We are living in the midst of a great chemical experiment, and some serious consequences are becoming apparent to scientists. More than two billion pounds of chemicals are spewed into the air each year which are brewing a disastrous stew. The greatest consequences of the atmosphere crisis may be global warming and the ozone depletion. The Earth appears to be warming due to the greenhouse effect. Scientists estimate that average temperature could climb about 2 degrees Celsius in 20 years. Global warming is the predicted result of the greenhouse effect, created by the greenhouse gases, such as carbon dioxide and methane, in the atmosphere. This change in the global climate would have disastrous results, including drought, coastal flooding and increased species extinction. Also, the scientists have discovered a hole in the ozone layer. The ozone layer is the only protection for life on Earth against deadly ultraviolet radiation from the Sun: Once the ozone layer is completely destroyed, all life on Earth will cease to exist killed by the deadly radiation: The planet will become a barren rock devoid of all life. And when this happens the process of industrialization would have to take the blame which has resulted in increased use of fossil fuels such as coal, petroleum and diesel.
