Nature's going to be doing a little thinning out in the coming centuries.
Under climate change nature has already become meaner and tougher, more like the "dog eat dog" parodies of social darwinist propaganda.
Climate change is tipping the Ark and some species are falling out. Other species dependent on those species are preparing to starve.
Scientists have observed this going on for some time now. Here's a current story in the news. (Strong salmon hearts may hedge against climate change-CBC.)
Yep, the story says, some species of salmon with special characteristics allowing them to survive climate change will survive. Others won't. In the end there will be fewer species of salmon. That's not really a victory.
