Mr. Saran was the president of a housing colony that was constructed near a very busy main road. After getting several complaints from the residents Mr. Saran planted some trees along the perimeters of the courtyard. a) What was the residents' complain about? b) What role do the trees have in this situation?

The people probably complained about the excess pollution of the air around due to the heavy traffic of vehicles that emit toxic carbon based exhaust gases into the atmosphere around.

Explanation:

The planting of trees will sure provide a moderate solution to the problem. Trees are known to remove carbon from the atmosphere and add oxygen back into the atmosphere. Living around or near a heavy road will leave one prone to exposure to toxic exhaust gases from vehicles that use fossil fuels like diesel and gasoline. The numerous carbon by-products of the combustion of these fossil fuels can have a harmful effect on the people around the area. To curb this situation, trees can be planted to help clean the air of excess pollution from these waste gases.
