Permaculture showed us how to farm the land more gently. Can we do the same as we farm the sea?

As wild fish and other marine species get scarcer from overfishing and demand for 'blue foods' grows around the world, farming of the ocean is growing rapidly. Fish, kelp, prawns, oysters and more are now widely farmed. The ...
