Citizens of developed countries have become accustomed to a comfortable lifestyle. In recent history, humanity has become aware of the consequences of this way of life in terms of physical impact on planet Earth and in terms of social impacts on future generations. The idea that our species is negatively impacting the world has sparked concerns about whether human life will indefinitely be able to enjoy the comfortable lifestyle experienced by people in developed countries. It is alarming that the Earth's population continues to grow and more and more citizens continually have access to the unsustainable lifestyles of today's generation. According to Robert Engelman, president of the Worldwatch Institute, the energy and food of the future. The United Nations, a globally recognized authority on environmentalism and humanism, defines it as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” This certainly implies that sustainable development can only be achieved by ensuring that future generations can enjoy the same standard of living as modern citizens of developed countries enjoy. As a result, sustainable development cannot be achieved by permanently depleting resources to meet the needs of the current generation – there must be a loop through which the current generation can maintain the condition of the Earth, so as to preserve it indefinitely. Continually depleting resources is a practice that defies this definition, because the Earth does not have an infinite capacity for superfluous materials. Sustainable development is systematically described as a convolution of three pillars: economic, social and environmental. Ideally, effective sustainable development should result in improving all three aspects. Ban Ki-moon, the current Secretary-General of the United Nations, clarifies these pillars and adds a fourth in this remarkable quote: “Sustainable development is the path to the future we want for all. It provides a framework for generating economic growth, achieving social justice, exercising environmental stewardship and strengthening governance.” Making positive changes in sustainability is difficult because it requires taking all of these pillars into account. The ideal solution, while respecting sustainability, must be economically viable, protect the environment from damage and improve the quality of life. It follows that sustainable development, by its nature, is an endeavor that will require international effort and collaboration,
