The Sustainable Forestry Initiative recently set a world record by organizing one of the largest tree-planting events ever. On May 20, 2015, volunteers planted more than 200,000 trees at 28 sites, spanning from New York City to Vancouver Island, British Columbia. More than 1000 volunteers worked in groups of 25-100 to accomplish this daunting feat.
