at it in this way, we see there is no one beginning. None of the proposals is wrong. Each marks a different stage in the hominization of the planet. So rather than insist on a choice, I like to view them as a set. Together they describe a series of interesting waypoints in the development of the changing and increasing human influence. Entering
