A Step in the Right Direction?

Our planet is currently in the throes of climate change. Climate change affects the world in a lot of different ways. Fortunately, becoming more environmentally conscious has helped us all.

The ozone hole that resides over the Antarctic is starting to reform. But, I can hear you asking, what does the ozone hole have to do with climate change? First of all, it’s important to know that ozone is an important gas in the atmosphere of the earth. It filters out UV light from the sun that could potentially cause cancer and other sun-related illnesses. Without this important chemical, humans, animals, and plants are at a much greater risk of receiving harmful rays from the sun. And as many people in the class probably already know, a large hole in our ozone layer has been steadily growing over the past few decades over Antarctica. And now, it is slowly starting to decrease in size.

When the UN signed into action the Montreal Protocol in 1987, it outlawed the use of chlorofluorocarbons or CFCs in industrial processes. CFCs are the major chemicals that cause the depletion of the ozone layer. According to researchers in Australia, the ozone layer is slowly starting to bounce back. This is a great thing because it shows us just how much the earth can bounce back from the damage we have caused it. We should work even harder now to continue with these positive changes. The ozone layer is expected to recover back to the state it was decades ago by the mid-century. I think that’s incredibly cool. Especially when you consider the fact that the UN calculated that “without the pact, by 2030 there would have been an extra two million skin cancer cases a year around the world.”

  1. I saw something about this recently as well! In the midst of the constant onslaught of negative news, it’s nice to know that efforts are making a difference. Even more so it shows that when we can unite to make changes, it really can work. We can put in effort as individuals as much as we want, but if we don’t find ways to make changes on a greater scale together then we might not see anymore positive change.

  2. I heard about this before in the news and its great to see that the efforts people have put to restore this important layer of the atmosphere. Hopefully in a few years, the ozone layer will no longer have a hole in it.

  3. It is definitely good news that the ozone layer has bounced back. It at least shows that there is some kind of hope for us to take care of this major problem we face. I Just really hope this is all true and the ozone layer will eventually grow back! Then we don’t have to watch another documentary of “No Impact Man”.
