Sometimes the signs of things to come are right before our eyes, but the question is: do we notice them? And if so, how do we interpret them? During this episode, we'll take a closer look at some of those signs.

We'll explore an underwater ghost forest that holds important information for predicting the impact of climate change, we'll trek to weedy urban lots to examine what's happening with wild bee populations, and we'll find out why people who are paralyzed are finding hope in a new generation of prosthetic limbs.
