Vehicles are considered *non-point source* pollution because they are mobile. You have different pollutants coming from diesel vs. unleaded engines. Factories (I'm assuming all types of them, not just car factories) are *point sources*. Depending on what they make depends on the type of pollution. Some of the big players are *coal-fired power plants*, which put out *NOx, CO2, and mercury* among others. Your bigger city areas that have *"ozone watch days"* are usually in *non-attainment* counties. They usually have high traffic and congested motorways. *Non-attainment* counties are determined by the EPA through various methods of testing and an *8-hour determination*. Look up any of those *starred* terms at www.EPA.gov for your answers. Other types of industries to look at when talking about air, ground, and water pollution are (all starred in this list) *thermoset resin/reinforced plastics (fiberglass - like boat mfg.), power plants, mining operations, metal finishers, foundries, dry cleaners*. Go to www.sblga.info for a list of industries that the EPA regulates to see what kinds of small-business sources there are and the types of regulations that they have to follow. That 800 number at the top is also very helpful, no matter where you live. But to answer your basic question, the EPA regulates US-based industry so that there are not any serious health effects from their processes. In the past, we have recognized that the pollutants that we put out can harm humans and the environment, so that's why laws are passed to stop them from doing that. Since the industrial revolution, mankind's endeavors have brought about harmful consequences to the world. We are all responsible for protecting the environment and it's inhabitants. A good book to read about it is "Silent Spring" by Rachael Carson. Good luck on your research, hope you get an A+!

pollutants emitted by cars and factories are destroying the ozone layer in the atmosphere, causing the greenhouse effect.
