They’re going to kill everybody. They’re not as smart as they think they are. Idiots.
They will if they are allowed to do whatever they want. They should watch that movie ‘The Road’ or better yet read the book by Cormac McCarthy. It’s a book about a father and son trying to survive in a world where all the plants have died off. The book doesn’t say why, but the description of the weather makes it clear it’s either or both because of the sun being blotted out or the CO2 level on earth has gone too low. So what happens? The plants die out and then animals, and then there’s no more food and the people resort to cannibalism. Anyone trying to “dim the sun” should be shot.
