Desarrollo Sostenible

S and called sustainable development that can meet current needs without compromising the resources and ability of future generations. Intuitively a sustainable activity is one that can be maintained. For example, cutting trees in a forest restocking ensuring it is sustainable. In contrast, oil consumption is not sustainable with current knowledge, since no known system for creating oil from biomass. Today we know that a good part of human activities are not sustainable in the medium and long term as we now are raised.

This definition is the report of the Brundtland Commission . Mrs. Brundtland is the prime minister of Norway and in 1990 was commissioned by the UN to write a first report to prepare the Summit of Earth's Rio de Janeiro two years later.

H ay Other definitions are also interesting as the one proposed D. Pearce, A. Markandya and EB Barbier , which states that a sustainable society should not have:

• decline unreasonable use of any variant
• significant damage to natural systems
• significant decline in social stability

Another definition is due to H. Daly . This person suggested that a sustainable society is one in which:

• resources should not be used at a faster rate than its rate of regeneration,
• not issued pollutants faster than the natural system can absorb or neutralize,
• non-renewable resources should be used at a rate lower than the human capital created to replace lost natural capital. Specifying this definition in a practical case, the fossil fuel, it means you have to use part of the energy released to create energy-saving systems or systems to enable the use of renewable energy to provide the same amount of energy the fossil fuel consumed.

are three ways to define sustainable development. The first is the simplest, certainly that has been more successful, while the second and third are complicated reasoning.

Keep in mind that is a strategic definition of conceptual and globalized, and there is a marked difficulty in translating it into everyday life. However, we must make an effort to overcome the practical difficulties involved in the ecological principle of think globally and act locally.

MAIN CHALLENGES OF SUSTAINABLE DEVELOPMENT

L to inability of the human species to live in harmony with the planet, the strong interaction between man and the natural system, certain environmental problems are great today. To this day, no species, except man, has managed to change so substantially in such a short time, the characteristics of the planet.

Thus, the major global issues arising following:

• Overpopulation and inequalities
• The greenhouse effect
• Destruction of the ozone layer
• landscape Humanization
• Preservation of biodiversity
• erosion, desertification and forest destruction

and local :

• The production system
• water
• household waste
• energy supply
• transport system
