Answer» Solution :Ozone depletion: Ozone presnent in troposphere contributes to GREEN house effect. Ozone PRESENT in stratosphere PLAYS a vital role in protecting the life on earth's surface from harmful UV radiations. Ozone layer acts as a shiled as ABSORBS harmful UV radiations. Pollutants such as `CFC_(s)` when reach stratosphere react with zozone and thus depletes the ozone layer in a period of time. Hence, UV radiations reach tropospheric layer due to the holes created in zozone and affect plant and animal life. PREVENTION: Discovery of alternative substance for `CFC_(s)` used in refrigeration and aerosols. |
