List all the wastes that you generate, at home, school or during your trips to other places. Could you very easily reduce the generation of these wastes? Which would be difficult or rather impossible to reduce?

Solution

Wastes generated at home include waste paper, plastic bags, paper napkin, toiletries, kitchen wastes (such as peelings of vegetables and fruits, tea leaves), domestic sewage, glass, etc.
Wastes generated at schools include waste paper, plastics, vegetable and fruit peels, food wrappings, sewage etc.
Wastes generated at trips or picnics include plastic, paper, vegetable and fruit peels, disposable cups, plates, spoons etc.
Yes, these wastes can be easily reduced by the judicious use of the above materials. Wastage of paper can be minimized by writing on both sides of the paper and sending it for recycle. Plastic and glass waste can also be re-used. Substituting plastics bags with biodegradable jute bags can reduce wastes generated. Domestic sewage can be reduced by optimizing the use of water while bathing, cooking, and other household activities.
The reduction of non- biodegradable wastes such as plastic, metal, broken glass, etc, prove to be difficult as they are not decomposed by the micro-organisms in the soil. Thus, they persist in the environment for long and cause harm to it.
