An estimated 15 billion trees are cut down each year—more than 41 million per day. Given this pace of land degradation, it’s hard to imagine how traditional reforestation methods, which rely on the hand-planting of live seedlings, could ever keep up. BioCarbon Engineering offers another way—a device, no more than two feet in height, that has the potential to plant 400,000 seeds per day—150 times faster than hand-planting carried out by a human.
