Maybe Mother Nature has the right idea.

Rid the planet of these hideous human creatures. They don't care about their own environment and they don't care about each other.

To borrow a phrase from a very smart Astrophysicist:

"Nature is the ultimate judge, jury, and executioner. You can argue all you want, but if nature doesn't agree with you, you're wrong. Whatever bias you're bringing to the table, nature will decide."

Damn ... it's just taking so long.
