Definition Of Ozone Depletion

The earth is made up of layers like the troposphere, stratosphere, and ionosphere. The troposphere is the closest layer to the earth and the one that humans are closest to. The troposphere has the purest form of atmosphere that can sustain life and also maintain the environmental balance. The stratosphere is the layer that houses the ozone layer, and it is somewhere above 10 kilometers to 50 kilometers in range.

What Causes Pollution ?

When pollutants enter the environment, be it water, soil, atmosphere or water, and end up making the environment unsuitable for living organisms, then it is termed as pollution. Chemicals, heat, light, noise, smoke and fumes are all pollutants. Sometimes, some pollutants like heavy metals are naturally present in the environment but in low levels.
