INTRODUCTION Protection of environment or in other words environment preservations or preventing environment pollution has been a growing concern of the modern times. As time flies by‚ and with the theory of global warming and other environmental issues coming into action‚ protecting the environment is of utmost significance. Every nation has its duty towards protecting their surrounding environment. Protecting environment has become such an issue that nowadays; the perspective of protecting has

important issue in our lives. We have come to realise that the modern ways of man place an enormous amount of stress on the Earth that nature simply can’t handle. Some of the climatic problems that are developing today‚ such as global warming‚ ozone depletion and El Nino‚ will have severe effects on our ecosystem. The world is warming up. As we burn up the planet’s coal‚ oil and gas reserves‚ and cut down its remaining forests‚ greenhouse gases are pouring into the atmosphere. The delicate balance

The Foundation of Society: A Review of Social Contract Theory The Social Contract Theory works as a rule of moral constraints in society for the common good. For Rachels’ perspective‚ “The Social Contract Theory: The right thing to do is to follow the rules that rational‚ self-interested people would agree to follow for their mutual benefit.” (Rachels 158) Based on “self-interested” criteria‚ people “need another enforceable agreement” to last harmonies which are built on this social contract.

at the time. These chemicals had been accumulating in the atmosphere for many years‚ but had not been thought to be causing any harm. However‚ Molina and Rowland proved this was wrong with their "CFC-ozone depletion theory." This theory stated that the CFCs in the air were actually destroying the ozone layer that protects the earth from dangerous ultra-violet rays from the sun. Molina and Rowland published their findings and informed the media‚ as well as lawmakers of the potential dangers of CFC

Issues such as global warming‚ depletion of the ozone layer‚ land degradation‚ etc. are all cause of over-negligence of the environment by we humans. Today‚ there is greater need to bring our focus back on our environment and to make every small effort to save it from depleting and getting
