Ozone Layer Depletion has become one of the prevailing environmental challenges which refers as the thinning of this protective shield has raised serious concerns about rising ultraviolet (UV) radiation and its impact on human health, ecosystems, and climate. Understanding the causes and consequences of Ozone Depletion is crucial for addressing its long-term risks. This article discusses it in detail, covering its major causes, harmful effects, and the measures adopted both in India and at the global level through agreements such as the Vienna Convention, the Montreal Protocol, and the Kigali Agreement.<\/span><\/p>\n

Ozone Layer<\/b><\/h2>\n

The Ozone Layer is a protective shield of naturally occurring gas located about 10-50 km above the Earth\u2019s surface. Its primary function is to absorb harmful ultraviolet (UV) radiation, preventing it from reaching the ground. <\/span>Nearly 90% of the atmosphere\u2019s ozone lies in the stratosphere, while the remaining 10% is found in the troposphere. The stratospheric ozone is what we commonly refer to as the \u201cozone layer.\u201d<\/span><\/p>\n

The concentration of ozone is not constant; it varies by location and over different time scales, ranging from daily to seasonal. These fluctuations are influenced by stratospheric winds, chemical processes of ozone production and destruction, and natural atmospheric circulation. Due to seasonal wind patterns in the stratosphere, total ozone levels are generally lowest near the equator and highest toward the poles.<\/span><\/p>\n

Ozone Layer Depletion<\/b><\/h2>\n

Ozone Layer Depletion refers to the gradual thinning of the ozone layer present in the Earth\u2019s stratosphere. Ozone, being a thermodynamically unstable gas, readily decomposes into molecular oxygen. Under normal conditions, an equilibrium is maintained between the production and decomposition of ozone molecules. Depletion occurs when this balance is disturbed, leading to a higher rate of ozone destruction than its formation.<\/span><\/p>\n
