Environment-cleaning skyscraper puts a forest in the sky

This skyscraper isn't designed to hold offices or apartments. No, instead this towering monstrosity is built to undo the damage done by all the other buildings around. Think of it like a gigantic filter for the sky.

The CO2 Scraper uses trees to filter out pollutants from the air and turn them into nice, breathable oxygen. Is it the most practical idea in the world? No. But hey, desperate times call for desperate measures, I guess.
