As asserted rightly in the context, there are concerns for decline in sea otter poppulation in western coast of North America. There were some of the possible reasons listed in the paragraph, like it can be due to rapidly increasing polution in near by areas or increase in number of abnoxious predators. Detailed anaysis is cogently made in context abvocating that rapidly increasing pollution would rather be possible reason for deplete in popullation. Apart from the context, Speaker has made some cogent remarks on facts which gives convinving reason to get concreate conclusion.
Firslty, it is stated in paragraph that pollution would be one of the lethal reason for deplete in otter poppulation, as there are number of oil rigs and chemical industries near to affected coast. The water sample was duly analyzed and it was enough deadly to break the resistance of otters and thus would lead to lifethreatening infections and kill them. But, speaker has contradicted this statement stating that there were not otter corpse washed away on sea shore in any time during that regime. Thus it leads, that predator would had been possible options for the deplete.
Secondly, apart from the rate of decline of otter poppulation, there were parallely decline in number of other water species as sea lions and seals. so context is backing the surmise that water pollution has not limited the infecton to otter speacies but had also has affected other species. But speaker makes cogent contradiction that Orca whale which feeds on smaller whale, is possibly starving as whale on which they feed are being vanished from the areas nearby as due to human presence. So possibly orca have change the food chain and now feed on smaller mammals like sea lion and otters.
Lastly, asserted in context that above mentioned hyposthesis would explain the possible reason for deplete in other areas too, where we have uneven decline in otter population. But speaker has very kind remark to it stating that decline would rather not depend to things stated in context and as otter usually leave on shallow water in alakan areas where orca which is giant mammal would not able to easily come for hunting.
