The table lists down the forested areas measured in hectares in different continents for the years 1990, 2000 and 2005. Overall, forests are getting reduced in most continents with time. An exception to this is Europe and Asia. Both these regions has had an increase in forest land over the years.
In detail, in Europe, land covered in forests increases as in 1990 it is 989 million hectares, in 2000 it is 998 million hectares, and finally in 2005 it reaches an all time high of 1001 million hectares. Similarly, Asia initially had 576 million hectares of forests in 1990 and this significantly increases to 584 by 2005. Both these regions has an incredible rise in forests compared to other parts of the world.
Moreover, land covered in forests drops considerably in continents like Africa, North America, Oceania and South America. To further explain, in 1990, 946 million hectares of forests spread out in South America falls to 882 million hectares in 2005.
In summary, diverse continents on Earth are covered in varying amounts of forests and mostly the green areas decrease with increasing time.
