Answer: Plastic was thought to be a boon but it turned out to be a curse. Plastic can be very harmful as it produces harmful gases when it is burned. As it is non bio degradable‚ it is harmful to the soil and takes hundreds of years to degrade or decompose. Plastic is a boon for man but it is a curse for the master. It makes life comfortable for man but life tiring for the environment. Once animals have eaten it and due to choking they die Plastic is very harmful to living things. We
