She comes ashore in Crazy Town to discuss some of her experiences in the depths, the state of the world's oceans and marine biodiversity, the limits to growth, the wonders and disappointments of technology, and her belief in the accumulation of knowledge as a pathway for change. Sylvia's new book is called Ocean: A Global Odyssey. Support the show (https://www.postcarbon.org/supportcrazytown/)
