Extinction is the process of particular animal or plant species die out. After the extinction there will be no more individuals of that species alive anywhere in the World. From early ages to this point in time over 99% of all the species have gone extinct. But sometimes extinctions happen at a much faster rate than usual. For example, at the end of the Cretaceous period 65 million years ago, 6 mass extinction caused the death of many different types of animals and plants, including the dinosaurs (National Geographic). In ancient times causes of extinction have generally been occurred by natural earth processes such as geological transformation of the Earth 's crust, species interactions and major climatic oscillations. On the other hand, since modern day the reasons of extinction have been dominated by the human activities with the onset of accelerated technologic developments and human population growth. Nowadays human intervention to the nature has major negative impacts on rapid extinction. Hunting, habitat destruction, disease and parasitism, introduction of alien species to an environment, pollution and over exploitation are the some of the main reasons of extinction of species (Hogan,2014). Habitat destruction elements include agricultural land conversion, deforestation, overgrazing and urbanization. These can also cause of major biodiversity loss. Overexploitation consists of intensive mineral and other geological resource extraction, fishing or hunting threatened
