National Parks )) National parks are large areas of public land set aside for native plants, animals and the places in which they live. National parks protect places of natural beauty. They also protect places important to Aboriginal people, and places that show how people lived in the past. There are many good reasons for having national parks. They provide a safe home for native plants and animals. They help keep the air and water clean. They help us to learn about the environment. National parks give us places to enjoy.
