In 1987, United Nations, through the documentation ‘Our common future’[1], known as Brundtland Report, defines the sustainable development as being to fulfill the needs of present without compromising the next generations abilities to get their own needs.” In the 2005 World Summit the United Nations, refers to the three pillars of the sustainable development as being: economic development, social development and the environmental protection.[2] Sustainable development has three basic components: the environmental sustainability, the sustainable economy and the sustainable social policy. The UNESCO World Declaration on Cultural Diversity in 2001, introduces the fourth element of the sustainable development as to be the cultural diversity”...cultural diversity it is same important to humanity as, necessary is to be the biodiversity for the nature“. So, sustainable development could involve not only the sustainable economic development objectives, but, also, objectives related to smart, emotional, spiritual satisfaction of a sustainable existence of the humankind. With this new vision, the Sustainable Development it is constructed on four pillars: economic growth, social growth, environmental protection, cultural diversity. Lester R. Brown, the father of the Eco-Economy, established 1974 the „Worldwatch Institute” which offers studies and researches, comprises in annual reports regarding the progresses made on the way to a sustainable development: „World status” or „Vital signs”. Lester R. Brown points the attention in its book „Plan B 2.0” on a real conflict generating situation, between the industrialized civilized world and the environment.

  • Tendency to end the natural resources of energy, raw materials and food
  • Higher consumption of the resources against their own regeneration capacity
  • Physical deterioration and pollution of the environmental factors: water, air, soil.  

A Sustainable Development is the one which models its economic and social system as the natural resources and the life support systems to be maintained”, concluded Lester R. Brown. In the Foreign Policy magazine, the American expert of the eco-economy, describes how “the new geo-politics of food, already started in 2011, to contribute to revolutions in various states.[3] Lester R. Brown launched in 2011, its book “World on the Edge: How to Prevent Environmental and Economic Collapse”, a manifesto on the environmental protection necessity and to the rational development in general. According to H. Vancock[4], sustainability it is a process which speaks on the sustainable development in all aspects of human life, simultaneously with gathering the economic prosperity, environmental quality, social equity, dimensions which have as vector, the technological development. The Green Development differs from Sustainable Development and it is considered to be an environmental sustainability over the economic and the cultural approaches.
