Solution for environmental degradation:
(i) we should use CNG instead of petrol and deisel.
(ii) for example 2 pesons working in same office and live in same colony then they should go in 1 car instead of the both go in different cars
(iii) we should use public transport
(iv) try to avoid vehicles like you are going to marcket which is near to your home then don't go in bike or other vehicle
