Landfills are overflowing then we have to find new places to throw trash
They take the garbage to landfills and bury it in the ground.
Americans threw away more than 251 million of garbage in 2006.
Sometimes chemicals from the trash can contaminate the soil and eventually the groundwater we need for drinking.
Scientists predict that it could take a glass bottle about 1 million years to biodegrade and that some materials like styrofoam will never biodegrade.
Many materials that end up as waste in landfills contain toxic substances.
Over time these toxins leach into our soil and groundwater and become environmental hazards for years.
Land pollution is anything that damages or contaminates the land.
