Facts about Kelp
- 06
Sea urchins in kelp forests can consume up to 30 percent of their body weight daily in kelp blades, playing a critical role in controlling forest density and preventing overgrazing.
- 05
Iodine extracted from kelp biomass contains approximately 20,000 to 40,000 parts per million, making it a historically important source before synthetic iodine production began in the early 1900s.
- 04
Kelp forests absorb carbon dioxide at rates 5 times faster than terrestrial forests, sequestering approximately 200 million tons of carbon annually in ocean ecosystems.
- 03
Harvested kelp in Maine and New England regions produces sodium alginate, a thickening agent used in over 100 food and pharmaceutical products including ice cream and toothpaste.
- 02
Kelp forests along the coasts of California, Japan, and South Africa support over 400 species of fish and invertebrates that depend on the dense underwater ecosystem.
