Synthetic polymers are finding applications in almost all spheres of life and are making our life comfortable. Their large scale use has been based on their relative inertness to environment Process giving them durability for long time. However, their long durability is not altogether an advantage. These solid wastes remain undegraded for quite a long time and their disposal has created a serious problem of waste management. If the overuse of plastics continues, it will pose a serious threat to all of us. After reading the above passage, answer the following question : Is it advisable to continue with overuse of plastics due to their immense use in our daily life?
