Skyscrapers to the rescue!

A friend sent me this story today: A different sort of skyscraper, one that cleans the environment.

The CO2 Scraper is a large-scale construction for holding between two to four hundred large-size trees that will absorb potentially dangerous pollutants and convert global warming-related CO2 (carbon dioxide) into breathable oxygen.

Designed to be placed near factories or other major sources of pollution, the CO2 Scraper is a relatively simple, primarily concrete construction in which trees would be supplied with water and nutrients via a windmill-powered pump system.

It's even designed to be energy self-sufficient! So, what do you think? Could it work?
