Sea urchins threaten kelp forests because they multiply quickly and eat the roots of the kelp. Kelp forests form a habitat for many species of marine animals as well as absorb carbon and help to reduce the effects of climate change. Sea otters help to control sea urchin populations minimizing their impacts on kelp forests.
