Today the most well-known kinds of animals who are endangered are blue whale, arctic bear, giant panda, gorillas and a lot of others. Blue whales, for example, die out because of lack of food. Plankton is the main food for him and because of the ozone layer destruction plankton disappears. Mountain gorillas disappear because of logging. The number of Siberian tigers decreased in Russia because of hunters.

Fortunately there are various organizations that protect wild animals and organize different events to make people aware of these problems.
