environmental crisis: a series of problems that have led to a critical stress due to technological and industrial progress developed outside natural systems.

different alternatives to environmental problems

"Uncontrolled exploitation

Is a direct result of industrialization and overexploitation of resources provova the current environmental crisis. It is based on the generation of wealth and consumer goods that promote economic growth or economic development without taking into account the deterioration of the natural, ie based on the consideration of the economic system outside of the ecological system. Its features are:

  • inflows is matter and unlimited fossil fuels.
  • believes that technological advances will solve future problems.
  • ignores hidden costs or inputs such as environmental impacts, generating large amounts of waste, high energy consumption involved, pollution, etc.
  • invariably leads to depletion of the natural system that maintains and economic collapse.

inputs hidden costs: environmental costs are not usually contablizar in the price of the products and have adverse effects on the environment, health or society.

Emerged in the 1972 Stockholm Conference as a result of making
awareness of the serious environmental problems facing the planet. We propose
industrialized countries are aware that these problems threaten
health and the falsity of two ideas that have guided development:

  • The omnipotence of man
  • nature is indestructible

The developing countries that want to reach the living standards of the others do not accept
that conservatism is the solution, since it implies that they are in a position
clearly at a disadvantage both socially and economically.

-Sustainable Development
Was coined in the Brundtland Report, 1987. Is defined as economic activity that meets the needs of the generation
present without compromising the ability of future generations to meet their own needs. Defend:

  • Economic development of all nations (solidarity between generations)
  • Care of the environment for future generations (intergenerational solidarity)

Sustainability be achieved at three levels:

  • Economic
  • Ecological
  • Social

The idea was embodied in the 1992 Rio Summit on the Earth Charter and the document
called Agenda 21 which sets out the overall management strategies necessary to
achieve the objectives in the present century.

The principles of sustainable development are:
Principle of sustainable harvesting (potentially renewable resources): the rate of consumption of that resource must be equal or less than the renewal fee.
Principle of sustainable discharge (non-renewable resources) emptied their consumption rate must be equal to or less than the rate of creation of new renewable resources to replace them when they run out.
Principle of sustainable emission: the emission rate of pollutants must be below the assimilative capacity of natural or recycled conducted themselves from the environment
Principle of sustainable selection of technologies: encouraging the use of new cleaner and more efficient technologies.

Zero irreversibility principle: proceed with caution so as to reduce to zero the environmental impacts that may cause irreversible damage to the environment

Principle of equitable development (social sustainability): quality of life equal to all the inhabitants of
