Half Our Trees Are Gone

Ever since the dawn of human civilization, the number of trees has declined by nearly half, a team of researchers, led by the Yale school of forestry and environmental studies, has found.

The arboreal census, published in Nature, stands at 3.04 trillion, which is 46 percent less than what it was before the advent of deforestation.

This translates, on an average, into 422 trees per person, but that varies depending on where you live. Calculations based on the latest population data indicate that the tree to person ratio is the highest in Russia, where there were 4,461 trees per person. In the U.S., there were 716. Brazil had 1,494. And India had a mere 28 trees per person.

Worse still, 15 billion trees are felled each year.
