Sustainable is a word that qualifies the non Development, is not quantifiable The concept proposed by the UN, by its specific forums, and later by the Conference of Rio de Janeiro (Rio-92), is considered one of the concepts, but not the only one. The World Commission on Environment and Development, created in 1983, emphasizes that "Sustainable development is the one that meets the needs of the present without compromising the ability of future generations to meet their own needs".
The concept of sustainable development for environmentalists is an old aspiration to determine their needs and priorities of the new society, a new ethic of human behavior and a restoration of the primacy of social interests, collective.
The environmentalists' position is seen as a change of the production and consumption in the context of reversing caused environmental degradation and social misery. This concept of environmental degradation would be adulterated as it is interpreted by different social actors, to be perceived either as port of entry for international mechanisms of control over our natural time as a strategy of expansion and market profit.
An ecologically sustainable society is one that:
a) Conserves biodiversity and life support systems;
b) Ensures that the use of renewable resources is sustainable and that the degradation of non-renewable resources is minimized;
c) Seeks to remain within the capacity of supporting ecosystems.
In 1972 the Club of Rome entitled "Limits to Growth" focuses on examining how the development and retain their destruction to the environment.
There is no development in itself, but a society that opts for development that you need and want. If a company is sustainable, by definition, it is said that a sustainable society where to the satisfaction of their needs, without compromising the natural capital and without prejudicing the right of future generations to see also met their needs and they can inherit a planet healthy ecosystems with their preserved.
This, suggests that the sustainable society produce enough for themselves and for the beings of the ecosystems where it is, taking only what nature can replace it, and that in practice the company must show itself capable of assuming new habits and design a type of development that the growing attention to the ecological balance and function within the limits imposed by nature.
The obsolescence must be contained, not necessarily prevent the consumption but the irresponsible consumption.
To be sustainable, development must take into account social and ecological factor, as well as economic, the bases of living resources and non-living, the benefits of alternative actions, I the long and short term. The development is an economic, social, cultural and political comprehensive task, aimed to constantly improve the welfare of the whole population and every person on the basis of their active participation, free and meaningful and fair distribution of benefits from it.
From a more practical way one can say that the social development aims to improve the quality of human life as human, this includes long and healthy life, education, political participation, social and participatory democracy and not representative, to ensure the respect for human rights and protection against violence, conditions for a proper spiritual and symbolic expression.
These transformations lead to the implementation of various barriers such as differences between the conviviality, warmth in social relationships, and compassion with the next in miserable situations or marginalized, the creation of compensatory measures and social inclusion. Principles of sustainability of the Earth:
a) Build a sustainable society;
b) Respect and care for the community of living beings;
c) Improve the quality of human life;
d) Maintain the vitality and diversity of the Earth;
e) Remain within the limits of the capacity to support the planet Earth;
f) Change personal attitudes and practices;
g) Enable the communities take care of their own the environment;
h) Create a national structure for integrating development and conservation;
i) Form a global alliance.
Sustainability refers to the need to expand the capacity of the Earth's resources, and creativity through the use of technology, to limit the consumption of fossil fuels, renewable and non renewable resources, to reduce the volume of waste and pollution through conservation energy, resources and policy, to promote the self in consumption of materials from the rich and poor countries and to intensify the search to obtain technology for low-waste and efficient use of resources for development urban, rural and industrial, in addition to defining the appropriate standards for environmental protection.
Sustainability Space is addressed from the reduction of excessive concentration in metropolitan areas, curb the destruction of fragile ecosystems, promote agriculture and farm forestry using modern techniques, regenerative, for small farmers; explore the potential of decentralized industrialization, coupled with new generation of clean technologies, and create a network of nature reserves and biosphere, to protect biodiversity.
In relation to environmental awareness, it would seek sustainable development, a vision that for conscious would learn to grow with the premise the care of the environment that you live.
Any development would only be valid when first worry about all the interventions and consequences to the environment before moving forward to be considered.
