Where Does Your Garbage Go? Most of the trash that people throw away ends up in landfills or dumps. The process starts when we put our household trash by the curb to be picked up. Garbage trucks go into neighborhoods to pick up the trash. Then they bring it to the landfill where the trucks dump out all the trash. Next, machines push the trash into big piles. Finally, the piles are covered with dirt so more trash can go on the top. Landfills- areas where trash is taken

Trash decomposes at different rates. Some trash takes a long time to decompose, causing the piles to get too big. We are running out of room for new trash. Decompose- to rot or break down glass aluminum plastic paper food 500 yrs 400 yrs 300 yrs 200 yrs 100 yrs 50 yrs 25 yrs 0 yrs less than a year

Questions 1. What three things happen to trash as soon as it reaches the landfills? (Hint: Write your answer using commas in a series.) 2. Which would decompose faster, a paper bag or a plastic bag?

Answers 1. After trash reaches the landfill garbage trucks dump it, machines push it into piles, and soil is placed on top. 2. A paper bag would decompose quicker because it is made from trees. Trees are a natural resource which decompose faster. Plastics are man-made and decompose slowly.

4. If landfills become too full, we would lose land that could be used for places such as: homes, playgrounds, and schools. The Earth would become more polluted and eventually we would run out of space. What other ideas did you come up with? End of activity 3. Trash that would take years to decompose include: glass aluminum plastic
