Solution for Pollution issues in villages

I am born in Rajasthan’s small town. After living in multiple western countries in europe and Canada, i was back in 2022 to india.

I feel major problem to tackle for rajasthan is reducing pollution level in air and water at grass root level in villages. If it happens, it will give people source of revenue due to tourism, because we have no lack of natural beauty and hospitality.

I want to start something from my hometown itself. Please suggest how to start.
