Question:

What factors contribute to past and present changes in California's sea otter population?

Answers

Human activities and water pollution.

Explanation:

The population of sea otter was 3000 in the past but by providing good environmental conditions, the population of sea otter increases up to 10000. There are some factors that contributed in the decrease in sea otter population in the past such as human interaction and pollution of water etc. Human activities and pollution also cause a bad affect on other organisms living in the marine ecosystem.

White shark bites, parasites, food availability, habitat degradation are among some of the contributing factors threatening the recovery of the species. The greatest threat to a sea otter is the oil spills.

Hope this helps!
