1.	Most plastic is manufactured from petroleum products. Petrol is the end product of a few million years of natural decay of once-living organisms like plants and animals. Petroleum's main components come from lipids that were first assembled long ago in those organisms' cells. So the question is, if petroleum-derived plastic comes from biomaterial, why doesn't it biodegrade? 1.Decomposers don't have specific enzymes for plastic decomposition. 2.Because of high molecular weight of plastic, it will sediment too deep inside earth where bacteria is absent. 3.Because of colours in the polythene bags, decomposers are unable to decompose. 4. Bond energy in polymer is higher.
