Sustainability has now become world’s number one issue to be pursued for achieving a concrete and long lasting development. It is a process, which tells of a development, which commands all aspects of human life affecting sustenance. Sustainability means resolving the conflict between the two competing goals: the sustenance of human life and the integrity of nature. Sustainability involves the simultaneous pursuit of economic prosperity, environmental quality and social equity famously known as three bottom lines. In essence, sustainability is the ability of sustaining sustainable development, which is a process of change in which the exploitation of resources, the direction of investments, the orientation of technological development and institutional change are all in harmony and enhance both current and future potential to meet human needs and aspirations. The concept of sustainability is discussed at a time when environmental problems caused by the various human activities are requiring serious attention. Remedy lies with sustainable development, approaching the management of natural resources and the adverse effects of globalization in order to address a range of problems. In 1992, the international community as adopted at the Earth Summit in Rio de Janeiro discussed Agenda 21, the world’s plan of action for sustainable development. It was a landmark achievement, incorporating environmental, economic and social concerns into a single framework. It contains over 2,500 wide-ranging and achievable recommendations for action on issues such as, reducing wasteful use of natural resources, fighting poverty, protecting the atmosphere, oceans, animal and plant life. So sustainability is achieved when it “meets the needs of the present without compromising the ability of the future generations to meet their own needs”.
