First of all, before this question can be answered, the meaning of biodegradable first has to be established...
What does biodegradable mean?
Biodegradable is the term used for anything that can be broken down or decomposed when exposed to the environment eg wind, rain, bacteria in soil, when exposed for lengthy periods of time.
You have probably seen some plastic bags in recent years, which say that they are biodegradable. Well, this simply means that they can be broken down or will disintegrate naturally when exposed to the environment.
So, why are biodegradable materials useful for the environment?
Simply put, they do not clutter landfills and cause a build-up of harmful toxic materials. They can be broken down as if they were not there in the first place.
I found the following YouTube videos on some available biodegradable materials quite interesting...
