The sea is full of free, nutritious food. And you don't have to go scuba diving to get it. I interview Tanya Stiller who leads foraging classes with forageSF based out of San Francisco. We learned about the types of seaweed, how to harvest it, local laws, and the health benefits. Be sure to visit the website to see photos of all the seaweed and demonstrations, plus pictures of books and links to buy them. www.ThisOutsideLife.com/seaweed.
