What are the causes and effects of ozone layer depletion?

Short answer: Decreasing ozone means increases in melanoma (skin cancer), cataracts, famine (loss of arable land, and damage to crops). This would only occur in areas that had this thinning or hole in the ozone. Tanning therefore, would not be recommended in the Antarctic r Arctic during the winter months.

This might not be a good idea for other, more pressing reasons such as frostbite More detail Earth's surface receives more UV-B, as ozone is the only gas currently in our atmosphere that absorbs UV-B. UV-B is also absorbed by soil, meters depth of water, and directly by the DNA of all surface life. DNA absorbing UV-B ends up increasing rates of cancer, mutation, and decreases crop yields UV-B also causes cataracts to form in eye structures in animals (including Man) Ozone interacts to some small extent with infrared, so it also is a greenhouse gas... which moderates day-night temperature swings.So thinner ozone will allow the high temperatures to be a little higher, and the low temperatures to be a little lower Earth is not in danger of losing its ozone If the ozone layer entirely disappeared, and there were oxygen left anywhere, ozone would form (at least) at lower altitudes.

The amount of dangerous UV that got through would increase, but not to the levels incident from the Sun. The issue would resove itself in a matter of days. Oxygen, combined with sunlight causes ozone.

This is why we have no thinning or "hole" in areas that always receive sunlight because of this harmful UV rays of the sun can reach the Earth unfiltered. This causes severe problems like skin cancer, cataract it causes plastic to become brittle and affects crop yields negatively at both poles See What are the causes and effects of ozone layer depletion? Additional_information: Additional information: The thinning areas known as holes only occur in the two polar regions and only during their winter months.

We know that this thinning is primarily (and possibly completely) caused by the lack of sun. It is very true that during these periods you would possibly increase your risk of contracting melanoma should you decide to tan in the Antarctic during these winter months. I would suggest not doing so for other reasons No thinning of the ozone layer has been observed beyond these two locations and only during their winter months.

The largest known thinning occurred in 1858, before man started using CFC's and was caused by solar activity.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
