Drones that can plant trees and save the world

A UK-based startup company called BioCarbon Engineering is trying to use drones in order to plant trees in areas that have been deforested. With the help of drones and 3D Mapping, planting trees would be a cheaper, faster, and more efficient.

How it works?
A Drone will fly in a deforested area, conduct surveys, and construct detailed 3D maps of that area. Then, drones will fly in and sow seeds in the area. According to the company, the drones can plant 36,000 seeds a day which is 85% more efficient than the traditional hand planting method.
