(a) Is garbage disposal the responsibility only of the government?
Ans:- It would not be fair to put the onus of removing the waste only on the government. If the people of the country are not aware of this issue, then the government alone cannot solve this problem. Therefore, the government as well as the people should extend full cooperation to solve this problem.
(b) Is it possible to reduce the problems relating to disposal of garbage?
Ans:- If the people of the country are fully aware then the waste disposal problems can be reduced. People should be made aware of the various types of smuses that can occur from waste and these will be resolved by the government to build public opinion about various ways to address them. So the only solution to the waste disposal problem is to create awareness among the public.

Ans:- I think it is better to use compost instead of chemical fertilisers. This is because chemical fertilizers are made in combination with different chemical fertilizers.
