The fact "One of the things you do when you build soil is put kitchen trimmings into the compost." is illustrated with the story:1. when you peel potatoes, carrots and other vegetables and fruits, you put the refuse in a bucket.2. every day you dump the contents of the bucket in your compost pile3. you mix hay or leaves in with your food waste4. after a while it rots and you put it in your garden to enrich your soil
