Sea otters, sea kelp, and sea urchins connect in some way. There is a vast of kelp forests
in the sea, which continues to support marine life. The forests are a great agent in the absorption
of carbon dioxide. The forest depends on the environment to control the amount of carbon
dioxide in the atmosphere. However, the kelp forests continue to face some risks related to the
growth of sea urchins, which tend to love more of kelp than anything else does on the sea. Such
creatures are small and spiky residing in the sea.
Sea urchins continue to cause more pressure on the forests given that they do not have
predators; thus, they keep on multiplying, thus creating more pressure on kelp forests. Despite
the stress caused in the forests by the urchins, the seas otters tend to target the u...
