Question
What is the role of plants in controlling air pollution and flood?
Solution
The plants clean the air. They produce the most important gas oxygen. They maintain a balance between the CO2 and oxygen. The burning of fossil fuels has caused air pollution by increasing the amount of CO2 in the atmosphere. Photosynthesis of plants use the CO2 and thus control air pollution. Plants make the soil more compact as their roots hold together the soil particles and they lower the speed of the water and thus protection from floods.
