What does "Biodegradable" mean?

A biodegradable product can dissolve easily in the environment without destroying nature. It’s the opposite of plastic and Styrofoam, which harm the environment. If everything was biodegradable, our world would be extremely clean! Unfortunately, products that are biodegradable are not used worldwide yet.
