Human Uses<\/h3>\n\n\n\n

Kelp is eaten directly as both human animal food. “Kelp ash” is used in glass, soap, pottery glaze, and fertilizer. Alginate from kelp is used in food, fabric, and medications. There is interest in using kelp to create biofuels (Smale et al. 2013).<\/p>\n\n\n\n

Fun Fact<\/h3>\n\n\n\n

Laminaria saccharina’s<\/em> southern limit is off the coast of Rhode Island (Smale et al. 2013).
Kelp forests can help lessen storm damage (Egen et al. 1990).<\/p>\n\n\n\n
