Whaling is the main reason. When it was first started, whale numbers were pretty high. Now however, whaling has gotten more serious, and whalers only use the meat off the whale. To add to this, whales have a low recovery rate, and so they reproduce very slowly. Within a century, whales will be extinct if whalers don't stop now. They are beautiful creatures and don't deserve the painful death they get.
There are now less whales in the food chain because of popular demand in countries such as Japan for whale meat. Also because as the ozone hole depletes more Ultra Violet rays come through and melt the ice in Antarctica which causes the phytoplankton which live in the ice to decrease as their habitat is destroyed, which means the krill have less to eat which means the whales have less to eat and so they are left without food.
for their blubber for lipstick and shoe polish! :(
Whales are made up of meat, fat and many other materials that are in demand on the market. Nothing goes to waste. Whales are harvested to make money.
Whaling. Research it.

The whale population has decreased dramatically from the time in which whaling was a popular industry to the present. Whale oil is not used often today because whales are being protected.
