Unless you’ve been living under a rock, you’ve probably heard about the controversy surrounding “fracking.” But unless you’re a petroleum engineer or an environmentalist, you’ve probably got no idea what fracking is. The good green, pro-nature person in you wants to think, “Pumping uh…water and stuff into the ground…or, I mean, oil holes…yeah, that sounds bad.”

But you actually have no idea why, or why it’s being done in the first place.

Fortunately, the excellent YouTube channel Kurzgesagt has put together a short animation explaining why energy companies are pushing fracking, how it technically works, and what some of the negative consequences may be. While Kurzgesagt is objective enough to leave it up to you to decide whether it’s a good idea or not, I think the answer is pretty clear: This is an incredibly destructive way of prolonging the time before we feel the crunch of a fossil-fuel shortage.
