Sometimes you're faced with a decision in which both of your options have drawbacks. You're stuck between a rock and a hard place. We look at these moments of decision, and what is at stake. Should pregnant mothers stop taking their anti-depressants, risking their own mental health, in favor of the health of their baby? Should scientists try and capture a species of tiny porpoises to save them from extinction, even if the attempt to save them could potentially kill them? Plus, should we get rid of old industrial dams in hopes of restoring natural waterways, even though it could damage the existing ecosystem? On this episode, you're dam-ed if you do, and dam-ed if you don't.
