Environmental problems cannot be analyzed or understood if a perspective is not taken into account overall, since they arise as a result of multiple factors that interact. Our model of life an expense of natural and energy resources is increasingly growing and unsustainable. Shapes industrial mass production and consumption that make it possible to represent medium-term destruction on the planet. Some effects of the ecological crisis are already clearly discernible: increase of the temperatures, hole in the layer of ozone, desertification, accumulation of radioactive waste, extension diseases like cancer or malaria, insalubrity of the freshwater, food insecurity, depletion of non-renewable and renewable resources, etc. The waste of societies affects directly on the poverty of others and contributes to the general environmental degradation. This is known that with only 23% of the world’s population, the industrialized countries consume the 80% of the world production of commercial energy, 79% of the steel, 85% of the paper and 86% of non-ferrous metals.
Transnational corporations promote excessive growth of freight transport to distances – causing massive emissions of CO2, the construction of transport infrastructure and greater reliance on the extraction of oil resources. The widespread increase of the demands of transport is necessary to meet with major infrastructures to enable a operation of the world economy and, at the same time, fluid encourages urbanization processes and extension of the motorized mobility. In parallel with the intense growth of population, accelerating the processes of urban concentration, particularly in the countries of the South where 90% of the growth population you will have an urban character. The world’s urban population will increase from 2 billion in 1985 to 5.1 billion in 2025.
Should be taken into account that the limits of natural resources (oil, wood, minerals), (biodiversity, etc.) they indicate that the current way of life is unsustainable. Consumption in constant expansion subjected to stress the environment, emissions and waste that pollute the Earth and destroy the ecosystems. A depletion and degradation occurs in increased resources: the burning of fossil fuels is has almost fivefold from 1950; the consumption of fresh water is has almost duplicated
Since 1960; capture marina has quadrupled; wood consumption is 40% higher than what now
It was 52 years ago. Between 1960 and 2012 while the world’s population has doubled, CO2 emissions by three, the consumption of fertilizers by five and the production of energy by six. In addition, this level of consumption impact not only in nature but also in most of the people in this planet, since directly suffering the effects of this irrational model of life. Countries impoverished are not the major cause of this environmental crisis despite being places where is they produce much of the effects which, in turn, generated major migratory flows.
