Greenhouse Gases Pumped Into GreenHouses

Question: What is greener than a greenhouse?
Answer: A green house that takes in CO₂ from a local factory to then turn it, naturally, into O_2.

Until recently, greenhouse's would burn natural gas for the sole purpose of generating CO₂  to feed its growing plants.

But today its being piped from nearby refineries.

"It's time we stopped thinking of CO₂ solely as a pollutant and viewed it as a valuable resource," says Gabriele Centi, a chemist at the University of Messina, Italy.

There is certainly no shortage of CO₂ to be captured and used. Around 27 billion tones are released each year through human activity. Imagine next to every smoking factory, a greenhouse that is just as large; producing just as much. NewScientist
