the vehicles are taking the air pollution
The gas that causes the biggest amount of air pollution has to be carbon dioxide. Due mainly to emissions from vehicles.
Vehicles release carbon monoxide into the air from the combustion of fuel in their engines. And the amount of such kind of pollution is very great, mainly in big cities.
52% of Mumbai's air pollution comes from the exhausts of vehicles
Most car salesman get commission. So few make a decent amount of money unless they are selling vehicles regularly.
obviously because to check the amount of emissions from our vehicles . no check eventually leads to more air pollution.
The only way to preserve clean air is to reduce the amount of air pollution. This is done by reducing emissions from human sources like vehicles, power plants, farms, and factories.
nowadays people use a lot of vehicles and even don't use the pollution check machine. The smoke coming out of the vehicles go up in the air and the carbon-dioxide present in it mixes with the air and the amount of carbon-dioxide rises . So, this causes air pollution and this air mixes with the wind carrying moisture and fall on earth as acid rain...
Overall they have the potential to reduce pollution slightly. There is a definite increase in the pollution during manufacturing. The pollution made while the car is moving is reduced by the amount of fuel saved. During the end of life cycle, the mount of pollution will be determined by how much of the cars end up being recycled.
Pollution abatement is reduction of the amount of pollution being created or existing in an area.
very
A new car produces far less *pollution because laws have changed over the years requiring car manufacturers to cut down on the amount of pollution that the vehicles put out. Also there is spell check for a reason.
