Answer:

  1. Garbage Disposal is the responsibility of every citizen. If we continue to generate so much garbage, the spreading diseases will increase at large scale. Non-biodegradable waste like plastic, polybags also adds harmful factors to environment. We must ensure ways to reduce generation of garbage. Wherever possible, we must use recyclable material in our daily use.

  2. Yes it is possible to reduce the problems relating to disposal of garbage to a large extent. We should use those materials which are recyclable and avoid or reduce the use of non-biodegradable materials. While throwing out garbage in trash can, we should separate biodegradable waste from non-biodegradable and throw them in separate bins.
