OK class, today we will be speaking about ozone depletion. Can anyone tell me what that is? Jhonny?
Ozone depletion is the gradual thinning of the amount of ozone in the stratosphere.
Spot on! Now, ozone depletion is caused by chlorofluorocarbons, or CFCs, which are a man-made group of compounds that are released into the atmosphere. They are the main cause of ozone layer depletion.
CFC's contain chlorine, fluorine, and carbon, and chlorine is the main element that destroys most of the ozone layer. It combines with one free oxygen to create two oxygen molecules, and after that reaction, it begins to interact with an ozone molecule. With each reaction, the ozone layer continues to brack down and recede. How do you think this affects us and the environment?
Cl + O3 -> ClO + O2 ClO + O -> Cl + O2 O3 + O -> 2O2
Ozone depletion can cause skin cancer, sunburn, wrinkles, and sun spots. Ozone depletion affects amphibian species in the ways in which their behavior and habits change, and their immunity decreases as well. Amphibians can also experience deformities.
You are absolutely correct! Alright, we have 3 minutes before class ends so I would just like to tell you all some things you could do to help decrease ozone depletion. The main thing that we can do to help our environment, is to stop making CFC's and other chemicals, as well as spread the word. Other than that, I wish you all a wonderful rest of the day and I'll see you tomorrow!
