ozone depletion In this world of rapid change, it’s extremely difficult for a company to stay ahead of the game even using all the resources available to them. So, it’s difficult to imagine the problems they would run into when a group of environmentalists decide to boycott a substance which is the foundation of their company. These chemicals, although very useful, cause consequences that need to be dealt with now in order to prevent further damage. The chemicals in question are numerous, but the two gaining the most attention are chlorofluorocarbons (CFC’s) and carbon tetrachloride.
CFC’s have a wide range of uses, but are popularly used in aerosol propellants and air conditioning for homes and cars (Singer and Crandall ng).
Carbon tetrachloride is one of the major components in making CFC so their damage is similar. When they inter the outer atmosphere, They react with ozone chemicals to release chlorine and bromine that in turn deteriorate the ozone and form ‘thinning’ or ” holes.’ This is catastrophic because they are bonded very strongly together and cannot be broken down by water. This means they travel into the atmosphere virtually unharmed by rain or decomposition (Goldfarb 282).
The reason these are causing such a commotion is the damage they cause to living things on Earth. When the ozone depletes, it causes more ultraviolet (UV) rays to hit the Earth’s surface than are healthy (Singer and Crandall ng).
... for the phase out of production and importation of ozone depleting chemicals. The EPA established various policies such as refrigerant recycling ... air conditioning units must pass an EPA-approved CFC recycling course. CFC-12 used in motor vehicles was phased out ... looking for in the form of two compounds: dichlorodifluoromethane (CFC-12) and (CFC-11). In both compounds, different amounts of chlorine ...
UV rays affect the DNA of every living cell, altering the protein make-up of that cell (Goldfarb 288).
Most importantly it affects ” which rest at the bottom of the food chain, placing us in extreme danger (Goldfarb 288).
Henry Lee, leading researcher on ozone depletion for the Environmental Protection Agency (EPA), says that UV rays will only have a slight effect on oceans, though. He says the problem lies on the fact that 70 percent of the Earth’s surface is covered with water, making it a widespread problem.
In addition to that, humans exposed to excess UV rays over a period of time are likely to develop some form of cancer (Singer and Crandall ng).
The EPA released a report that stated if CFC’s weren’t controlled, in the future there will be approximately ’40 million additional cases of non-melanoma skin cancer found and 800, 000 additional skin cancer deaths’ (Singer and Crandall ng).
Now that scientists know what these and other ‘culprits’ do, they ” retrying to find solutions to this world-wide problem. When they found these chemicals to be harmful, environmentalists didn’t hesitate in taking action. They placed a boycott on the use of aerosol spray cans.
The U. S. and Canada responded by banning ‘CFC powered spray cans,’ and that, along with Europe agreeing to cut back by 35 percent, caused the rate of damage to fall drastically (Singer and Crandall ng).
Therefore, manufacturers have to stop using these. The only other alternative is to find replacements for these deadly compounds. This is easier and more practical than stopping production altogether.
It costs millions of dollars to re-tool manufacturers’ machines, while losing money in the process. DuPont is the largest producer of CFC’s and stands to lose the most if and when a ban is placed on CFC’s. Because of this position, they ” re stepping up research on chemicals that get the job done, but cause less damage (Singer and Crandall ng).
Hydroflurocarbons (HFC’s) are ” made with hydrogen instead of chlorine,’ which doesn’t contribute to the ozone problem, but is a factor to the greenhouse effect (Goldfarb 290).
... and the world better place. Destruction of ozone layer is a serious problem that individuals should solve. No matter how much ... exceed any other field. However, individuals can resourcefully solve this problem. Rafic Hariri, a Lebanese politician, delved into the unemployment ... depressed ,even they start blaming government. There are many problems that leads to affect our community either directly or ...
Hydrochloroflurocarbons (HCFC’s), like HFC’s, have hydrogen in place of the deadly chlorine, but still contribute to ozone depletion. The only difference being HCFC’s deplete at a much slower rate (Goldfarb 290).
The major breakthrough is the discovery of CFC-134 a, It’s also chlorine-free but deteriorates before it reaches the outer atmosphere, so no damage is done. I twill take the place of CFC-11 and CFC-12 in some refrigeration and coolant products (Singer and Crandall ng).
Many people are surprised to see the government moving so quickly in regards to this major problem. One writer said it was hard enough to get lawmakers to agree on anything, but in this situation, they ” re ‘moving with unusual speed and resolve’ (‘Ozone Defense’ 63).
Which doesn’t excuse the fact that when they knew CFC’s and tetrachloride were harmful they should have put an immediate freeze on production of them. One scientist commented by saying,’ …
absolute proof is not needed when we are conducting an experiment on our own planet’ (Goldfarb 291).
Regardless of what happened in the past, we should be thankful they moved as quickly as they did. In doing so, They bought us some much needed time in this race for worldwide safety.
