Plastic waste
उत्तर
Plastic is something which we use on a daily basis and has become an inseparable part of our lives. Despite its various uses, one of the major disadvantages of plastic is that it is an environmental pollutant. Plastic is considered non-biodegradable because it is made of very long polymer chains, which take quite a long time to degrade. Moreover, none of the saprophytes contain enzymes to digest plastic and obtain its nutrients. Since plastic is non-biodegradable, its proper disposal is also important or it may lead to problems like choking of sewage system, resulting in overflow of drains and death of animals by consuming plastic bags.
