Why is depletion of ozone layer a cause of concern ?
Answer
The ozone layer shields the Earth from harmful UV radiation; its depletion lets more UV reach the Earth, harming organisms.
The ozone layer high up in the atmosphere shields the surface of the Earth from the harmful ultraviolet (UV) radiation of the Sun. When the layer is depleted, more UV radiation reaches the Earth, and this radiation is highly damaging to living organisms — for example, it can cause skin cancer in human beings. So the depletion of the ozone layer is a cause of concern.
