The earth without art is just "eh"

Worst case, I'd guess we could fix global warming by adding a very small dose of "nuclear winter"; just 2-3 nukes should do. We'd have to aim them somewhere that wouldn't retaliate and send nukes back... So I'd say that nuking Antarctica would be the best way to save the glaciers.

Politics isn't designed to choose a good leader, it's designed to choose the best leader from the given candidates, and usually none of them are good.

Cashier at the checkout: Did you find everything you were looking for?
Me: Of course. I'm buying stuff, aren't I?
If I came to the store to buy one thing specifically, strawberries for example, but didn't find it, then there are two ways that things could go:
I could continue shopping and buy other things, and then come back tomorrow to see if you have strawberries in stock. Then what if you still don't have strawberries? I'd have to check again the next day. If you never had strawberries in stock then I'd have to come back every day and buy some things every time. All of us poor strawberry-lickers would be shopping more than ever, but without the satisfaction of actually getting any strawberries. (1000 character limit)...

(continued)... Eventually Greedy McMoneybags, CEO of StoreCorp, would realize the potential profits and order every store to stop selling strawberries, but leave the signs up so that we still have hope that they will be in stock again soon. Farmers would be unable to sell their strawberries and would give up and grow different crops, counting strawberries as a worthless weed now. Strawberries would go nearly extinct before we realize how much of a jam we've gotten into. As the strawberry-less start to riot in the streets, world leaders would scramble to salvage the remaining strawberry crops around the world, eventually clashing and starting world war 3.
...or I could just walk out of the store, empty handed, and maybe shop at a competitor on the way home; finally breaking the perverse incentive for stores to intentionally be out of stock, and preventing nuclear war.
