“On Feb. 2, 2007, the United Nations scientific panel studying climate change declared that the evidence of a warming trend is "unequivocal," and that human activity has "very likely" been the driving force in that change over the last 50 years. The last report by the group, the Intergovernmental Panel on Climate Change, in 2001, had found that humanity had "likely" played a role.” (Science, 24 March 2009).

Global Warming, Acid Rain and the depletion of the ozone layer will heavily affect the life of human beings; the depletion of the ozone layer will make human beings more vulnerable to skin cancer. The flora and fauna will inevitably get affected because of all the above concerns. Acid rain is acidic in nature and any rain which consists of unusual amounts of acid can be called as acidic rain. The main cause of acidic rain is the emission of nitrogen and sulfur; this is because of the human activities. There have been many laws introduced by the government to keep a check on human activities which trigger off acidic rain. Acidic rain is believed to have devastating impact on aquatic life, animals, and most importantly on the health of human beings.

“The ozone layer protects the Earth from the ultraviolet rays sent down by the sun.  If the ozone layer is depleted by human action, the effects on the planet could be catastrophic. Ozone is present in the stratosphere.  The stratosphere reaches 30 miles above the Earth, and at the very top it contains ozone.  The sun’s rays are absorbed by the ozone in the stratosphere and thus do not reach the Earth.” (Ozone Depletion, 24 March 2009). The ozone layer is instrumental in protecting the animals as well as the human beings and its depletion has been constantly on the rise which not good news for the human beings. The production of the chlorofluorocarbons is the biggest cause of the depletion of the ozone layer. This chemical is very valuable for the countries which use it and they don’t want to stop the production of this chemical, this can spell danger and can easily disturb the balance of the Earth. The climate of the Earth is constantly getting affected by the depletion of the ozone layer and it is high time to take appropriate measures to deal with the same.
