It doesn't, exactly.
The issue is not so much pollution in general as carbon dioxide specifically.
Carbon dioxide is what's called a "greenhouse gas" because it tends to trap heat. If the concentration of carbon dioxide in the atmosphere goes up significantly, more heat is trapped, meaning the temperature goes up.
Some other pollutants are also greenhouse gases, but not all of them, and not all pollution generally.
The controversy over global warming is not about whether or not this happens... no one who knows anything at all about the subject seriously doubts that it happens. The disagreement is to what extent it happens, and whether or not the warming trend seen is a) an actual trend rather than simply random chance, and b) caused by humans as opposed to being a natural variation.
Wolves pollute nothing. They only give to the Earth. Humans are the one's who pollute everything. >:<

We pollute the Earth and then from that pollution (such as coal, fuel, gasses, etc a layer forms on the Earth. We use fuel, we pollute more (did you cows also have a MAJOR part in this part) etc and it nothing can escape from from the atmosphere because of that layer of pollution so the Earth gets warm. And since nothing can escape its still building up and getting worse.
it can on burning!
