Well, mariculture provides a different way,” muses Evie Witten of Ebb Tide Ocean Farm and the Kachemak Kelp Hub in Homer, Alaska. “I'm an ecologist and I'm interested in addressing climate change conundrum in regenerative ways. Kelp is good because it provides both a source of food and biomass and can be grown in ways that are beneficial for coastal ecosystems and communities,” she adds.
