This will require XL pipelines from the oceans, connected to massive desalination plants. It will have to have a constant flow of fresh water to every city and town, even in the desert regions.

Yeah, okay. Meantime, please read up a bit on the issue of tipping points, and why all the climate scientists - especially those that write books - are writing (and talking) about "runaway" climate change.

He's fabulous. We need this kind of info to go VIRAL
Incredible!
He's like the Vertical Farm version of Gregg Popovich. A charismatic, wise, old man.
I had that exact thought myself, love Pop
good presentation

What if I said we don’t need to build anymore greenhouse?
There is more to it Tan what he says. I wonder what it is. He spends more time leading up to it than what it is just a stack of high tech greenhouses.
