As WEF says "We are chopping down about 15 billion trees a year and planting about 9 billion. So there’s a net loss of 6 billion trees a year." But now there is a drone that can plant 100,000 a day.
Drones could fight deforestation by planting 1 billion trees a year.
This signal was also spotted by Will Dawson:
"Just watched the video for this technology. Drones are suddenly awesome worldsavers to me, rather than annoying things that fly over gardens from antisocial neighbours!"
