Ozone Hole

The ozone is a layer of oxygen like gas that surrounds the earth protecting it from uv rays and other outer-space threats such as other types of radiation and or different types of solid objects. Nasa reports that the ozone layer, from September 21 to the 30th, had the largest hole ever recorded in history. The hole was a mere 10.6 million square miles in size. This hole is larger than the size of north America. The thickness of the ozone layer, in simpler terms than explained by NASA, is only about 1 cm thick. Virtually gone!!!!!! What causes this depletion???? Gases such as chlorine and bromine are to blame, says NASA. This is the reason that certain types of spray can devices have be banned in recent years. We as citizens of the earth need to think about what we are destroying, the ozone is one of the most important parts to survival of all life on earth. We need to be more conscience of what we are doing and the effects that they have on the earth and the components that make it.
