Causes+of+a+species+becoming+Endangered

Many people know about endangered species, but few know about the causes of endangered species. Keep reading and you will find out the 5 main causes of endangered species. 1) Habitat Destruction-   People are over achieving with architecture. Building roads and buildings not only add pollutents into the air, but builders are clearing down forests and the habitats of animals. This can cause the animals not only having to adapt, but possibly having to relocate into an area unsutible for the species. This is a major cause of endangered animals.   2) Introduction of foreign species- A foreign species being introduced into the wild is a major cause of endangered species. The species may be kept as pets then introduced into the wild because the owner didn't want it anymore. The species being introduced may find a native species as food and kill them. This can cause a native species to fall and become endangered. 3) Overexploitation- Overexploitation is when something is hunted or harvested so fast, that the species does not have time to recover. This is another major cause, and why the atlantic salmon is now on the endangered species list, along with many others.  4) Pollution- Pollution is in occurence because of humans. We pollute the air with our factory gases, we pollute the ground with litter, and we pollute the ocean with oil. Pollution needs to be stopped ASAP. If we continue polluting the world the way we are now, hundreds, maybe thousands of species will be put on the endangered species list.

** 5) Natural Selection- **
Natural Selection is when animals naturally become enda ngered because of their characteristics. This also helps animals evolve, but the animals who have better instincts, characteristics, and survival skills are the ones that survive. The weaker species die out or go extinct.
