The average surface temperature on Earth has increased approximately 1.0°F in the past century, and it is projected that it will again increase somewhere two and nine degrees by the year 2100. This is the expected effect of increased greenhouse gases, which contain the Sun's energy (heat) in the lower atmosphere (troposphere). Much of the increase in these gases can be considered a natural occurrence, however, at least some of it is human induced. The depletion of the ozone (O3) layer is negatively affecting our ecosystem, by way of global warming and climate change.

Some of the benefits of the O3 layer in the stratosphere (outer layer of the Earth's atmosphere) are: that it provides us with blue skies; it protects man and vegetation from the harmful ultraviolet (UV) rays of the sun, and traps the proper amount of heat within the Earth's atmosphere to sustain life. While O...
