Look carefully to learn if, example, plastic bottles, plastic containers, cling wrap foil can be put the category of "garbage that can turn dirt." What do you think?
If you said "No," then you are correct. Old sandals, broken computers and erasers are in fact originally made petroleum, a resource found deep the earth drilling what are called "oil wells." These garbage items made petroleum won't turn dirt even after thousands years. This is because they are made resources that weren't originally found the earth and so they aren't part the cycle of living things the earth's natural recycling system.
