Ecological Importance
Kelp forests are one of the most important marine ecosystems. And along with this importance kelp forests are also an incredibly threatened ecosystem requiring an immense amount of conservation. The Monterey Bay Aquarium Research Institute (MBARI) personally does a lot to keep these ecosystems alive and healthy, constantly advocating to the public.
By far the most important thing that kelp forests do is produce oxygen. ~70% of the Earth’s oxygen comes from seaweed, which should indicate just how vital these ecosystems are. Another important job of kelp forests is preserving endangered species. Many of the fauna I have mentioned are endangered such as grey whales, sea otters, and sunflower stars. The kelp flora becomes a safe haven that protects these species.
The biggest issue that kelp forests face is from within. When sea otters are threatened and their population declines, the predation on sea urchins stagnates. The urchins then over-graze and can completely decimate a kelp forest. This is also tied into the larger issue of climate change, as increased climate change leads to more otter predation. Kelp forests also suffer immensely from human pollution and runoff. Overall we must protect these ecosystems as they are vital to our survival.
