Our problem with the greenhouse effect is plain and simple. In 1994 the United States emitted about one fifth of the total greenhouse gases into the atmosphere. As a result of the industrial revolution and the burning of fossil fuels in addition the abundance of cars, mining, deforestation, as well as population increase, the atmospheric concentration of greenhouse gases are increasing very fast. Yearly, industrial factories are responsible for about 80% of society carbon dioxide emission, and about 25% of methane and 20% of nitrous oxide.
