Recycle: Items such as plastic, paper, glass, and metals that are removed from the garbage can be recycled to make new items rather than being discarded with other waste.

Reuse: This refers to the practice of repurposing items. Plastic jam or pickle bottles, for example, can be used to store items in the kitchen.

Ans: The leftovers can be carefully kept and used in subsequent meals.

(b) If you and your friends are given the choice of eating on a plastic plate or a banana leaf platter at a party, which one would you prefer and why?

Ans: Paper from newspapers, notebooks, magazines, and other sources can be recycled. Plastic-coated and gleaming sheets are difficult to recycle. Plastic sheets are the only ones that cannot be recycled among all the other sheets. The recyclable papers are slightly thicker than regular paper.


(a) Collect different kinds of packaging material. What was the purpose of which each one was used? Discuss in groups.

Ans: Food items in a paper packet.

Crockery made of cardboard

Clothes, dresses, in the plastic covers

Showpieces are the glass covers.

Delicate objects are kept in wooden crates.

Bubble wrap made of plastic — for shipping packages.

(b) Give an example in which packaging could have been reduced?

Ans: If consumers began carrying their carry bags when shopping for groceries, veggies, and fruits, there would be no need to package those items with plastics, reducing packaging.

(c) Write a story on how packaging increases the amount of garbage.

Ans: Packaging adds to the quantity of waste produced since we continue to discard packaging materials in inappropriate locations. Furthermore, the majority of packing materials are made of plastic, which is non-recyclable and cannot break down correctly. These pollutants accumulate in drains, clogging them and causing pollution.

6. Do you think it is better to use compost instead of chemical fertilizers? Why?

Ans: Yes, using compost instead of chemical fertilizers is always preferable because compost is natural and enhances soil fertility. Chemical fertilizers, on the other hand, deteriorate the soil and, in the long run, lead to sterility.
