The Ozone Hole
- Details
- Category: Combat O3 Depletion
The concentration of ozone (O3) in the upper atmosphere has been depleting since 1980's; some of the UV can reach the surface of the earth and cause damages of health to human and animals. The articles attached below state the current status (2011) of the ozone layer. Although, the ozone "hole" is healing up by itself, it is so huge (10.05 million square mile, compare to the area of USA, approx. 3.79 million square miles or 9.83 million km2) and the rate of decay of the CFC is so slow (half life of some of the CFC are approximately from few years to over one hundred years) that there is nothing we can do but wait? If we choose to wait, the duration could take more than a century, can we do something to speed it up?
