Mainly exhaust from cars.
There are a great number of things that could cause air pollution. These things include but are not limited to cars.
You're asking for a matter of opinion, and mine is no.
Electric cars must be manufactured, and that process causes pollution. Electric cars also require energy that must come from somewhere, and even solar cells must be manufactured, and therefore cause pollution in the manufacturing process. Humanity must learn to manufacture without causing pollution, or learn how ro deal with pollution.
In those areas where their is pollution the car will have bad impact on future generations as they have made horrible life of people due to which pollution is increasing day by day causing air pollution...
You can check out Craigslist for cheap cars in Denver. They list cars for sale by both dealer and owner.

Cargo ships generate more pollution than cars on a per-ship basis, but there are fewer cargo ships than cars, so overall cars contribute more to pollution.
Yes. All cars have begun to be built with air pollution control systems in them due to the increase in pollution in urban cities. Some cars have air pollution control systems and some don't.
Human beings themselves are the main reason for pollution. Pollution can be caused through electricity, fuels and transportation among many other factors.
