"If CO2 is so bad, why do greenhouse growers pay to produce it?"

For only "pennies a day," any greenhouse owner can produce CO2 to help increase plant yields in their greenhouses. That's the message on CO2 generators sold by greenhouse supply companies across the United States and Canada. "1,500 ppm of carbon dioxide can be achieved... these generators automatically provide the carbon dioxide needed to meet maximum growing potential for only pennies a day," the ad says.

CO2 generators "improve plant quality" and "increase production." They're made in the USA and run on propane or natural gas, turning fossil fuels into carbon dioxide.

Why does this work to radically improve plant growth, health and yields? Because -- are you ready for the truth? -- CO2 is a plant NUTRIENT.

Nope, it's not a pollutant that threatens human civilization as has been ridiculously claimed by global warming doomsday pushers. CO2 actually increases plant yields, accelerates "re-greening" and improves reforestation of the planet. And while today's atmosphere contains only 400 ppm of carbon dioxide, CO2 generators can help raise that level to 1500 ppm inside greenhouses, thereby accelerating plant growth and food production.

Is CO2 is so bad for the planet, why do greenhouses pay to produce it?

If CO2 was so terrible for the planet, then installing a CO2 generator in a greenhouse would kill the plants. But scientists and even governments actually recommend supplementing CO2 in greenhouses in order to boost plant growth and food production.

"The benefits of carbon dioxide supplementation on plant growth and production within the greenhouse environment have been well understood for many years," says the Ontario Ministry of Agriculture and Food.

"CO2 increases productivity through improved plant growth and vigour. Some ways in which productivity is increased by CO2 include earlier flowering, higher fruit yields, reduced bud abortion in roses, improved stem strength and flower size. Growers should regard CO2 as a nutrient... increasing the CO2 level to 1,000 ppm will increase the photosynthesis by about 50% over ambient CO2 levels."

In fact, as recent scientific studies have shown, the slight rise in CO2 levels of the atmosphere has actually helped re-green deserts and arid areas, accelerating the growth of trees, shrubs and grasses which produce the oxygen human needs to breathe.
