...if we ripped up all the concrete and buildings to replant a forest...

You say this like it's a downside, we'd better get started!

Hey, I'd be the first wanker with a sledge out breaking it up if we all went in on it together. Something tells me I wouldn't get very far tho

It would be. Cities and urban areas aren't the problem. Suburbs, with 20+ Minute commutes, on hot swollen rivers of concrete and asphalt flowing from them, with every individual in their own metal/polymer box burning hydrocarbons is the bigger problem. Cities might be a solution.

Conversely these algae tanks can go lots of places a tree wouldn't be practical. They'll never need to be trimmed out of power lines etc. Or tear up sidewalks, streets or foundations. That's not to say we shouldn't have trees. Just more green overall.
