However, optimizing the species of trees selected could boost this by 10 to 100 times. Optimizing the planting technique with drones could increase the planting speed by 150 times and cost by 10 times.
Fast growth trees would allow for lumber harvesting to repeat the sequestration every 10-30 years.”
