We're running out of water.

Possibly in the next few decades.

"Human beings will definitely have conflicts over this," says David Zhang.

How many years do we have until a civil or global war breaks out over this? How many legislators are trying to come up with policy about water rights? Access to the freshwater in the Great Lakes is already becoming an issue. I'm guessing the number of people in Congress who are worried about this can be counted on two hands.

Now, how many legislators are trying to battle about the contents of your uterus or what kind of people can get married?

I hope I've made my point. (We're all gonna die.)
