Smaller areas of anchored kelp are called kelp beds. They are recognized as one of the most productive and dynamic ecosystems on Earth. [ 1 ] [ 2 ] Although algal kelp forest combined with coral reefs only cover 0.1% of Earth's total surface, they account for 0.9% of global primary productivity . [ 3 ]
An American kelp farmer, Bren Smith of GreenWave explains his farming methods, including the symbiotic relationship kelp has with other seafood he grows. The earliest seaweed farming guides in the Philippines recommended the cultivation of Laminaria seaweed and reef flats at approximately one meter's depth at low tide. They also recommended ...
An alternative offset would be to cultivate kelp forests. Kelp can grow at 2 feet per day, 30 times faster than terrestrial plants. Planting kelp across 10% of the oceans (4.5 x the area of Australia) could provide the same offset. Additionally, the kelp would support a fish harvest of 2 megatons per year and reduce ocean acidification. Large ...
Kelp forests play an integral role in the health of the world’s oceans, one of the issues being discussed at the United Nations climate summit in Dubai. Based on early observations, efforts like ...
Kelp forests are some of the most productive ecosystems in the world - they are home to a great diversity of species. Many groups, like those at the Seattle Aquarium , are studying the health, habitat, and population trends in order to understand why certain kelp (like bull kelp ) thrives in some areas and not others.
Kelp forests are also some of the world's largest carbon sinks, and the Great Southern Reef therefore acts as a buffer against climate change. [7] Unfortunately, an estimated 95% of the giant kelp forests off the coast of Tasmania have died off over the past few decades due higher water temperatures and the long-spined sea urchin. [6] [8]
Kelp forests are some of the most diverse and productive ecosystems and in the UK cover an area similar in size to the country’s woodlands.
The largest seed in the world is the coco de mer, [1] [2] the seed of a palm tree. [3] It can reach about 30 centimetres (12 inches) long, and weigh up to 18 kilograms (40 pounds).
