Habitats, which ought to be the most fundamental element that provide animals food and safe shelter, has longly been damaging in various ways. Millions of species are added involuntarily into the list of the endangered merely because of the loss of habitats. For example, one kind of the circumstance can be a widespread wildfire, which is extremely dangerous and fatal. As any kinds of animals undergo such situation, they would suffer pain and even the corruption of the species. This, however, is a nature phenomenon which would has possibly out-broken at any time in the history. In contrast, human-beings actions may cause destruction to habitats to a greater extent, which can also be split into two parts. The first one is the urbanization, which has gradually been taking the space of animals away from their own. “For example, in Maryland, 10 years ago every new person added to the state accounted for the loss of 1/3 acre of land; now, every new person causes the loss of 2/3 acre.” People who pioneered and build houses and structures upon their habitats gradually robbed their land away. Secondly, another term called mass deforestation contribute significantly to the loss of habitat as well. As people’s endless desire to the wood of the forests, millions of hired workers cut down countless trees annually, which provides birds and other species shelters. “Eighty percent of Earth’s land animals and plants┬álive in forests, and many cannot survive the deforestation that destroys their homes.”
