Instead of using synthetic sponges for your shower and dishes use a luffa! Sponges tend to collect bacteria and for heath reasons should be thrown out 1-2 times a week. But if they are not biodegradable, that is a LOT of waste filling up landfills. Additionally, the “antibactirial” sponges have a chemical called Triclosan which is officially a pesticide. Do you really want to be using that on your dishes? The best part about Luffas, are that they can be grown in your own backyard!
