Why are the ozone holes located in the Arctic region?

The ozone hole is a region of low ozone concentration that forms over the Antarctic during the austral spring and summer. It is caused by air pollution from human activities, such as burning fossil fuels. This causes an increase in the amount of UV radiation reaching the Earth's surface. Ozone absorbs UV light, which can damage plants and animals, so when there is less ozone in the atmosphere, more UV radiation reaches the surface.
