This assumes humans are responsible, which they are demonstrably not! But it raises another question:
Charles Darwin's evolutionary theory is basically "survival of the fittest." Have any of you ever met a Greenie hypocrite who was not a Darwinist? I'll bet money if you asked the authors of this "study" they'd proudly call themselves Darwinists. Doublethink.
Yeah, why is this “Darwin” so incompetent that he can’t crank out more new species as the old ones go?
