Question

Plastics are very useful materials. Why then is there concern today about their increasing use?

Answer 1

Plastics are useful but today they have become a serious global environment and health concern due to their excessive use. This is because plastics are non-biodegradable. They cannot be decomposed by the microorganisms in the soil. Inappropriate disposal of plastics is a serious problem. It chokes drains and blocks the pores of soil, which hinders the absorption of water by soil. Plastic bags contaminate food because of the poisonous dyes associated with them. Moreover, burning of plastics releases poisonous fumes, which causes air pollution. These fumes also cause cancer.
