Answer 2

Answer: The major food supply of the whales shows a large decrease.

The distribution of the whales in the world's oceans in a large way is effected by the availability of the food, finding mates and giving birth to offsprings. The baleen whales are feed mostly on the krill population which is a species of zooplankton, found abundantly in very cold waters. But these cold waters are not suitable for giving birth to the offsprings.

The non-availability of the food can decrease the numbers of the whales to a considerable levels.
