Atmosphere crisis
Atmosphere crisisWe 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 the greenhouse effect( global warming) and the ozone deletion. If humankind wants to survive well into the next millennium, than 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 flooding and increased species extinction. And, 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.
Global warming is the predicted result of the greenhouse effect, created by so-called greenhouse gases, such as carbon dioxide and methane, in the atmosphere. The increase in these gases is thought to be caused by industrialization, especially by the use of fossil fuels such as coal and oil. These gases act much like the glass in the greenhouse: They let sunlight in and keep the heat from escaping. As these gases increase in our atmosphere, concern has grown that temperatures will increase around the globe, just as in the inside of a greenhouse. 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...
