In simple terms, sustainable development (SD) refers to maintaining development over time. However, there are more than three hundred definitions of SD in the literature. Although the concept of sustainability is not new, it is the political and economic context in which it is applied that defines its saliency.
The idea of sustainable development encapsulates the reduction of vulnerability of the human condition, poverty and welfare issues, social justice, and environmental protection, as well as economic growth and equitable distribution of its gains.For SD to be meaningful it must encompass all issues about science, innovation, technology, research and development, information technology and e-commerce, economic development, health, Foreign Direct Investment, Multinational Corporations, international debt, aid, trade, politics, war, natural disasters, population growth, terrorism and so forth. The responsibility for achieving sustainable development is global and rests on both the developed and the developing nations. Therefore, we must think globally but act locally. We must also ensure that we pass on to future generation at least as much environmental wealth as we inherited.
