Some already pointed out, I am also curious about sustainability and how many trees will survive in future BUT I am incredibly amazed of the number of trees planted in just 12 hours. I might be naive in this thinking but it gives me hope about what we can achieve once we have to.

See church forests in Ethiopia. These are just lands that were fenced off from grazing, and they look like random oases in the desert. So clearly trees can survive in the general area.

Thanks. They look amazing.

> Deforestation became rampant when the land was nationalized in 1974 and much of the forests became converted to farmland. only the 5% survives.

It seems that Brazil is in the way to become the new Etiophia... and that for some reason chopping the forest lead to water saying bye-bye and welcoming hard, regular and extensive famines.

Not a direct answerto your question, but we can be sure that 100% of trees not planted won't be there in the future.

I agree. Though even if a fraction of the trees survive in a place of harsh conditions, further generations of the same seed can carry the same strength and spread.

That’s something I witnessed myself from my village years.

If we want to, we can automate this. https://www.fastcompany.com/40450262/these-tree-planting-dro... talks about a company (https://www.biocarbonengineering.com/) that uses drones to map out a planting area and then precision plant 100,000 treelings in a day.

I have planted trees in my younger days. A thousand seedlings are extremely cheap to buy, but brutal to plant. The work in the hot Sun, at least in Florida, is a rough day.

Have you any good reason to not doing it at night? Headlamps are affordable, caffe is easy to find and is also better for watering and reducing the humidity shock in the tender roots.

Trees will plant themselves.

The idea that humans have to intervene in nature is part of the problem that brought us to this place!
