Why Some Animals Become Endangered Species

It is worldwide knowkn that no creature exists in isolation, ecosystems are dilicate arrangements where plants and animals all depends each other for survival. The removal of a single species can disrupt the balance, conceivably set off chain reaction affecting others by breaking the food chain and altering the habitat where they live. Many animals and plants become endangered or extinct each year. Recently, however, the rate of them dying out increased dramatically. It is estimated that 27,000 species become extinct each year, about 3 an hour. Since 1996, scientists calculated that 124 types of amphibians, 1,108 types of birds, 734 types of fish, 1,096 types of mammals, and 253 types of reptiles became endangered. In Georgia, from total of about 650 species 141 are indengered and listed in Red Book, some of them, like Gazella subgutturosa, already become extinct. Why it happens and what can be done to save them? Animals can become endangered and even extinct for a number of different reasons. Some of them can be named as main, but there is one fundamental reason causing all others, Human.

There are listed many different reasons why particular species become endangered. Although there factors can be analyzed and grouped, there are many causes that appear repeatedly, like habitat loss, pollution, illegal hunting and global warming. An enormous parf of mass extinction is the loss of the animals` natural habitat. The highest rates of deforestation began on the 1990`s at a striking 16 million hectares a year. Commercial deforestation in the amazon rainforest seriosly reduced the population of many species and led to extinction of others.

To sum up the foregoing, there is big list of animals which are already extinct, and mayabe more which are endangered. Some say that it is cause of human activity, some say that it is natural selection. The fact is that extinction is a natural process, because humans have not been around forever to cause extinction. Nowadays People are dominating on earth and setting up living rules for others, like other dominating animals years ago, and it is not excluded that there will be time when Human will become extintc, by natural selection, by nature will.
