摘要: Due to the decrease in quantity of total-column ozone stratosphere—which we call hole—lesser solar UV-B radiation (290–320 nm) is absorbed, resulting greater fluxes it reaching earth’s surface. As most energetic component sunlight that strikes surface, can have profound effects on humans, other animals, plants, microorganisms, materials, and air quality. The obvious questions arise are following: What consequences depletion nature intensity ultraviolet its biotic abiotic components ecosystems? important effects, what be done prevent or mitigate them?
