• As for how many trees are cut down each year, the 2005 report concludes that primary forest area (as opposed to plantations)was reduced globally by 60,000 square kilometers per year (about the size of Ireland. Note that this data is incomplete due to a lack of available data from many countries who do not monitor such change. As to the “number of trees” this represents, it’s impossible to get an accurate count. Tree density in primary forests varies from 50,000-100,000 trees per square km, so the math would put this number at 3 billion to 6 billion trees per year.

nearly 50000 species become extinct. About 2.7million acre lush, fertile cropland
