Why Do Animals Become Endangered?
We all know the animal facts that they are going to extict, so what are reason for this? Here is the answer:
In the distant past, several species of animals became extinct through natural causes. There might have been a change in the climate of a particular region, and the plants or animals on which the species lived could have died out because of the change in the weather. Or one animal might have been destroyed by another that was stronger or faster.
Today many conservationists are concerned with human interaction causing species to become extinct. This is because human interaction has increased the rate of extinctions beyond what normally should occur in nature. More extinctions reduces the planet’s biodiversity and can have adverse affects for all life on Earth.
Some animals, like rhinos, tigers and bears are hunted in the wild for their skins, tusks and other products. Many of these large animals take a long time to reproduce and so are very close to extinction. Sea animals like whales and seals are also hunted for their meat and skins, while overfishing has caused many of the world’s fish species to decline in large numbers.

Furs, Skins, Feathers, Horns
Besides food, animals are often hunted for specific body parts like their fur, feathers, or horns. Sometimes these animals are the top predators and, therefore, do not have a large population to begin with. These species can be quickly hunted to extinction. In Africa, the elephant was heavily hunted for its prized ivory horns. The population went from many millions to a few hundred thousand. Today the elephant is protected, but the population continues to drop in some areas due to poachers. Another example is the tiger in China. The tiger was nearly hunted to extinction for both its valuable fur as well as its bones, which were traditionally used for medicine. Today it remains classified as an endangered species.
Loss of Habitat
One of the main threats to animals today is loss of habitat. This comes from the expansion of humans, especially from agriculture. As vast areas of land are cultivated to grow food, natural habitats are destroyed. This can destroy many of the cycles of life necessary for organisms to survive and for biomes to thrive.
Pollution from humans can kill off a species as well. This is especially true in fresh water biomes such as rivers and lakes. Sewage and run-off from industrial plants can poison the water. When one species is affected, other species can die off as well causing a chain reaction as the balance of the ecosystem is destroyed. Introduced Species When a new species of plant or animal is brought into an ecosystem it can become invasive, quickly taking over and killing off other species. It may also destroy an important part of the food chain causing many other species to suffer.
