More than 15 billion trees are cut down each year: Report
Academics led by Yale School of Forestry and Environmental Studies say they have prepared the first spatially continuous map of forest tree density at a global scale, which reveals there are approximately 3.04 trillion trees worldwide.
The authors estimate that approximately 46% of the trees have been wiped out since the start of human civilization, and that 15 billion trees are cut down each year.
The report is sold for $32, and only the abstract is available free online.
