Quotes from the news wire:
Thankfully, this is now a scenario that is science fiction. But as you can imagine, the consequences would have been absolutely dire, it's kind of hard to imagine, but you could think of us as humans all in wide-brimmed hats, sunglasses, caked in sunscreen, only going outside for five to 10 minutes a day when the sun was out.
