2. Discuss:
(a) Is garbage disposal the responsibility only of the government?
(b) Is it possible to reduce the problems relating to the disposal of garbage?
Solution:
a)
No, not just the government, but everybody is responsible for garbage disposal. We should bifurcate wet and dry waste, recycle non-biodegradable substances, and we should also reduce the accumulation of garbage in our houses and streets.
b)
Yes, it is possible to reduce the problems of garbage by scientific disposal of garbage; we can do it by bifurcation of different waste and also by recycling the waste materials.
3. (a) What do you do with the leftover food at home?
(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?
Solution:
(a)
Leftover food can be collected and used to form compost. Compost produces nutrients necessary for the growth and development of plants.
(b)
We would prefer to eat food on a banana leaf plate because it acts as a harmless substance which helps to form manure by the process of composting, whereas plastic plates cannot be converted into harmless substances by composting. Plastic plates are not degradable, hence can persist in the environment and cause many problems.

5. (a) Collect different kinds of packaging material. What was the purpose for which each one was used? Discuss in groups.
(b) Give an example in which packaging could have been reduced?
(c) Write a story on how packaging increases the amount of garbage.
Solution:
(a)
Different kinds of packaging materials used commonly are given below:
-
Cardboard – Shoes, bulbs, soap, and other boxes.
-
Plastic Bags – Toys covers, shopping bags, sarees bags, etc.
-
Wooden Boxes – Fruit baskets and boxes for hardware.
-
Jute Bags – School bags, vegetable bags, shopping bags, etc.
(b)
By reusing the packaging material, we can reduce the accumulation of garbage.
(c)
The basic purpose of packaging is to protect the product from tampering and to maintain its freshness and purity. However, most of the packaging material is used to beautify the boxes and make them look attractive on the shelves. Unfortunately, a large volume of packaging material goes waste and is thrown into the dustbin.
For example, in most places, the dustbins are full of chips and biscuit wrappers.
It unnecessarily increases the amount of garbage. It also increases the cost of the product due to unnecessary packaging. We should seriously consider how to reduce unnecessary packaging.
