Why national parks are important. Write 8-10 sentenses

I think that national parks are important. There are some reasons. National parks help to save plants and animals in their natural habitat. And to preserve them for future generations. Some national  parks are closed for visiting. Rare and predatory animals live there. And there also  some  kinds of  parks, where people can watch animals and even contact  with them. It is  interesting  to watch  wild animals in their natural habitat. National parks are  beautiful  places where  person can be closer to  nature.
