Cow manure is a major problem for factory farms and anyone living near by. The primary impact is on ground water and surface water contaminated by the runoff. They are a leading cause of pollution only in areas local to factory farms.
Methane is a significant cause of global warming and cows do contribute minor amounts of methane, but the majority of methane is released by leaks from natural gas production and use.
Cows consume a great deal of feed. Most corn production is fed to cows in the United States. Farming is a major source of pollution primarily in the forms of pesticides, fertilizers, and soil runoff into surface waters, rivers and oceans. There is a large dead zone in the Gulf of Mexico around the mouth of the Mississippi River that is caused primarily by Midwestern farm runoff. The nutrients in the run off cause bacteria to grow, which consumes all the oxygen in the water and then fish cannot survive causing a "dead zone". To the extent that farming is done to raise cattle feed cows are responsible for that pollution too.
Farm equipment has very little air pollution controls and so there is a lot of pollution from tractors, and other farm vehicles. Even though there are not a lot of farm vehicles they pollute at rates that may be several thousand times higher than passenger cars and so in farming areas can cause much of the local air pollution. Cows share some of the responsibility for that pollution as well.
All things considered, on a world wide basis cows are a fairly minor but significant cause of pollution.

When it's very hot, I think that anything released into the air becomes a pollutant. I've heard about cows and the methane gas they produce. I live in an area that has a lot of dairies, I know they cause a lot of flies. The cars are the greatest polluters I think.

I think the Dairy and Beef Industires abusive use of cows is much more harmful than the cows themselves.

Yes accually but not of themselves in the way that as they are processed and/or used to make methane (that green house gas) it make a lot of pollution.

No, their skat does contain large amounts of methane, but it is natural. Their consumption of grass, if they are in large groups could contribute to global warming, but it is not a very big influence on our planet.

I have heard that, it is apparently due to the amount of farting they do; releases something that affects the ozone!!

No, what kind of question is that? Where do you get these ideas?
