Even 200 seeds per hour would require ~145,000 participants to plant all 350M seeds in a 12 hr time frame. I’m literally just imagining a few guys with a leaf blower and a bag of seeds for how they got 350M in 12 hours haha.
I think there are a lot of countries finding out that they are not passive participants in the curve balls nature is throwing them and that they can influence what happens with simple, low tech solutions like planting trees and taking care of them and maybe a few simple changes in behavior like keeping sheep and cattle away from volatile areas.
