What should be done to avoid contaminating air, water and soil?

1) Do not use plastic bags, they can be replaced with canvas bags, string bags and fruit sprigs
2) Save energy and water
3) Walking more than driving. This will reduce the amount of exhaust gas
4) Do not litter on the street
5) Separate waste (paper, plastic, glass, food waste)
6) Do not throw away old things in good condition. They can be donated to a charity or second-hand
7) Use paper on 2 sides (using unnecessary sheets as drafts or printing documents on both sides)
