California Academy of Sciences: Reducing San Francisco's Landfill Waste

A landfill is a big, deep hole. Items placed in a landfill sit there forever, producing methane gas, which contributes to global warming. 

To prevent this, San Francisco aims to divert as much waste as possible to recycling and composting facilities. In just 2-3 months, a banana peel in the compost facility can become compost, rich in nitrogen and other nutrients directly benefiting plants, making a rich soil for farmers. In this lesson, students learn about decomposition and landfills, and learn how to sort their trash into the appropriate bin.
