Verified Answer
How UV radiation is harmful to terrestrial life? It accelerates ageing...
With the depletion of ozone layer, more UV radiation filters into troposphere. UV radiations lead to ageing of skin, cataract, sunburn and skin cancer in humans.
Many phytoplankton cannot tolerate the bright, unfiltered solar radiation at the ocean’s surface and are impaired especially by the high-energy, short-wavelength radiation in the UV range of the spectrum.
UV-B impairs photosynthesis in many species. Overexposure to UV-B reduces size, productivity, and quality in many of the crop plant species. UV-B increases plants’ susceptibility to disease by sometimes causing mutations or damaging plant proteins.
