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. These chemicals are brewing a disastrous stew, resulting in an atmosphere crisis. The greatest consequences of the atmosphere crisis may be global warming and ozone depletion. If humankind wants to continue to inhabit earth, then we must stop this horrid destruction of our own environment.

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. This change in the global climate would have disastrous results, including drought, coastal

Global warming will have wide spread impacts on health, economics, politics, and the environment. A warmer climate will actually increase crop yields and open more land to farming in upper latitude countries like U.S., Canada, and Russia, but for the poor countries of equatorial Africa, Asia, and South America, crop yields will most likely decline. That is because many crops currently grown there will not be able to tolerate the additional heat. In addition, these countries are also burdened with the highest rates of population growth on the planet. So, there will be less food in exactly the places where food supplies are needed most. Changing sea levels and precipitation patterns could also affect health. Ironically, as the sea levels rise, the water many people depend on for drinking and sanitation may become scarce or of poorer quality. Rising sea water levels would send salty water farther up rivers.

Every spring, scientists announce the dimensions of the year?s ozone hole over Antarctica. Currently, about 80% of the ozone layer disappeared from an area centered on Antarctica that was nearly the size of North America. This time of the year, however, it?s the Northern Hemisphere that commands most attention. Ozone loss peaks during fall, when the Earth?s angle of orbit to the sun puts the Northern Hemisphere almost directly in the path of the sun?s deadliest radiation, which
