On the other hand the professor casts doubt onto this claim by stating because of the human hunting sea whales become wipe out. That situation force to orca to change the diet. Now orca hunt other sea mammals instead of sea whales.
Third, the passage claims pollution theory also explain uneven pattern of other reduce of sea species in Alaska.
