Unformatted text preview: Richard Canada Pol 223 Research Paper Most Governments want to ban CFC production but this process is expensive, difficult, and hard to persuade because a host of issues. Many countries and industries opposed the regulation of this molecule because of the costly aspects of limiting or the total prohibition of it. In the earlier stages most people didnt quite understand the science behind the production of CFC products and many still today dont exactly know what it does either. The concept of a free market always reminds me of the Adam Smith book The Wealth of Nations. In this book he explains that the invisible hand is what guides people to do whats for best for their self interest. Sometimes this can be seen as greedy but sometimes the greed can benefit society. In the case with CFCs there is no benefit to society what so ever. Before moving on to the stubborn countries and their slow regulation of CFCs lets first see what exactly CFCs are. CFC is an abbreviation for chlorofluorocarbons, which is described for a number of chemicals used in many products used. These CFCs were used in refrigerators as freon and as a propellant in spray cans. The molecule was developed as a non toxic chemical in the 1930s and appeared to be a harmless chemical. With little known of the chemical except the harmlessness of direct contact made it a selling point for the use in many household items. Today we know that ozone is directly affected by CFCs. CFCs arrive in the upper atmosphere where ultra violet radiation break the chemical apart leaving Chlorine free to attack another element to reach equilibrium. Ozone is made of O 3 which is three oxygens bonded together. Chlorine attacks O 3 and takes one oxygen away and basically destroys the ozone molecule all together. You can now imagine if many tons of CFCs are to be emitted into the upper atmosphere and what damage that can cause. Why would it take so long to regulate this problem that is a problem related to everyone in the world? Many around the world wanted to turn a blind eye to the situation or put down the facts that researchers were finding to be t rue. In 1981 there was an early detection of ozone depletion. Dobson-instrument measurements from Japanese, British and other Antarctic research stations recorded a drastic 20 percent reduction in ozone levels above Antarctica. None of the Antarctic scientists published their results or consulted other stations to confirm their observations. (Anderson) The scientists basically thought that their equipment had malfunctioned and didnt take any of the findings seriously. The Clean Air act was passed back in 1977 and still researchers and other prestigious academia were ignoring the findings of ozone depletion. Since the ozone helps with keeping ultra- violet radiation away from human interaction there is more than just global warming that could result. According to Margaret Kripke, a skin cancer expert at the M D Anderson Cancer Center at the University of Texas, told to US White...
