Biodegradable substances are generally things that are organic in nature. This means they are substances that are made from things that were living at some point. Examples of biodegradable substances include paper which is made from trees, meat products which come from animals and leather products.
Nonbiodegradable substances are the opposite of biodegradable since they do not come from things that were once living. A good example of a nonbiodegradable is plastic which does not decompose no matter how long it remains on Earth.
In order to keep the environment safe, human beings are encouraged to use biodegradable products since they do not pose any threat to natural habitats or wildlife.
