Ozone Depletion The world's ozone is depleting on a daily base. Individuals and industries are to blame. If we don't slow down what is being introduced to the atmosphere, the effects on humans and the earth will be devastating. We must stop killing the earth's ozone by watching what CFC's get released, car pooling to control automobile emissions, and stop industries from polluting our atmosphere. The problems with a depleting ozone layer are an increase in skin cancer, global warming of the earth, and a greenhouse effect on the world. Stop and look at what we can do to resolve these problems. Chorofluorocarbons (CFC's) are used today for coolants in refrigeration for air conditioning, propellants in aerosol spray cans, and as solvents in the production of electronic equipment ( CQ Researcher 303). When CFC's are released into the atmosphere, they drift upwards until they reach the ozone layer. When CFC's remain in their original molecule form they are harmless (CQ Researcher 303). When ultraviolet rays come in contact with the CFC, it breaks down the molecule part. The CFC cell attaches to the ozone layer and begins multiplying and braking down the ozone layer. Ozone destroying chemicals are extremely stable, so they last in the atmosphere for many decades. That means that if production of CFC's and halons stopped today, the chemicals already released into the atmosphere would go on destroying ozone well into the 21st century. There is an ozone hole over Antarctic, it was discovered in 1985. Since CFC's are still in air conditioners and refrigerators, releases and malfunctions from these existing units could ... ... middle of paper ... ...ugard, Paul, "ICI Regulatory Affairs Manager Clarifies Ozone, Global Warming."
