Ozone Depletion In The Stratosphere

Explanation

Ozone Depletion in the Stratosphere

The Earth's ozone layer protects all life from the sun's destructive radiation, yet human activities have harmed this shield. Less ozone-layer protection from bright (UV) light will, after some time, harm crops and lead to a surge in skin cancer cases and cataract cases.

Introduction

The Earth's atmosphere is made up of several layers. The lowest layer is the troposphere that extends from the Earth's surface up to around 6 miles or 10 kilometres (km) in vertical height. Almost all human activities happen in the troposphere. Mt. Everest, the tallest mountain on Earth, is just about 5.6 miles (9 km) high. The following layer, the stratosphere, extends from about 10km to about 50km in elevation. The commercial airlines fly in the lower stratosphere region.
