The devastating turn of events from environmental factors to scientific ones is whether major or minor surely affects “planet earth” unconditionally. Does it ring a bell through contamination, pollution and vast destructions?  Drawing near mass destruction is not really very far though. Imagine living in deplorable conditions where the basic necessity of life is deprived. All caused mainly due to human activities that contaminating the earth environment? Delving into this issue has made researchers come up with various explanations. Materials that interfere with the normal functioning of the ecosystem, the quality of human life and health caused either by natural or human activities is called pollution or contamination of the earth’s environment. These are caused by polluting materials or pollutants, which has a hazardous effect on both nature and human life. Pollutants are of two types.

  1. Degradable pollutants – materials such as sewage that rapidly decompose by natural processes.
  2. Non-degradable pollutants - materials that do not decompose or either decomposes very slowly in the natural environment.

Contamination of the earth can be determined by various factors. One such essential factor, which plays a key role in environmental contamination, is the various chemicals exhibited in different forms such as exhausts from automobiles and photochemical smog, which has been a continuous threat to human life and threatens to wipe away the face of the earth in quick duration. The effects are large and one such effect, which is partly based upon, is ozone depletion and global warming.

“Temperatures in the Arctic winter lower stratosphere are generally close to the threshold for substantial chlorine activation, making Arctic ozone particularly sensitive to small changes in temperature”

 These controversial headlines which seemingly keep coming has sent the world into a frenzy of inexorable curiosity. So what is ozone depletion? What are its causes and the effects on human life?

The Earth's atmosphere is divided into several layers. Most atmospheric ozone is concentrated in a layer in the stratosphere, about 15-30 kilometers above the Earth's surface. The ozone layer absorbs a portion of the radiation from the sun, preventing it from reaching the planet's surface. Most importantly, it absorbs the portion of ultraviolet light ...
