There are only 2 big threats and they are polution and loss of foods. Te biggest one can be said is the loss of food.
Korean people do not hate and hunt whales. It is the japanese who kills whales for food. The chinese are reported to hunt whales on certain occasions.
Blue whales don't need to protect themselves because their so big. They don't have any natural predators but their calves are vulnerable to killer whales. The only threat to adults are humans.
Right whales are called "right" whales because thy were considered the "right whales to hunt" - they are slow moving and float once killed. This is one reason why they were nearly wiped out. Now days the biggest threat to Right Whales is large ships. Ships often hit the slow moving whales which causes massive internal injuries. Northern Right Whales are far more endangered than Southern Right Whales because there are more shipping lanes in the Northern Oceans.
