On the basis of the issues raised in this chapter, what changes would you incorporate in your lifestyle in a move towards a sustainable use of our resources?
Everyone should incorporate the changes in our life- style moves towards the sustainable use of our resources:-
1. We should promote afforestation (planting the trees) programs instead of deforestation (cutting down the trees).
2. We should carry paper bags and jute bags while leaving the house for the shopping or for taking vegetables etc. instead of taking polythene from the shopkeeper.
3. We should prefer walking or bicycle to cover short distances instead of going on scooty or automobile appliances for controlling the air pollution and the noise pollution as well. And, to cover the long distances we should take buses and vans or we can say public transport instead of taking personal vehicles.
4. We should switch off lights, fans, television which was unnecessarily on to save electricity or energy.
5. We should use pencils for the rough work so that paper can be used again and again.
6. We should stop the tap while brushing the teeth or stop taking shower, use bucket to save water for bathing.
7. Use water harvesting techniques like rain water harvesting system which will be very helpful for surviving in the extreme condition.
8. Use solar panels, hydro- power to save electricity.
9. During winters, wear extra sweaters or clothes to avoid the use of heaters or we can also take hot bags.
10. We should use stairs instead of taking lifts for maintaining our health and for saving the electricity as well.
