Objectives of• To eradicate the ill-effects of development and effecting our environment directly
or indirectly.
• To bring positive changes in the society by public awareness.
• To reduce the side effects of the rapid development and commercialization on agricultural sector through better use of technology.
• To curb the root cause for the growth of bacteria, viruses’ causing seasonal diseases is to be prevented.
• To provide technical monitoring of pollution.
• To reduce domestic pollution.
• To compensate pollution by increasing green area.

Plantation of trees
Trees:
• Help to settle out, trap and hold particle pollutants (dust, ash, pollen and smoke) that can damage human lungs.
• Absorb CO2 and other dangerous gasses and, in turn, replenish the atmosphere with oxygen.
• Produce enough oxygen on each acre for 18 people every day.
• Absorb enough CO2 on each acre, over a year's time, to equal the amount you produce when you drive your car 26,000 miles.

Collection and disposal of domestic waste
• Distribution of dustbins to each house.
• Collection and proper disposal of domestic waste with the help of Nagar Nigam.
• Recycling of the waste as much as possible.
![Page 35: think green](https://reader037.fdocuments.in/reader037/viewer/2022110306/554d7c21b4c905390c8b4d2d/html5/thumbnails/35.jpg)
• Every year, around 500 billion (500,000,000,000) plastic bags are used worldwide.
• India's plastics consumption is one of the highest in the world.

Has adverse effects on human health
• The daily used polybag contains lead and cadmium.
• lead and cadmium are toxic elements which can adversely effect human body.

• If burnt, releases Hydrogen Cyanide, a carcinogenic gas.
Contributes all types of pollution

Polythene Bag Substitute
JUTE BAGS PAPER BAGS
![Page 43: think green](https://reader037.fdocuments.in/reader037/viewer/2022110306/554d7c21b4c905390c8b4d2d/html5/thumbnails/43.jpg)
Why should we shift from Polythene Bags?
• Non biodegradable• If dumped in the soil
causes harm to the plant life
• Threatens the life in the water bodies
• Polythene is harmful for animals if swallowed
![Page 44: think green](https://reader037.fdocuments.in/reader037/viewer/2022110306/554d7c21b4c905390c8b4d2d/html5/thumbnails/44.jpg)
How are Jute Bags made?
• Jute bags are manufactured from natural jute and can be bought at a very cheap price starting from Rs.20
![Page 45: think green](https://reader037.fdocuments.in/reader037/viewer/2022110306/554d7c21b4c905390c8b4d2d/html5/thumbnails/45.jpg)
Advantages Of Jute bag
• Biodegradable• One of the strongest
natural fibers• Relatively cheap to buy• Durable• Jute crops require little
water• Jute has low pesticide
and fertilizer needs.

Advantages Of Paper Bags
• 100% reusable, recyclable and biodegradable.
• Can be made at home too.
• A renewable resource - comes from trees.
• Require less energy than plastic to be recycled
• Pose less of a threat to wildlife
