While the traditional uses of drones are typically commercial or recreational, one UK-based company is using them to help the environment. BioCarbon Engineering has teamed up with drone manufacturer Parrot to create a system for autonomously planting trees to fight deforestation.
According to the World Economic Forum, the world cuts down roughly 15 billion trees but only plants 9 billion. This is in part because replanting manually is very slow and expensive. The drone-based system on the other hand is able to plant trees ten times faster than humans, for 85% less money, and in places humans can't reach.
