Another Reason to Lay Awake at Night

It used to be the bomb. I had thought that climate change was the current nightmare. Now we hear that we may be causing mass extinction of species.

I guess that's not a complete surprise, really.

Researchers found that species are going extinct three to 12 times faster than would be expected if there were no crisis.

That gives Earth between three and 22 centuries to reach the point of mass extinction if nothing is done to stop the problem.

It would be the sixth time in Earth's history that this has happened--none of them recent.

We'll have to keep an eye on this one.
