Near Extinction Of Animals

Due to my knowledge, the animals in this world have face a big problem namely, the problem of extinction. Extinctionis an evolutive process that leads to the disappearance of a species or a population. Factor that cause this problem is habitat destruction (due to agricultural land conversion, deforestation or urbanisation), increased human population, pollution, global warming, overhunting/fishing, poaching or the introduction of alien species to an environment.

     Many animals that we haven't see it before just can find through Internet. Thus, we must protect all of the animals that near extinction. This will help to maintain the sustainability of environment and our generation have the chance to see all of this special animals. Through the research of Institute of Zoology, there also have some types of animals that in danger of extinction.
