South Korean seaweed farms seen from space

NASA’s Goddard Space Flight Center has photos from January 2014 of seaweed farms around Sisan Island, South Korea.

Since 1970, farmed seaweed production has increased by approximately 8 percent per year. Today, about 90 percent of all the seaweed that humans consume globally is farmed. That may be good for the environment. In comparison to other types of food production, seaweed farming has a light environmental footprint because it does not require fresh water or fertilizer.
