End of the world

The Atlantic magazine, in its July/August issue, asked various people the following question:  “How and when will the world end?”

I thought environmentalist Bill McKibben gave the best answer.  Here it is:

In a sense, the world as we knew it is already over.  We have heated the Earth, melted the Arctic, and turned seawater 30 percent more acidic.  The only question left is how much more fossil fuel we’ll burn, and hence how unfamiliar and inhospitable we’ll make our home planet.

Birds, with their tiny brains, never crap in their own nests.  Humans never learned that basic lesson.
