The sea urchins then overexploited their main food source, kelp, creating urchin barrens, areas of seabed denuded of kelp, but carpeted with urchins. No longer having food to eat, the sea urchin became locally extinct as well. Also, since kelp forest ecosystems are homes to many other species, the loss of the kelp caused other cascade effects ...
The Earth’s trees absorb more than 7 billion metric tons of carbon dioxide — about a fifth of what the world lets out into its atmosphere — and release it back as oxygen or bind it into ...
English: It's prime time for kelp - January is when crops grow vigourously, resulting in leaves up to fifteen feet long! Even better, kelp can be grown in conjunction with other delicious seafood like oysters, mussels, scallops and clams.

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.
In these areas, the loss of grass due to the presence of trees and other shrubbery leads to more erosion than when trees are removed. [207] Soils are reinforced by the presence of trees, which secure the soil by binding their roots to soil bedrock. Due to deforestation, the removal of trees causes sloped lands to be more susceptible to landslides.
