What is ozone and how does it affect any ecosystem?

Explanation

Ozone is a form of oxygen. A molecule of ozone contains three oxygen atoms `(O_(3))`. In the stratosphere, ozone layer comprises high concentration of ozone some 18-50 km above. Here, it is being photo- dissociated and generated by the absorption of harmful, short wavelength UV radiations. By absorbing harmful UV radiations, this layer protects all forms of life on earth.
Certain harmful chemicals such as chlorofluorocarbons (CFCs) methane `(CH_(4))`, oxides of nitrogen (NOx), etc., produced by human activities are thinning the ozone blanket. As a result, more UV radiations penetrate ozone blanket to strike the earth and producing skin cancer, damage to eyes including increased incidence of cataract and damage to immune system of human beings and other animals. These also result in increased embryonic mortality, decreased photosynthesis in plants and contribute towards global warming.
