Wrong, you speak your truth, the one in your head. You don't speak about the facts. Naturally the earth has maintained an average concentration of CO2 between 180 and 280 ppm (parts per million) in the atmosphere for the last 800,000 years. http://www.sciencemag.org/content/326/5958/1394.abstract The natural CO2 has a certain ratio of isotopes which is different from the CO2 released from humans, which allows us to determine how much of the CO2 is naturally produced by the carbon cycle, and how much is from human impacts. This ratio has changed quite a bit thanks to human impacts in favour of fossil fuels. A lot of the Co2 in the atmosphere is from fossil fuels. http://www.bgc.mpg.de/service/iso_gas_lab/publications/PG_WB_IJMS.pdf As of February, the natural balance of 180 to 280 doesnt exist anymore, with the global CO2 concentration being around 400 ppm. This wouldn't be where it is if not for roughly 30 billion metric tons of CO2 being released into the atmosphere world wide. http://co2now.org http://climate.nasa.gov/400ppmquotes/ Natural sources such as volcanoes only produce up to 242 million tons of CO2 each year, which is incredibly small when compared to the 30 billion tons produced by humans each and every year. Do the math and the result is that 242 million is 0.806% of the amount of CO2 emitted by humans each year. Pretty insignificant by comparison. http://www.sciencedirect.com/science/article/pii/S092181810200070X http://www.eia.gov/totalenergy/data/annual/index.cfm Also, CO2 is good in moderation, it keeps our planet's climate at a temperature comfortable for life to exist, and it provide nutrients for some forms of life to thrive. But too much of anything is bad. You can drink too much water and die from it, you can eat too many fatty and sweet foods and die from that, you can cut yourself on class but impale yourself on a piece big enough and you die. But when it comes to CO2 feeding plants, you need to understand that plants dont survive on CO2 only, they require other nutrients in the soil, as well as water. But lets say those factors dont change, how will the CO2 increase plant growth or metabolism? Simply put, it doesn't. http://www.skepticalscience.com/co2-plant-food-advanced.htm Your comment plays by your own rules obviously, but it's not in anyway scientific or truthful. Making a claim requires one to back up the claim with credible sources, since you have failed to do so at all, it shows you dont understand science and you really dont understand the topic at hand. I'd recommend going back to school, they often do a chemistry project where you simulate a greenhouse environment, should help you understand the effect CO2 and other greenhouse gases have on our atmosphere. Good day.
