[Of course, humans have been intervening in natural systems and driving them out of whack since the start of civilization, even before.  However, unlike today, there was no pretense of scientific knowledge.

Oh, I have a good idea for restoring all the Earth’s ecologies to their former beauty.  Eradicate humanity.  OK, I am not the first to think of it.  Also, I do not hold the Sovereign Power to accomplish the task.

However, I want to point out one possible weakness of this organizational mandate.

Civilized humanity may be that the reason that the Earth is not a giant snowball at this very moment.  Why has the planet not returned to the Ice Age as one would expect from the geological data?  According to the cycles of the past 2 million years, glaciation should be going full tilt.

The answer is simple.  Heat is retained through the absorption of outward bound infrared radiation by an atmosphere enriched in biomolecules from anthropogenic sources.

Gaia may prefer our interference.]
