Ozone layer depletion refers to the thinning and reduction of the ozone concentration in the stratosphere, which acts as a protective shield around the Earth. The ozone layer absorbs most of the harmful ultraviolet (UV-B) radiation from the sun, preventing it from reaching the Earth’s surface. When this protective cover is damaged, more UV rays penetrate, causing harmful effects on human health, ecosystems, and the environment. _____ _____ _______ ________ __________ _____.
