I have second-order Facebook contacts who are overt environmentalists. Some of them are self-consistent enough to actually admit that they think human population level is the root of all these problems. That is in itself probably true, but I can't quite be hypocritical enough to attack a phenomenon that supports my very existence.

To that:

"There are too many people." "You first."

But they don't have good operating knowledge of population dynamics and current birth rates. It's rather that they bought prior exponential analyses of exponential human population growth and never fully discarded it. They also appear to know that fossil fuels are a part of this phenomenon.

So there are Druids who walk amongst us.
