Forests, besides being home to many indigenous peoples, hosting the two-thirds of Earth's biodiversity. It is, therefore, clear that, alter or destroy them, it threatens the survival of millions of plant and animal species.
managed sustainably, provide timber and other forest products and are the basis for maintaining the environment, prevent erosion and regulate the hydrological cycle. And no less important in the fight against global warming. According to a study published in the journal Nature, is an important carbon sink. The authors of this work, "an international team of scientists, concluded that the northern hemisphere forests retain up to 10% net carbon dioxide (CO2) absorbed in the world. Therefore, if these forested areas are destroyed, would release the CO2. Which means more global warming, more destruction of forests, which in turn leads to more climate change.
A recent study by the Center for International Forestry Research (CIFOR in English Silgan) argues that, if not immediate action, climate change could destroy large forest areas, affecting biodiversity and human populations that depend on them.
WHY ARE FORESTS DISAPPEARING?
Experts say various causes of the disappearance of forests than anyone else but stand to the timber industry, which Logging these forests to produce paper or replaced by fast-growing plantations to meet the demand for turpentine. For example, Greenpeace claims that 17% of the virgin fiber used by the global paper industry comes from forests virgins, especially from Canada, Finland, Russia and Indonesia. It also claims that Europe has a domestic market directly responsible for the destructive and illegal logging in countries like Indonesia, Brazil and Cameroon.
Meanwhile, WWF says that in the past decade, natural forests were destroyed to convert them into plantations agricultural and forestry at a rate of 16.1 million hectares per year: 94% occurred in the tropics.
must be added the mining and oil, construction of dams and roads, the agricultural and livestock expansion, introduction of invasive species, forest fires, biofuel crops, the fragmentation of ecosystems, and air pollution.
The World Watch Institute notes that over 75% of the world's primary forests, is in three main areas: Canada and Alaska, Russia, the Amazon and Guyana. In the case of Europe is only 0.3 of the original forest in Sweden and Finland, in large continuous areas.
Greenpeace lists the seven last great forests of the world:
• The Amazon rainforest
• The Southeast Asian jungle
• The rainforests of Central Africa
• The temperate forests of South America
• Primary forests of North America
• Europe's last ancient forests and
• The forests of the Siberian taiga
each year is estimated to be lost or modified some 6 million hectares. Primary forests of 76 countries have completely disappeared, while 11 are on the verge of doing so.
This entry is related to the previous. Never in any of my blogs have been treated any topic related to politics but of course I have my opinions. I thought they were so many fundamental reasons trying to defend the Indians of the Peruvian Amazon, the situation that had been swept away by trying to defend its survival, was one of those in the know and remain silent are just as guilty as the very evil that has befallen them to silence and submission. Have returned to negotiations with the government of Alan Garcia, have confidence that the reason is hit once more to satiate the insatiable, to justify all the abuses in the holy name of development. It may not be necessary to add that anyone who grows, enriches and develops are not precisely the rightful owners of wealth.
