Respond to the following question:
What specifically is causing the hole in the ozone layer? Why is it not getting smaller?

Your response should be thoughtful and well-written at be at least 5 sentences.  Your entry should not be the same as your classmates.

  1. The hole in the ozone layer is being caused by the depletion in the ozone layer above Antarctica. The ozone layer is in place to shield the earth from harmful ultraviolet radiation that leads to skin cancer in addition to damaging our trees and plants. The hole is not getting smaller because humans continue to pollute the environment. Human made compounds that are particularly destructive because of the way in which they release chlorine and bromine gas into the stratosphere. We need to reduce our pollution dramatically if we want to reduce the hole in our ozone layer and create a healthier environment.

  2. The ozone layer is being depleted because of high levels of chlorine and bromide in the stratosphere. The ozone layer depletes the most during August and September in the Southern Hemisphere. This occurs because there ware higher levels of Bromide and Chlorine during this season. Unfortunately, humans are the ones producing these molecules that are ripping holes in the stratosphere. If we lose more ozone more UV radiation will occur and then there will be more cases of skin cancer throughout the world.

  3. Ozone depletion is mainly generated by human-made compounds that release chlorine and bromine gases in the stratosphere. The size of the ozone hole will likely increase the number of UV rays , especially in the Southern Hemisphere in the near future. Unfortunately, an increase in UV rays means an increase in various health related issues, such as skin cancer, suppressing immune systems, and even harming plants. Humans are the cause of this hole because of the release of chlorine and bromine gases in the stratosphere. If we don't do anything to further prevent this, we are looking at more cases of skin cancer.

  4. Ozone is being destroyed by chemical reactions with chlorine and bromine in the stratosphere. These chemicals were released into the atmosphere by products that used them as refrigerants and fire suppression. In 1987 an international agreement limiting the use of theses chemicals took effect and the amount of the chlorine and bromine in the atmosphere have begun to decline. Until the chemicals are cleared from the atmosphere they will continue to break down the Ozone creating the hole in the ozone layer. This won't happen until after 2070 when the ozone hole will return to 1980 levels.

  7. The ozone is being depleted because of chemical reactions with chlorine and bromine in the atmosphere. These reactions are occurring because of humans releasing the chemicals in the air. With the hole in the ozone increasing the amount of UV rays will increase as well. The hole is not getting smaller because we are still releasing chemicals in the air. If we do not change the hole will continue to get bigger and the heath risks that it will bring are unmatched to anything we have ever encountered.

  8. The ozone is being destroyed due to human pollution. These pollutants are Chloride and Bromide. These pollutants are released in the form of collants and fire supresents and if we use less of these polluttants their will be less wholes in the ozone. If we can reduce the size of the landfills than these dangerous chemicals will not be able to spread.

  9. One thing that is causing the hole in the ozone layer is cold temperature and hot dynamics. Additionally, the high levels of chemically active of chlorine and bromine further increase the size of these holes. These molecules come from man made chemicals, which have increased over the years. The reason why the hole is not getting smaller is because people continue pollute and are not aware of this issue. If we do not resolve this problem quickly, the amount of skin cancer cases will increase significantly in the coming years.

  10. The ozone is being destroyed by the high levels of chlorine and bromide in the stratosphere. This is mainly caused by humans and can be reduced so that there will be fewer holes in the ozone. If we get rid of most of the large landfills then we can stop the release of chlorine and bromide. There is an increasing amount of UV rays going through the Ozone which makes it more dangerous to go outside in the sun because those harmful rays are going through. This is why we need to cut down on the amount emission.

  11. The ozone has grown so much since last year. The ozone is still growing right now, and the ozone keeps us safe from UV rays. When the UV rays get into contact with your skin you will start to get skin cancer. So protecting the ozone layer is very important to everyone on earth.

  12. The hole in the ozone is occurring because of human made compounds that release chlorine and bromine gases in the stratosphere. Therefore humans have the responsibility to reduce emissions. However, the size of the ozone is supposed to reach the size it was in 1980 by 2070, but until then humans are at risk of being affected by ultraviolet rays. This can cause skin cancer. Everyone should do their part to reduce emissions so that risk is not as high.

  13. The release of Cl and Br is the direct cause of ozone's depletion. The whole is not becoming smaller or staying its current size due to mankind's constant pollution to the earth. Some of the most common uses of man contributes continuously to the problem. And this problem isnt to be fixed until 2070, but by then couldn't the damage already be too late to fix?

  14. The hole in the ozone is caused by human made compounds that are releasing abnormal amounts of chlorine and bromine. The human race is to be held responsible for the hole in the ozone. The only way we stop the ozone hole from enlarging is to cut down on emissions. It will be tough but we have little time left if we want to reverse the damage that we have dealt to the environment.

  15. the ozone is becoming depleted due to man made compunds and activities. The burning of fossil fuels and so forth. It is not shrinking because our usage of these acts are not shrinking.
