Seriously, rich people, get out of your own bubble heads now and then.
A low-tech, low-resource-intensive, no-dependency application of this technology has huge applications around the world.

>Why the need to have people hike out just to launch the seed bombs.
Because re-wilding requires a hands-on approach to be very effective. Just look at what China has done with the Great Green Wall - this was a labor intensive mega-project. Low-tech, highly effective solutions for seed distribution could be of great benefit in that context - without a bit of fancy speculation on our part, we'd still just have deserts and nothing to eat.
YES, you could 'just use a helicopter'. You could just sit back on your deck chair and be served mocktails, too.

Do you know how easy and cheap it is to make gunpowder?
I was making black powder rockets from grocery store ingredients when I was 12.
