A hopeful book about climate change: Bren Smith is a former fisherman and a failed (because of Hurricane Sandy) oysterman who invented a new kind of living from the sea, restorative ocean farmer. His crop of kelp and bivalves growing on ropes suspended in the water requires no inputs; it simultaneously draws down carbon, filters nitrogen and replenishes the oceans. Beyond sustainable- it is regenerative! Also, the price of entry to this job is low and could put ocean communities back to work, creating new jobs both farming and processing the resultant seaweed and mussels, oysters, and other bivalves. Be prepared to order some seaweed once you are done reading: www.blueevolution.com. And you may want to lend money to Greenwave, Bren Smith’s nonprofit that trains ocean farmers:www.greenwave.org.
