Coral reefs are magic underwater worlds that support 25 percent of all marine life. But climate change is threatening to wipe them out. Now scientists and conservationists around the world are racing to toughen coral reefs up. Is that enough to save these vital ecosystems?

We're destroying our environment at an alarming rate. But it doesn't need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we'll take a truly global look at how to get us out of this mess.
