A landfill is a place where waste is held. Waste is usually buried in landfills. They have a bad smell and look bad, so they are usually made far from where people live. The garbage are usually there because it is the easiest way to deal with them. Although the poisonous chemicals in the garbage might leak out and it will be very damaging on the environment. Better ways to deal with waste are recycling and to just create less waste as much as possible. It will help the ecosystems greatly. Some largest landfills in US are Roosevelt Regional Landfill, Denver Arapahoe Disposal Site, Columbia Ridge Landfill, Pine Tree Acres, Atlantic Waste Disposal, El Sobrante Landfill and Recycling Center, McCarty Road Landfill, Sunshine Canyon Landfill, and Newton County Landfill & Apex Waste Center.
