Ultraviolet (UV) light, particularly UV-B radiation, poses harmful effects on organisms including humans due to its ability to damage DNA and cause health issues like skin cancer and cataracts.
Ultraviolet (UV) light is a type of high-energy radiation that cannot be detected by the human eye but can cause harm to organisms. UV-B light, a component of UV radiation, is particularly hazardous as it can interact with biomolecules like DNA, leading to mutations, cell death, and health issues such as skin cancer and cataracts in humans. The thinning of the ozone layer due to ozone depletion allows more UV-B to reach the Earth's surface, increasing the risks to living organisms.
