Can we farm the ocean without destroying it?

The oceans cover 70% of the world’s surface, but they only supply 2% of its food. Farming fish, the fastest growing food production activity in the world, could change that. But even though it’s been practiced for thousands of years, it still poses environmental challenges. Can we change that?

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.
