Agreed with Merrie and stopsweating.
We should do our minimum contribution just by disposing the waste properly in the bins and to recycle the recyclable items. Recycling would prevent the grow of unwanted bacteria, big piles of waste in your surrounding. I have seen solar chairs made of reusable materials, the idea is amazing, saves energy and provider you seat to sit.
Likewise, we can do some creative work with the reusable items to cut our bills and save the energy.
All creative ideas are welcome here.
