Natural resources are limited, whether as a non-renewable or renewable. Planet Earth has a natural capacity and it is a given for the human community. The current pace of development of the world economy and the accelerated population growth threaten to soon lead to exhaustion of nonrenewable energy resources and to exceed the speed of regeneration of renewable resources (water, energy, food) and thus lead into questioning the survival of human communities and future generations. Only through the application of the principles of sustainable development (sustainable use of resources) and implementation of logic of survival can a safe and steady growth be followed and present and future needs catered to [1].
