We have learned it in school – CO2 is good for plants. Thats why operators of greenhouses often feed additional CO2 into their glasshouses. They know that more CO2 means healthier and stronger plants and that their nutritional value also goes up very significantly. CO2 is not the molecule of destruction – it is more like a molecule of life. And the levels we detect today are pretty close to the level where plants die. We need more CO2, not less.
“overall, elevated CO2 provoked changes in the phytochemical contents of caraway plants, particularly at the sprouting stage and, hence, improved their nutritive and health-promoting properties.”
