Promote ocean farming by integrating seaweed and bivalves to increase wild fish stocks, absorb the pollution that leads to the formation of marine dead zones, and even reduce local ocean acidification. Growing more seaweed, in particular, will supply us with sustainable food for ourselves and our livestock and replace plastics, and fuels.
Unlike agriculture on land, kelp and bivalve mariculture, sometimes called “marine permaculture,” does not require clearing land or using harmful inputs like pesticides and chemical fertilizers. Moreover, the benefits do not stop at having more highly nutritious sea vegetables and delicious protein. Farming the red algae Asparagopsis taxiformis can help us reduce methane emissions from cattle (see Asparagopsis Nexus). Kelp derivatives can help restore soil health and stimulate crop growth. Both seaweed and bivalves can help reduce runoff pollution that threatens coastal waterways, and even reduce the acidity of seawater to help nearby species suffering from ocean acidification. Growing kelps at a commercial scale is also an important stepping-stone for an even more ambitious kelp-based climate solution (see Seaforestation Nexus).
