IS there any way to protect the ozone layer?Farere66 - 6 Answers
Not only can we protect the ozone layer, it's being done. The story is one of humankind's greatest achievements, and a good example of what can be accomplished when people and governments heed the warnings of scientists.
The ozone layer high above the earth is a shield from harmful radiation from the sun. In the 1970's, scientists began to notice that the ozone layer was thinning, and gaps in the shield were growing to sizes never seen before. The 'ozone hole' that opened naturally at the poles was stretched and getting bigger each year, letting cancer causing radiation to reach large populations around the world.
They found the culprit to be a class of compounds widely in use - chlorofluorocarbons, or CFC's. They were being used in refrigerators, spray cans, lubricants, and many other commercial products. The CFC's, scientists warned, were destroying the ozone layer, and if they continued to be used, irreversible global damage would result.
The world responded, slowly at first. Several countries banned the use of CFC's as propellants in the 1970's. However, CFC use actually grew. And by the 1980's it was clear the ozone shield was in serious trouble. An international convention in 1985 drew up plans for governments to reduce the use of CFC's by half within 15 years. A second convention in Montreal in 1987, passed an international Protocol to cut CFC use.
But by 1992, it was clear, these measures weren't enough - ozone depletion was growing. As the scientists' warnings grew stronger, there were loud objections from industry and skeptics. They claimed the ozone hole was a natural phenomenon and not man-made; that it was a conspiracy and a hoax; and that governments had no right to regulate free trade. Billions and billions of dollars of commerce and profits would be lost. Refrigeration manufacturers warned there were no commercial substitutes to CFC's, and no one would be able to make ice.
Despite these objections, the world's governments decided to regulate an end to the production of CFC's. In the United States, these regulations and their enforcement were managed by the Environmental Protection Agency (EPA).
These efforts were a tremendous success. As a result of these global regulations over the commercial production and use of ozone damaging products and compounds, the destruction of the ozone layer has been stopped, and is reversing. Based on current measurements, it will return to it's natural strength within about 50 years.
Ozone layer is needed to be protected severely.The ozone hole causes skin and eye problem.Many old architecture sites of the world are considerably affected by ozone layer.
Ozone hole is caused by the emission of chlorofluorocarbon and nitric oxide in environment.To protect it we should reduce pollution and try to develop the habit of recycling.Use environment friendly vehicles and try to use cycle for little works.
The most simple way to protect the ozone layer is afforestation, although it is a slow and steady process. Reducing the release of ozone reactive gaseous elements like Chlorofluorocarbons into the atmosphere is another way to protect the depletion of the ozone layer....
Another remedy here . If scientist can find a solution that has no effect on our oxygen or nitrogen , a solution that natural elevates sealing,repair or replacing our already damaged ozone layer ! Just a thought...
Yes, we need to reduce pollution and harmful gases released by factories and cars for example. But it really has to be a global effort....
Needs to stop launching jets which release Nitrus Oxide and Nitric Oxide. CFC should not be used as a cooler.
