Given the recent census which claims some 3,000,000,000,000+ trees world-wide, this rate would equate to an overall population increase of ~0.001% per year (less, if were counting total biomass), and that only if the rest of the world maintained an even balance which, sadly-yet-unsurprisingly it does not, resulting in the net LOSS of about 10,000,000,000 trees world-wide (~0.3%) every year despite the U.S. effort.
