Ozone Layer Depletion

The ozone layer is a natural region of ozone gas found along 9-18 miles (15-30 km) above the earth’s surface called the stratosphere. It acts like sunscreen, protecting the planet from the sun’s harmful ultraviolet (UV) radiation. Ozone depletion is defined as the gradual thinning of the ozone layer present in the lower portion of the earth’s stratosphere.
