FORESTS

• Forests cover almost one-third of the earth's
  land surface the global area of forest systems
  has been reduced by one half over the past three
  centuries

• Worldwide, the total forest area in 2005 is just
  under 4 billion hectares the rate of
  deforestation is about 13 million hectares per
  year. The net change in forest area in the
  period 2000-2005 is estimated at -7.3 million
  hectares/year

• Tropical forests are home to about 50 of all
  plant and animal species on the planet

• Approximately 1.5 billion tonnes of wood is
  harvested for fuel annually worldwide

• Forests are among the most notable storehouses
  of biological diversity on the land - they house
  over two-thirds of known terrestrial species
  they also harbour the largest share of threatened
  species

These images show deforestation rates in the
area, believed to be one of the highest in the
world

  images is the result of extensive deforestation
  and intensive cultivation
