As climate change threatens coastal communities, seaweed farms can provide a solution. Seaweed, which requires almost no land, water, or greenhouse gases to grow, can also pull carbon out of the atmosphere and act as a sustainable substitute for carbon-intensive products like plastic.

In this video, experts and farmers from New Zealand and Maine discuss the potential for seaweed aquaculture to mitigate climate change, as part of TNC's collaboration with the University of New England and the University of Auckland.
