The Ministry for the Future

by Kim Stanley Robinson

The current rate of extinctions compared to the geological norm is now several thousandfold faster, making this the sixth great mass extinction event in Earth’s history, and thus the start of the Anthropocene in its clearest demarcation, which is to say, we are in a biosphere catastrophe that will be obvious in the fossil record for as long as the Earth lasts. Also the mass extinction is one of the most obvious examples of things done by humans that cannot be undone, despite all the experimental de-extinction efforts, and the general robustness of life on Earth. Ocean acidification and deoxygenation are other examples of things done by humans that we can’t undo, and the relation between this ocean acidification/deoxygenation and the extinction event may soon become profound, in that the former may stupendously accelerate the latter.
