Animals are endangered in natural ways. In what extent do you support this idea?
By Mehedi

Introduction: From the Darwinian theory of evolution we understand that there are always some animals, which are on the verge of extinction due to the natural reasons. Extinction of some animals helps to produce the growth of some animals that are the fittest for survival.

Problems: Animals are endangered due to natural and man-made activities. Natural selection is a process where certain types of animals die by naural activities to enhance the possibilities of certain types of animals to survive, and it is a slow process. However, forest area and lives of animals have been reduced substantially in the last five decades because of man-made activitise like urbanization, civilization, farming, poaching, chemical and fertilizers, industrialization, Even the animal of north and south poles are disappearing as the human civilization has developed and expanded tremendously in this century.

Solution: As per the mentioned theory, human has developed from their ancestors, ape or monkeys and this lead the extinction of some spices. Similar situation can be observed from the extinct dinoasours those used to eat top of tress and causes their food finished thereby. It is the death of these massive animals paved the evaluation of human race. In general, there are three basic types of animals: carnivores, herbivores and omnivores. Animals are depended on each other. When a species of certain herbivore disappears, then the dependent carnivore is also endangered. As for example, due to huge poaching of Royel Bengal tigers increases tne number of deer in the Sundarban, the largest mangrove forest in the world. There are some natural and man-made activitise which led the extinction of some animals constantly from environment. Certain eating behavior, extinction of dependent species, deforestation, natural clamity like volcano, earth quack are some natural causes that pose threat to some animals to be endangered. Man-made activitise like degradation of natural habitat of animals; poaching, killing animals for food, lack of farming of animals etc. are the main reasons behind animal extinction(main opinion). In addition, a study says that a large number of marsh water and salt water crocodiles was beaten to death as they are very aggressive to human. Conversely, an excessive growth of certain animals can lead the extinction of dependent species. Natural selection is such an idea that says that when a species is endangered, the other species is developed and nurtured by nature. It's a natural process to select certain animals for survival. In this way, nature balances its ecosystem.

Example: The reasons for the distinction of animals and their habitat are also important in these days while poachers are very active with the latest weapon to kill lion, tiger,elephant and rhino and so on. A study suggest that excessive poaching of deer in "the Sundarban" causes the number of tigers decreasing. Cutting down of trees (logging), killing birds and aquatic creatures etc. are also reasons causing dependent animals to be endangered.

In conclution, we can say that estinction of some animals provides the chances of survival of other animals with better quality. This type of extinction done by nature is happened to make an ecological balance for animals living together. But, we must conserve and save our animals and protect their natural habitats to optimize our chances for survival and limit our activities that cause animal extinction.
