Littering is the act of throwing or leaving trash in places where it doesn't belong, like parks, streets, or beaches. This careless behavior can harm the environment, as plastic bags, cans, and bottles can take years to decompose. When litter is left behind, it can also hurt wildlife, as animals may mistake it for food or get trapped in it. Not only does littering create an unsightly mess, but it can also lead to fines and penalties in many areas. Communities often organize clean-up events to encourage people to take responsibility for their surroundings and keep public spaces clean and enjoyable for everyone.
