What have you read or know about “ozone holes” in the atmosphere? Why do they arise and how can they affect human health?

Ozone hole – a local drop in ozone concentration in the ozone layer of the Earth. As a result of the lack of solar radiation during polar nights, ozone is not generated. No ultraviolet light – no ozone. The weakening of the base layer increases the flow of solar radiation to the Earth and causes an increase in the number of skin cancers in humans. Also, the increased level of radiation leads to a sharp increase in mortality among marine animals and plants.
