Ozone constitutes a very small fraction of the atmosphere, but its presence is of vital importance to life on our planet. Ozone acts as a shield protecting earth from harmful solar Ultraviolet (UV) radiation. Depletion of the Ozone layer in the atmosphere due to man-made reasons has exposed life on Earth to several types of threats. Identifying, measuring, and finding ways to mitigate these threats has engaged human endeavor for the last three decades.

To deal with this host of issues, a unique human endeavor emerged in the shape of an international protocol. An analysis of the key features of the protocol reveals the technological implications and possibilities of salvaging the planet from this environmental catastrophe. Future affects of control measures as agreed at the protocol have been studied with the help of statistical models. The projected scenario that emerges gives rise to optimism.

This ReferencePoint explains the entire gamut of issues connected with Ozone depletion, such as the causes of Ozone depletion, their fallouts, and the actions being taken to prevent the depletion.

The Science of Ozone and the Atmosphere

Ninety percent of the total Ozone in the atmosphere resides in the upper part of the atmosphere, known as the stratosphere, which is six miles above the Earth s surface. A relatively high concentration layer of Ozone contained in the stratosphere is called the Ozone layer.

The stratospheric Ozone layer provides a vital shield that protects the Earth from harmful UV radiation from the Sun. At surface level,...
