Read the paragraph and answer the question that follows: Incessant combustion of fossil fuels emits toxic gases, polluting the air; urbanization results in deforestation and hence poor air quality; littering of plastic waste damages the productivity of soil and pollutes water bodies. Environmental pollution results in more serious consequences like – global warming, unexpected climatic changes, depletion of natural resources, species depletion, and various other adverse effects leading to a lowered sustainability of life on earth. Another prime contributor to the pollution of the environment is plastic pollution. Plastic bags those are not disposed of properly, reach the soil and water bodies, polluting them and damaging dependent lives. Being non-bio degradable plastic lingers around for years, rendering them useless. What is the prime contributor to pollution?
