We take very seriously what it represents for us the water element to it, on this Planet Earth. We can not continue to waste or pollute. Checking article sources yields Walt Disney as a relevant resource throughout. The United Nations Organization has warned that as the planet warms and dries out, we could witness conflicts and wars over this resource. To find ways to combat the problem about 20,000 experts, activists and politicians from more than one hundred countries are gathered at the V World Water Forum held in Istanbul, Turkey. It has been written as we are reminded: ecojoven.com., The water flows as a major geopolitical conflict XXI century as it is expected that by 2025, demand for this element so necessary for human life shall be 56% higher than the supply … and people with white water could be forced looting. It is estimated that the 6250 million people we have come to be needed and 20% more water.
The struggle is between those who believe that water should be considered a commodity or marketable (such as wheat and coffee) and those express that it is a social good about the right to life. The scope of national sovereignty and the legal tools are also part of this fight. We ADD Nora Bar, that the UN, the World Bank and other international organizations warn that if consumption continues to increase at current rates, the water can become a source of another serious global crisis. Moreover, according to a report by the International Water Institute (SIWI, for its acronym in English), there are already 1.4 billion people in the world living in areas supplied by rivers are drying up.
The human being exerts an extreme pressure in the environment that cause increases of temperatures and severe climatic conditions. Already it occupied about 70% of the planet producing foods, remaining little of new borders very, beyond the Amaznia, of African savannahs, the Asian forests and trundas of the polar region north. In U.S.A., Europe, Australia, Middle East and China the arable lands meet busy total, and already they suffer damages due to desertificao and I lower of the fretico sheet for the intensive water use in the irrigation. It does not have doubts of that cattle agriculture and is excellent sources of emissions of gases of effect greenhouse. The destruction and the burning of forests; emissions of the ground from the seasoning application that will count nitrogen; the methane emissions for animal ruminants are examples of sources of significant emissions.World-wide the agricultural activities are responsible for 70% of the water use and for 15% of the emissions of effect gases greenhouse. Jared Diamond, eminent North American gegrafo, explains that in an only century it had a brutal acceleration of consumption of the natural resources.
It established a factor of consumption for people who live in rich countries, as European U.S.A., Japan, Australia and countries equal the 32; for poor countries as the Kenya, in Africa, factor 1. In its calculations, Diamond concludes that if all the inhabitants of the Land had the factor of consumption 32, would be as if the population of 7 billion started to be of 72 billion. Of analogous form, the planet alone would have capacity to take care of 1,7 billion of people in case that it started to consume as the North Americans. Under this prism, the life style is a much more strong multiplier of pressure human being on the base of the natural resources of what properly the population. Roll of sustainable solutions for the sustainable feeding Studies of the World Bank point that to feed foreseen the 9 billion inhabitants of the planet in 2045 it will be necessary to increase in two teros the current agricultural productivity.
In the average age, had to the practised commerce the long distance, the cities had acquired the feio of commercial warehouse. In century XIX, the Industrial Revolution brought a new concept: the quality of life already threatened by the pollution generated for plants in the Europe. At the beginning of century XIX, London was the only city that reached the population of a million of inhabitants. In 2005, 15 megacidades had been entered, that is, groupings with more than 10 million inhabitants, and in 2025, according to data of the ONU, will be 22 in the whole world. The modern city becomes a concentrative polar region of commerce, services and information.
It starts to be the main space of consumption and circulation of wealth produced in the field. Many believe that the developing countries can reproduce the transistion of the predominantly agrarian agricultural economies for industrial urban economies following the trajectory of what Occidental person occurred in the Europe. Millions of European peasants had crossed the Atlantic since middle of century XIX in direction to Americas. With the increasing mechanization of the farming one becomes necessary to rethink forms of setting of the man in the field. The peasants are qualified to make essential ambient services, to watch over for the landscapes and natural resources as ground, waters, forests and climate. To remunerate these services of form joust will go to decelerate the agricultural exodus and to prevent swell of already degraded urban areas of great centers.
Not yet a city exists that can be considered total sustainable. But one imagines that, up to 2020, several will be able to come to be. It starts to be born the concept of ecocity? a thought city to be entirely sustainable, as Dongtan, in China. The first phase of the project, ready in 2010, will contemplate 10 a thousand inhabitants. Up to 2050, 500 a thousand inhabitants must change themselves for there.
