Survey questions: Sun seekers!?

The depletion of the ozone layer is the main reason for the increase in the number of cases of skin cancer. CFC’s have been banned in Canada. Considering this, do you think that the number of cases of skin cancer will decrease in the near future? Do you believe it is safe for people to "seek" the sun?





I am conducting a survey for our school project. So it would be very helpful if you provide me with your educational level, experience, background and age.

Survey questions: Sun seekers!?
The links between the release of CFCs into the atmosphere and the most serious concern, an increase in the incidence of skin cancer, particularly malignant melanoma, are as follows:





1. CFCs, with lifetimes of decades and longer, become well-mixed in the atmosphere, percolate into the stratosphere, and release chlorine.


2. Chlorine destroys ozone catalytically, and thereby lowers the total amount of ozone in the stratosphere.


3. A reduction in the ozone layer results in an increase in ultraviolet radiation reaching the earth's surface.


4. Exposure to more solar UV radiation leads to a huge increase in skin cancer rates and hundreds of thousands of additional deaths.





Each of these steps is controversial, has not been sufficiently substantiated, and may even be incorrect.

Good Luck with your project.
