The urchins in turn grazed the holdfasts of kelp so heavily that the kelp forests largely disappeared, along with all the species that depended on them. Reintroducing the sea otters has enabled the kelp ecosystem to be restored. [159] [160]
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]
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 ...

There are about 72 species of sea grass around the world, and while they cover about .1% of the seafloor, they play an important role in maintaining a healthy ocean.
Deforestation in British Columbia has resulted in a net loss of 1.06 million hectares (2.6 million acres) of tree cover between the years 2000 and 2020. [105] More traditional losses have been exacerbated by increased threats from climate change driven fires, increased human activity, and invasive species.
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.
