Why are we concerned?We should be concerned because research confirms that high levels of UV rays cause non melanoma skin cancer and it also plays a major role in malignant melanoma development. UV is linked to cataracts or medical condition in which the lens of the eye becomes progressively opaque, resulting in blurred vision due to exposure of UVR and impaired immune system.

In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone. There is so much oxygen in our atmosphere, that these high-energy ultraviolet rays are completely absorbed in the stratosphere.
