One of the sophisticated, yet simple sounding, lessons in ecology is that natural selection does not / cannot foresee a future selection pressure.

In the past, human cleverness modifying materials was among our more successful adaptations, right up there with long-distance running and social groups. 

Now we have reason to rue outcomes of our clever material modifications: toxic waste, scarcity of essential resources, and this dreadful thermal alteration of the planet.

As I posted over at Climate Progress, we could go the way of the cyanobacteria, once the prevalent form of life, which produced so much oxygen as a byproduct that the world’s atmosphere shifted in favor of other life forms.

Cyanobacteria are still around, but they don’t pretend to have authority over the earth.  Or they aren’t telling.
