The number of endangered animals has increased in our days. This is mainly caused by the man who selfishly destroys the habitats where many animals live to satisfy his interests. Another reason is the rapid growth of the population. This has created a greater need for more housing resulting in the destruction of the areas where the animals live. Also hunting is an equally important factor in reducing the population of some animals. But a contemporary cause is the phenomenon of climate change which has disturbed the climate and in general the natural balance of the earth. This change has brought many animals close to extinction such as the polar bear whose habitat is being destroyed every day. We can contribute to the protection of these animals by simply recycling. By recycling we will consume less energy which will slow down the climate change.
