The first thing I think I should discuss when talking about global warming is what causes it to occur. Gases such as carbon dioxide, methane and nitrous oxide, which are known as greenhouse gases, all build up in the atmosphere of the earth. It is important to know that the "greenhouse effect" is not a bad thing in itself. In fact, this planet would be a life-less waste land without its natural green housing. Without the natural greenhouse effect, the surface temperature of our planet would be an average of zero degrees Fahrenheit. The mixture of these gases have remained pretty much stable over the centuries and have kept us all living. But here we are in the late nineties, and we are not so stable anymore. Our activities and what we use to perform our activities is increasing year-to-year, many of them doubling and tripling. It's a case of the amount of gases that Earth produces naturally vs. the amount of gases produced manually by us. Do you drive? How about using those disposable diapers that never disintegrate? Do you smoke? How about garbage or junk burning? Do you BBQ? Where do you work? Do you have an air-conditioner? Do you separate your garbage, use hair spray, spray deodorant, spray paint, flea spray, perfume, kitchen spray cleaner, bleach in your laundry, bleach in your hair, use a freezer, use an air conditioner in your car, use your fireplace, use bug spray, use lawn pesticides, ... Okay, this could go on forever. The fact is that the effects of the huge overuse of these items of luxury plus all the other items and activities play havoc on our atmosphere. We didn't worry about this 100 years ago. The reason for this is a little thing called Carbon Dioxide (CO2). The CO2 comes from fossil fuel burning (75%), land clearing & burning (25%), as well as car exhaust and coal burning. This stuff stays in the atmosphere for 50-200 years. The chemical makeup of our atmosphere and ozone is very complex. It is a combination, and interaction of the ocean, sun, land, and the biosphere. The greenhouse gases work to trap the heat producing energy on our Earth, and pretty much does a good job of it if left undisturbed. We have disturbed it. The human production of greenhouse gas producing chemicals is what is disturbing it. This production by humans of these particular gases linger in our atmosphere for
