Land pollution is when humans spill or throw things that are not natural on the land. This can cause harm. Many people litter on land which can be toxic to plants and animals. Humans also dump toxic chemicals onto land. That means that other animals, plants, and even humans can get affected by it. Land pollution is a very big problem. Land pollution actually feeds into water and air pollution. When land pollution decomposes or decays, it turns into a gas that can pollute the air! Sometimes, land pollution can be swept into waterways and pollute the water. That is why we need to reduce and eventually stop water pollution.
