Surprisingly, when all the facts are in, CO2 is beneficial! It is an essential trace gas, and a fertilizer. The current increase has boosted growth rates of vegetation worldwide by 13 to 15% (see here). CO2 is used as a supplement in greenhouses. In a closed greenhouse, growth slows or stops if the plants use it up and CO2 drops below 200 ppm as the plants absorb it.
