(b) If you and your friends are given the choice of eating in a plastic plate or a banana leaf platter at a party, which one would you prefer and why?
We will select banana leaf platter because it can be easily converted into manure by composting.
Plastic plates can be recycled but in this process it gives out harmful gases which pollute the environment. Plastic items cannot be converted into manure by composting.
4. (a) Collect pieces of different kinds of paper. Find out which of these can be recycled.

Packaging materials like thermocol, foam sheets, paper cuttings, cardboard, jute are used to protect the articles.Card boxes, plastic containers and tin containers are used to facilitate transportation of the packed materials.
(b) Give an example in which packaging could have been reduced?
Packaging of toys, clothes, shoes, chocolates can be reduced.
(c) Write a story on how packaging increases the amount of garbage.
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 of the places, the dustbins are full of chips and biscuit wrappers.
We should always avoid unnecessary packaging.

- Compost is eco-friendly and harmless.
- Compost maintains the texture and fertility of the soil.
- Chemical fertilisers destroy the natural composition of soil and have adverse effects on human health.
- Composting helps in recycling of matter and also in disposal of garbage.
- Leaching of chemical fertilisers causes water pollution and death of aquatic organisms.
