Answer 2

Answer:

Answer to (C)

Respected Principal, teachers and my dear fellow students. I wish you all a very good morning. I feel very honoured and privileged to stand here today, because our school is celebrating the World Environment Day with the rest of the world. Today I wish to speak a few words on the harmful effects of the use of plastic products.

Plastic products are not bio-degradable and can remain unchanged for many years. This adversely affects the fertility and the quality of the soil.

Plastics products including plastic bags are a health hazard. Exposure to toxic chemicals emitted by plastics causes cancer, decreases the effectiveness of the immune system, and are responsible for many other diseases.

Dumping of plastic bags, plastic bottles, etc. has created an unhygienic condition to our environment. Plastic litters has become a major pollution to our surrounding.

Our freshwater sources like rivers and lakes are becoming dumpsters for plastic bags.

Plastic products, especially plastic bags find their way into rivers and oceans. They are swallowed by fish, seabirds, and other marine creatures leading to death by suffocation.

Since plastic bags, plastic bottles and other discarded plastic products do not degrade, they accumulate in drainage and sewerage systems and block the flow causing waterlogging.

Plastic products including plastic bags are often disposed off by burning and this releases poisonous gases into the atmosphere. This pollutes the air we breathe and increases global warming.

Some of the ways to reduce the use of plastic products and thereby reduce harmful effects on our health and our environment:

1. Say "No" to plastic bags given by shopkeepers. Refuse any plastic bags from shop owners when you are shopping. It is best to carry your own shopping bag.
2. Carefully separate plastic products from other garbages for recycling.
3. Stop buying plastic products. When there is less demand, the manufacturing will decrease.
4. Replace plastic bags with bags made of biodegradable materials like cotton and jute.
5. Stop burning plastic as a means of waste disposal. The toxic gases released pollute the air we breathe. It increases global warming.
6. Don't buy bottled water. Carry your own nonplastic water bottle.
