Pollution can be reduced by the implication of "reduce, reuse, and recycle" approach.
We should reduce the over-exploitation of resources such as fossil fuels. For example, we must use public transportation as much as we can, one should commute by walk or by bicycle whenever possible et cetera.
We should reduce the use of non-degradable substances such a plastic bags. Instead, we must switch to substances which can be used again and again. For example, jute bags, glass bottles et cetera.
Lastly, one must try to recycle materials.
