Hole in the Ozone is a documentary film that educates its audience the relationship of ozone and chlorofluorocarbons (CFCs) and its effects to our atmosphere. Hole in the Ozone also known as Ozone Depletion or Ozone Thinning had been an issue since the 70s and 80s. Even until now, this has become one of our major environmental issues. It is surprising to know that the ozone performs a major part in protecting us from dangerous radiation that the sun emits to our planet, even though it is also part of our pollution. As discussed in the film, the atmosphere is divided into several layers by density and temperature. In the second layer of the atmosphere, there lies our good ozone. I never knew that ozone is being build up in that layer, wherein it continues to be broken apart when struck be the sun’s radiation and combined again. As the process is being repeated, the ozone layer absorbs most of the solar radiation. But as they say, too much of everything is bad. The ozone could no longer fully protect us because as the solar radiation comes in and destroys the ozone compound, human activities in the earth also cause its depletion. Chlorofluorocarbons had been developed in the 30’s. This was even considered as a perfect compound because of its perfect qualities: non-toxic, non-flammable, non-corrosive, and non-reactant. But then, scientists started to suspect this perfect compound, and later discovered that the compound is being piled up in the troposphere and is destroyed in the stratosphere. It was intriguing to know that once this compound is destroyed, it produces chlorine atoms that kill the ozone. And the scary thing I learned too is that CFC lives up 75-100 years, takes 25 years to rise in the stratosphere, and worst of all, the CFCs effect we are experiencing now are the ones which were accumulated in the past. I hope this will be put to an end or we will suffer more in the future with life-threatening diseases like cancer.
