In Punjab, Its not only the Factories or Industries who have a major hand in air pollution, but agriculture is also in the line.

Firstly talking about the air pollution. Well we all have seen sights of agriculture fields set on fire after the harvest and the black ash layered soil left behind. But the huge amount of pollution caused and the harmful gases released into the air is not taken into account by the farmers.
According to the report generated by The Tribune (published in Dec 30, 2011 print), about 19 million tonnes of paddy residue is burnt every year in Punjab, which is indeed a big value.
Due to this, huge amount of lethal gases generated in air become the cause for respiratory problems. But till date, there is no such law or any ban on this activity.
But an alternate to burning paddy residue can be decomposing and later using it to enrich the soil. Or The Tribune report says that the left over can also be used to produce energy in co-generation plants to produce electricity.
But what we can do here is to educate our near and knowns who are agriculturist about this issue; Aware other people around us and head towards cleaner air to breathe in our city and state and then country!

Whether you’re considering switching your grocery bags, shopping bags, or trash bags, biodegradable plastic bags are a great alternative to regular plastic bags, in that they do not harm the environment during their whole life-cycle. As they are made from 100% natural materials, they leave no residue behind, and compost perfectly with organic trash, such as leaves, food, liquids, etc. Their main advantage – apart from not harming the Earth in their manufacturing, use, and disposal – is that they allow consumers to carry on with their regular shopping habits, or kitchen, yard, and compost disposal habits.
Biodegradable plastic bags do not harm wildlife nor marine-wildlife, since they biodegrade in water and if swallowed by animals, are digested quickly as they disintegrate. Since they are made from natural materials they go back to nature, just like any fruit or leaf would.
How To Make Sure Your Bags Are Biodegradable
1. Check the vendor’s claims about the biodegradable plastic bags. If the bags contain plastic (or technically called Polyethylene), these are not biodegradable bags
2. Check if the vendor has certification for the material. The only acceptable certification should be ASTM D6400 and/or DIN EN13432.
Biodegradable Plastic Bags vs. Paper Bags
Paper bags are environmentally problematic. They are heavier than plastic bags, and therefore require more trucks for transport, they need more energy to produce, and require a larger amount of energy to recycle. Also, paper manufacturers deplete significantly more CO2 than plastic manufacturers. The fact that they are made of trees is also an issue, but it is also what makes paper biodegradable.

On the other hand, biodegradable plastic bags require less energy to produce, are lighter and take less energy to transport. Also, they do not deplete CO2 into the environment during their manufacturing, and are made from all natural materials.
Biodegradable Plastic is still at nascent stage in India, but will surely come up as Environmental issues will rise.
