How the Ozone Layer Can Be Damaged

CFCs

     In the past century, industries around the world have grown and developed.  Some of these industries produced chemicals called cloroflourocarbons, or CFCs.  These chemicals contain chlorine, and when they are exposed to the environment, they release this stom and it attaches itself to an ozone mlecule.  When it does so, it breaks the ozone into regular oxygen.  However, when the ozone breaks apart, the chlorine is released to reattach itself to another ozone molecule and destroy it.
     Not only do industries produce such chemicals.  The exhaust from automobiles and airplanes also release destructive chemicals into our atmosphere, as well.

Natural Causes

     The ozone layer is depleted also through natural occurences.  One such cause is a volcanic eruption.  Some eruptions release hyrdrogen chloride into the atmosphere.  Much of this compound is stopped by ice paricles in the troposphere.  However, some of it does ascend into the stratosphere where it comes in contact with the ozone layer and damages it.

     Another natural cause is lightning strikes.  Whether cloud to ground, or cloud to cloud strikes, lightning causes chemical reactions in the air.  These reactions result in the break up of many ozone molecules.

     Forest fires also cause ozone depletion.  These massive fires over many acres of land release chlorine into the air which is one of the detroyers of ozone.
