Is plastic biodegradable?

Many plastics do not biodegrade to any significant degree, regardless of environmental conditions, although some people do so very slowly with exposure to air, water, and light — both types that are best recycled or used to store energy. The biodegradability of plastics depends to a large extent on the type of plastic and where it ends up.
