Between 98 and 99.9% of all species that ever walked, crawled, swam, flew, or ran for office anywhere on Earth are now extinct. As some species become extinct, others manage to adapt to a changing environment and thrive. It's called 'evolution'.

In other words, maybe it's time to take a deep breath and calm down a little. There's a lot we don't know and, despite the assertions of some people who should know better, and probably do, this whole subject is far from 'settled science.'
Maybe even time to give up the politically correct greeting, "Hi. The Koch brothers are eating your children" and go back to the old fashioned, "Hello," which is rumored to still be popular in some remote parts of the country and can be very soothing.
