How animals effect their enviorment

[Viridis]

Sea lions eat urchins, without sea lions nothing controls the urchin populations, and the entire kelp forest in those areas can be lost to urchins munching, without these kelp forest abalones don't survive,greenlings can't eat, and many creatures cannot take necessary refuge.

Numerous things control the urchin population... Disease, Crustaceans, Sea Otters, Anarhichadidae, Semicossyphus pulcher, Balistidae, &c. all eat/help control echinoid populations. Maybe not to the same levels as sea lions (especially on the west coast of North America and the Galapagos), but they still contribute.

Imagine all the dog poop that would be all over the place if there were no flys and maggots to eat it all.
Some people can't clean up after themselves in their homes so the roaches and the mice do it for them.

Meant to say sea otters, not sea lions
