Some numbers: forests Tropical rainforests occupy about 6% of the total area of \u200b\u200bland where some 50% of all species. Today deforestation at a rate fast: within fifty years, these areas may no longer exist, if nothing is done about it.
But how deforestation happens in reality? Let's see what happens in Brazil.
The forest is allocated to small farmers, who shall be able to burn it to grow, the crops may continue for 2, maximum 3 years. Because of a combination of important factors (limited thickness of the tropical soil, abundant rainfall and high evaporation), the completely loses the soil humus, and therefore its fertility and become totally unproductive. These areas are so impoverished in the hands of ranchers, exploiting what little is left. The end point of the big industries are mining, which they build their plants when the areas have become veritable deserts.
It has a certain effect in Brazil think that 1% of farmers (ricchi!) owns 43% of cultivated land. The poorest are left of the actual plots of land: in short these are a Asorti of "slaves loggers" in the service of the richest and most powerful.
I invite you to take a look to the Amazon Rainforest Google Earth. Look Rondonia, Brazil, and you realize that what you feel is not false alarms. Think that once was all green. Now there are those lines that cut through the forest roads are. And those parallel branches that depart from these streets, on both sides (which seem to
fishbone) are nothing but the future directions of deforestation. Streets of destruction.
