The fact that I can get well sourced, accessible and entertaining primers on a whole range of interesting science makes Potholer54 one of the best things on the internet. Ever.
I have no doubt that his series on the origin of life bumped up some of my 1st year science grades.
Probably the worst thing about it is that it's gradual. The apocalypse fetishists who hoard food and bullets seem to be ready for a sudden, population-dropping catastrophe. A slow, grinding one will starve out people far slower than even a Costco's worth of dehydrated food can outlast.
I'm saving a link to this video for the next time my denialist buddies start linking to blogs as to why you don't use bloggershit in place of scientific facts.
