Restoring California's underwater forests
Often described as underwater rainforests and the \u201clungs of the ocean\u201d, kelp forests line as much as 25% of the world\u2019s coastlines. They provide important shelter and food for fish and other marine life, and are vital for our oceans\u2019 ecosystems. However kelp is under severe threat because of climate change, warming seas and overfishing. We look at projects in California aimed at stemming the decline of kelp including how scientists are growing it in a laboratory to be planted at sea as well as tackling a key cause of kelp degradation - sea urchins.
