How do sea lions help the environment?
The proximate role played by seals and sea lions is obvious: they are predators and consumers of fish and invertebrates. Others may play a structural role by influencing the physical complexity of their environment; or they may synthesize the marine environment and serve as indicators of ecosystem change.
What is the biggest threat to sea lion?
Sea lion populations are plummeting for a number of factors – the biggest threats being commercial fishing and the disease Klebsiella.

Natives will start to lose a lot of their culture, if the Steller sea lion goes extinct. They will lose some of their food supply, and have to use their own money to buy store bought foods. Many will also feel that their nutrition will decrease.
