Ask HN: How can I plant more trees with technology

From past 5 years I have become forest enthusiast. Me and 5 more guys spend weekends planting trees. But it takes a lot time to plant and take care of trees. Because of our limited men-power, I fear, we won't be able to do anything impactful in our lifetime. I would love to know how technology can help in this case.

There's so much innovation happening in other fields but I can't find anything related to Afforestation. This saddens me a little bit.

I am sure there would be more people on HN who are interested in the same area. I would love to hear from you.

Any information around tooling, robotics. Any contacts, guidance. Throw any information you might think will be useful!
