National parks have a rich history in most modernized countries, specifically in the USA. They were first envisioned by Theodore Roosevelt with the hopes of protecting and preserving nature for future generations. In national parks, the natural ecosystem and environment is allowed to flourish the way nature intended it to.

This is important at preserving biodiversity because it protects the natural checks and balances found in the area. They also work to help prevent the natural animals found there from going extinct by habitat loss. National parks are also a key tool in educating the public.

People are allowed to go and observe nature, meaning they will want to preserve and understand it more. One national park not only protects the animals and environment found in its borders, it also works to help maintain the surrounding natural environment via pollen from natural trees and the purification element that nature has on the surrounding area.

When a developed or industrialized area is adjacent to the national park, the natural cleaning processes of producers often improves the air and water quality of the area. Yet many national parks are relatively far from any highly populated areas due to both the cost of land and the risk of contamination.

Another preserver of biodiversity linked to natural parks is the ability to release animals there. If an animal needed medical care, it would be easier for scientists to release it in a slightly more controlled environment that it is adapted for rather than into the human-tainted wild. Because of this, many national parks are near animal rehabilitation centers and scientific research facilities.

National parks are also an important tool scientists and wildlife conservationists use to help increase population numbers of an endangered species. They help these experts collect data on the wildlife in the area in order to better protect the ones whose populations are suffering, which helps improve biodiversity.

Another benefit to biodiversity found in national parks is the allowance of natural spread. This way competition doesn’t run too high and the natural cycles are allowed to continue. The water cycle is too often changed by human involvement, so if it is allowed to flow naturally, the organisms will be able to utilize it to its full extent.
