Plastics
A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, but many are partially natural.[1] A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable.

Biodegradable plastics are plastics that are capable of being decomposed by bacteria or other living organisms.
Two basic classes of biodegradable plastics exist:[1] Bioplastics, whose components are derived from renewable raw materials and plastics made from petrochemicals with biodegradable additives which enhance biodegradation
There are concerns that "Oxo Biodegradable (OBD)" plastic bags may release metals, and may require a great deal of time to degrade in certain circumstances.[8] Furthermore, OBD plastics may produce tiny fragments of plastic that do not continue to degrade at any appreciable rate regardless of the environment
Although few peer-reviewed studies or government surveys have provided estimates for global plastic bag use, environmental activists estimate that between 500 billion and 1 trillion plastic bags are used each year worldwide.[8] In 2009, the United States International Trade Commission reported that 102 billion plastic bags are used annually in the United States alone
It is a compound that is indestructible, even when it is melted the compound gas that is gives off is very harmful to our heath and environment; it weakens the ozone layer. Most plastic is
