If you've finished marvelling, I remember something my esteemed co-blogger once said when irked by some whining about the depletion of the Amazon rainforest. "Fuck it. If we wanted to, we could just build another one."
I know this artificial leaf doesn't create oxygen, but I suspect that's just a matter of time.
