Landfill liner

A landfill liner is like a big piece of plastic that is put on the bottom and sides of a place where garbage goes. Just like we put a liner in a trash can to help keep the yucky stuff from touching the inside, the landfill liner helps to keep the garbage from leaking out and polluting the soil and water. This liner is very important because when we throw things away, they can break down and create chemicals that are bad for the environment. The liner helps to keep those chemicals from moving around and causing harm. Think of it like a big bed sheet that keeps the garbage from getting out and causing problems.
