As upwards of 26 billion trees are cut down every year and only 15 billion are replanted, we’re facing a deficit. As seed bombing has taken on a new meaning, airplanes are retrofitted to drop seeds instead of bombs; the potential for replantation is vast. One engineer claims to be able to replant 36,000 trees a day with the use of drones and will replant one billion trees per year at 15% the cost of hand plantation.
Lauren Fletcher, former engineer at NASA and CEO of BioCarbon Engineering, has developed drones that will carry pre-germinated seeds, dropping them in pods from 3 meters above the ground
The seeds are coated with a nutritions hydrogel, which Fetcher believes will make for much more effective seeding than traditional airborne attempts. Though it is not as effective as hand planting on a seed by seed basis, it has the capability to plant thousands of times more seeds and only needs one worker to pilot multiple drones.
