Could plastic trees end air pollution?

Forests and oceans naturally take carbon out of the air, but CNN's Rachel Crane finds engineers are trying to copy Mother Nature's work.

Plastic! Where has common sense gone! Just stop cutting down rain forests and start planting real trees

[hueyfreeman]

Why don't they plant more trees??? the many, the better, LITERALLY

[Mannard]

How about for starters you stop spraying us with coal fly ash????

We are all at the mercy of corporate greed. They have us by the balls with material and monetary love.

THIS just proves how artificial CNN really is ;)

[AmericaTheEnslaved]

isn't that the job of real trees?

[Smegma]

The title is highly misleading. Besides, plastic trees would be oil-based, thus defeating the purpose...

Someone clearly never watched the Lorax

TTFD! I grow trees and your geo-engineering is killing them. Please stop.

then what's the point of making this video???

[bige-zlou]

Hmmm! I think I got it! Less carbon dioxide(humans) - trees + plastic trees + fans = sustainable development (new world order). Now, if only Mr. Wizards World could have figured that one out back in the day, we wouldn't have global warming/climate change.
