Or better ... How much is the Earth? Imagine that the Earth is sold at a handful of real estate agents brothers ET, are based on what price to decide what is the Earth? Each Tecnocasa good employee knows that there are criteria on which to set the price for a property now, even if the Earth is at a standstill (as someone we wanted to believe), we think Constance and other scholars to answer this question.
Costanza and others have studied the various ecosystems and biomes, then they have multiplied the value that came out for this to their full extent and have them combined. From this it turned out that the Earth moves "a production well U.S. $ 16-56 trillion (10 to the twelfth!) A year, with an average of U.S. $ 33 trillion per year . Everything in front of a world GDP of about U.S. $ 18 trillion annual .
were based on " services" that the various terrestrial ecosystems play in the Earth and that the man advantage entering their economy. These services vary in size and there are also included raw materials produced, these are designed as a service to humanity. Some examples, of particular interest to the present day I can be: the ability to accumulate waste, the ability to absorb CO2; defense against devastating events ... There are so many categories, even 17, many of which are services that the self-reinforcing system. A special feature of this study is that weighs only renewable resources, non-renewable resources are not even considered. So even renewable resources are renewable little? Yes, if an ecosystem too stressed here that this not be repeated.
Constance also wonders what the service is most important, and which of these if there is no longer harmful. It turns out that is by far the most important, with an order of magnitude above the others, " soil formation." And this is true, because there will be no soil any ecosystem, and without any other ecosystem service of man. Then the worst news we hear on the news should be the degradation of soils by human activities ...
