  1. 1. DEFORESTATION Work made by: Catarina Silva 9ªA Nª6
  2. 2. Deforestation • One of the biggest factor of deforestation is the Human being! • Forests cover 31% of the land area on our planet. They produce vital oxygen and provide homes for people and wildlife. But forests around the world are under threat from deforestation, jeopardizing these benefits.This impacts people’s livelihoods and threatens a wide range of plant and animal species. Some 46-58 thousand square miles of forest are lost each year—equivalent to 36 football fields every minute.
  3. 3. • Deforestation is a particular concern in tropical rainforests because these forests are home to much of the world’s biodiversity. For example, in the Amazon around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching. Deforestation in this region is particularly rampant near more populated areas, roads and rivers, but even remote areas have been encroached upon when valuable mahogany, gold and oil are discovered.
  4. 4. News: Deforestation in Amazon • The deforestation in Amazon raise 28% between August of 2012 and July of 2013. In that period were destroyed 5843 km2 of forest, the equivalent of about 600 football field. • Greenpeace exists because this fragile earth deserves a voice. It needs solutions. It needs change. It needs action. Greenpeace
  5. 5. Causes • Deforestation can happen quickly, such as when a fire sweeps through the landscape or the forest is clear-cut to make way for an oil palm plantation. It can also happen gradually as a result of ongoing forest degradation as temperatures rise due to climate change caused by human activity. While deforestation appears to be on the decline in some countries, it remains disturbingly high in others and a grave threat to our world’s most valuable forests still remains.
  6. 6. • ILLEGAL LOGGING National laws regulate the production and trade of timber products at all stages, from harvesting to processing to sales. • FIRES Fires are a natural and beneficial element of many forest landscapes, but they are problematic when they occur in the wrong place, at the wrong frequency or at the wrong severity. • FUELWOOD HARVESTING Wood is still a popular fuel choice for cooking and heating around the world, and about half of the illegal removal of timber from forests is thought to be for use as fuelwood.
