National Cleanup Day is a day dedicated to helping clean our environment, so it looks nicer for everyone. It's a time for people to come together to help get rid of trash or litter in parks, streets, and other outdoor areas. National Cleanup Day is usually held once a year, but you can help keep your neighborhood clean all the time. On National Cleanup Day, you can join a group of people and walk around the area picking up any trash you see, like empty cans, bottles, wrappers, and more. You can also help by doing things like planting trees, picking up roadside garbage, or even painting over graffiti. Working together to keep our neighborhoods clean is a great way to help the planet!
