Question

What is the role of plants in controlling air pollution?

Answer 1

A balance between the CO2 which occurs at the earth’s surface, CO2 dissolved in oceans and that found in marine and terrestrial sediments exist. The burning of fossil fuels increases the amount of CO2 in the atmosphere causing air pollution. Plants control air pollution because during the process of photosynthesis they take in CO2 from the atmosphere and in turn release O2. Thus decreasing the level of CO2 in the atmosphere.
