Which is the True Price of a Tree?

Escrito el 25 agosto 2009 por Jesus Guerro en General

arbolOver times trees have removed countless amounts of atmospheric carbon dioxide, the principal cause of the greenhouse effect today we face. 10,000 years ago forests occupied more than 6,000 million hectares of the Herat Surface. Today, forests occupy only 4,000 million. Between 1950 and 1980 the area covered by forests decreased by 25%. In some places, deforestation is carried out at breakneck speed. As examples, in California, urban trees die or are eliminated four times faster than are replaced. Each year 11 million hectares are destroyed, with some countries like Nigeria, which were large exporters of wood, and now are importers. A significant loss of forests directly affects other life forms through the atmosphere. By consuming CO2, the trees mitigate the greenhouse effect. Each mature tree consumes, on average, 6 kilograms of carbon dioxide a year. When the trees of a forest die naturally and are felled responsibly, to be replaced by other trees, there is no net loss of oxygen in the atmosphere. But when cutting or forest is burned, it loses most of the oxygen. Thus, forests that are removed suposes to increase 25% of global CO2 emissions each year. In cities, groups of urban trees cool the air up to 10 degrees and reduce energy demand for air conditioning by 50%.
So What is the true price of a tree? Does the value of 1 ton of paper? Does the value of 2 tonnes of wood? Is that, the correct criteria to measure? Today no doubt

But think for a second how much money it would cost to create a machine like an oak that was capable of generating the oxygen consumed by 10 people or neutralize the CO2 emitted by each car runing 1 hour. Consider also that machine was also capable of bearing fruits like, apples, cherries, oranges .. and of serving food to hundreds of species, and all without consuming any mililittre of fuel.

So What is the true value of a tree?
