Question

What are the 2 main sources of air pollution?

Answer 1

transportation...

Factories...

both lead to greenhouse gas emissions...

I don't know for sure, that was just a guess...

Answer 2

Air pollution can be classified into two major categories/sources:

The first one is "Anthropogenic sources" (human activity) mostly related to burning different kinds of fuel...

Under this are:

"Stationary Sources" as smoke stacks of power plants, manufacturing facilities, municipal waste incinerators.

"Mobile Sources" as motor vehicles, aircraft etc.

Marine vessels, such as container ships or cruise ships, and related port air pollution.

Burning wood, fireplaces, stoves, furnaces and incinerators .

Oil refining, and industrial activity in general.

Chemicals, dust and controlled burn practices in agriculture and forestry management, (see Dust Bowl).

Fumes from paint, hair spray, varnish, aerosol sprays and other solvents.

Waste deposition in landfills, which generate methane.

Military, such as nuclear weapons, toxic gases, germ warfare and rocketry.

The second is "Natural sources"

Under this are:

Dust from natural sources, usually large areas of land with little or no vegetation.

Methane, emitted by the digestion of food by animals, for example cattle.

Radon gas from radioactive decay within the Earth's crust.

Smoke and carbon monoxide from wildfires.

Volcanic activity, which produce sulfur, chlorine, and ash particulates.

Answer 15

Since you posted this in global warming, I'm assuming you mean greenhouse gases (GHG). CO2 is a fairly weak GHG compared to methane which is 21 times as potent a GHG. Three of the leading sources of methane are trees, rice paddies and cows, so I guess we'd have to blame them. Trees produce up to 30% of the world's methane every year, while cows and rice fields produce most of the balance. Overall, about half of GHG-caused warming is due to methane, not CO2.

CO2 isn't quite the threat that the media claims according to Earthsave.org : "...this overstates the effect of CO2, because the primary sources of these emissions—cars and power plants—also produce aerosols. Aerosols actually have a cooling effect on global temperatures, and the magnitude of this cooling approximately cancels out the warming effect of CO2. The surprising result is that sources of CO2 emissions are having roughly zero effect on global temperatures in the near-term!"

The remedy Earthsave.org offers is an immediate switch to vegetarianism and I assume a quick kill-off of all livestock to prevent them from emitting more methane. Just don't eat rice or you'll be adding to the problem again. It must be hard to be a good environmentalist nowadays.
