So you know what is really cool? Making dirt from old food. All food comes from the earth and most can go back into it. When food is put in a pile in a container with some dirt and leaves, it breaks down and after a while turns into really great dirt for your yard and garden.
Composting is one of my favorite activities to help the earth! I like to compost because it makes me have less garbage and I get play with dirt! Click here for instruction on how to start a compost pile. Of course ask your parents if you can first!
