Microbes May Have Fueled Permian Extinction, Earth’s Biggest

I’ve often wondered if some of the mass extinctions were caused by life itself.  Now, it sounds like that might have been true for the Permian Extinction.

If you think about it, the current Holocene Extinction, which we’re currently going through, is the same thing.  We’re life, and we’re causing extinctions all over the biosphere.   The question is whether we’ll eventually take it to the extent that we wreck our own food chain and go extinct ourselves.
