CO2 is Plant Food and An Essential Nutrient for Life on Earth

Posted by pwl on April 18, 2009

Everyone knows that C02 is plant food. Plants love it. They literally breath in C02 and exhale what we need to live, oxygen. Our friends the plants NEED C02!

At the current levels (just below 400 ppm) in the atmosphere plants flourish. At levels of 1,000 ppm commercial green house operators find that plants flourish even more!!!

At levels of 8,000 ppm of C02 in the atmosphere (20x the current levels in the atmosphere) humans do just fine operating the fleet of nuclear submarines of the United States of America. Yes, the sailors who can wipe out life on planet Earth live every day for months at a time submerged in a C02 rich environment making critical thinking decisions that impact us all. Without incident for decades now.

C02 is a gas that contributes to the “green house effect”. Yes, green houses benefit from this effect by upping the C02 levels and keeping temperatures warmer.

Some say that increased levels of C02 are a problem because it’s going to destroy the earth somehow.

Yet water, H2O, is the most common green house gas. The earth is covered in 70%+ with water. Since water is a much more potent green house gas shouldn’t we fear water? Many people drown each year, clearly water is dangerous. Many people are killed in floods and tsunami each year, clearly water is dangerous. By this logic water should be banned! No more water! Anything that generates water or that puts steam into the atmosphere MUST be banned! That means that clean running cars that emit water vapor must be banned since they are generating H20, a clearly dangerous green house gas!!!

Clearly all human activities that generate water must be banned!!!

Get some perspective people, especially you so called environmentalists who want to ban C02. Life is a cycle. C02 and H20 are not “evil” nor “good” they just are what they are, molecules. Clearly C02 is not dangerous in the concentrations we have in the atmosphere and it would take enormous generation of C02 to raise the levels to 1,000 ppm and beyond where plants really flourish which isn’t even in the worst case predictions of the freaked out scientists of the IPCC who are predicting doom and gloom.

C02 is essential to life on earth. Plants love it. We love plants. More C02 is better for plants which means a greener Earth!!! Different plants can take advantage of different amount of C02.

Carbon dioxide (chemical formula: CO2) is a chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure and exists in Earth’s atmosphere in this state.

Carbon dioxide is used by plants during photosynthesis to make sugars which may either be consumed again in respiration or used as the raw material to produce polysaccharides such as starch and cellulose, proteins and the wide variety of other organic compounds required for plant growth and development. It is produced during respiration by plants, and by all animals, fungi and microorganisms that depend on living and decaying plants for food, either directly or indirectly. It is, therefore, a major component of the carbon cycle. Carbon dioxide is generated as a by-product of the combustion of fossil fuels or the burning of vegetable matter, among other chemical processes. Large amounts of carbon dioxide are emitted from volcanoes and other geothermal processes such as hot springs and geysers and by the dissolution of carbonates in crustal rocks.

Carbon dioxide in the Earth’s atmosphere is currently at a globally averaged concentration of 387 ppm by volume.[1][2] Atmospheric concentrations of carbon dioxide fluctuate slightly with the change of the seasons, driven primarily by seasonal plant growth in the Northern Hemisphere. Concentrations of carbon dioxide fall during the northern spring and summer as plants consume the gas, and rise during the northern autumn and winter as plants go dormant, die and decay. Carbon dioxide is a greenhouse gas as it transmits visible light but absorbs strongly in the infrared and near-infrared.

Carbon dioxide has no liquid state at pressures below 5.1 atm. At 1 atm the gas deposits directly to a solid at temperatures below -78 °C and the solid sublimes directly to a gas above -78 °C. In its solid state, carbon dioxide is commonly called dry ice.

CO2 is an acidic oxide: an aqueous solution turns litmus from blue to pink.

CO2 is toxic in higher concentrations: 1% (10,000 ppm) will make some people feel drowsy[citation needed]. Concentrations of 7% to 10% cause dizziness, headache, visual and hearing dysfunction, and unconsciousness within a few minutes to an hour.

Plants remove carbon dioxide from the atmosphere by photosynthesis, also called carbon assimilation, which uses light energy to produce organic compounds (cellulose, lipids, and various proteins) by combining carbon dioxide and water. Free oxygen is released as gas from the decomposition of water molecules, while the hydrogen is split into its protons and electrons and used to generate chemical energy via photophosphorylation. This energy is required for the fixation of carbon dioxide in the Calvin cycle to make 3-phosphoglycerate that is used in metabolism, to construct sugars that can be used as an energy source within the plant through respiration and as the raw material for the construction of more complex organic molecules, such as polysaccharides, nucleic acids and proteins during growth.

Even when greenhouses are vented, carbon dioxide must be introduced into them to maintain plant growth, as the concentration of carbon dioxide can fall during daylight hours to as low as 200 ppm (a limit of C3 carbon fixation photosynthesis[citation needed]). Plants can grow up to 50 percent faster in concentrations of 1,000 ppm CO2 when compared with ambient conditions.[27]

Plants also emit CO2 during respiration, and so the majority of plants and algae, which use C3 photosynthesis, are only net absorbers during the day. A growing forest will absorb many tons of CO2 each year, but a mature forest will produce as much CO2 from respiration and decomposition of dead specimens (e.g. fallen branches) as is used in biosynthesis in growing plants.[28] Nevertheless, mature forests are valuable carbon sinks, helping maintain balance in the Earth’s atmosphere. Additionally, and crucially to life on earth, photosynthesis by phytoplankton consumes dissolved CO2 in the upper ocean and thereby promotes the absorption of CO2 from the atmosphere.[29]

  1. I couldn’t agree more and would only add that of all the nations in the world, only the muslim nations run on a plant food and water deficit, producing more CO2 and water per capita than any other people in the world yet consuming very little of it!!!!

    They are like the tax and spend Hussein Obama libs. Because their Souls are stained with the Black of the Demon, God has chosen not to give them any plants except for the occasional palm tree here or there, as punishment for their Demonic Faith Systems.

    Therefore, God has excluded muslims from His divine CO2 and water cycle. In return, the muslims are poisoning the planet with their excess plant food.

    Although I wouldn’t trust a muslim as far as his camel could spit, there is no doubt in my mind that this PROVES they exist to execute the Demon’s plan.

    What the FUCK RPTH?

    What a bizarre rant dude.

    First off you’re completely delusional. There is no god in objective reality, god is just an idea that’s stuck in your brain and you haven’t figured that out yet: there is no actual god, just belief stricken humans who think silly and often deadly god ideas.

    Yes the Koran might be a Demonic Faith System but no more than the Bible. In fact the Koran is based upon the Bible (read some Christopher Hitchens on that topic).

    Ah, dude, demon’s don’t exist. They are imaginary just like god.

    You’re imaginary friends are many RPTH. Seek professional help. Check yourself into a hospital.

    Souls don’t exist either dude. Another silly idea of those who can’t accept the harsh reality of Nature. We are meat driven by chemical, physical and electrical processes. That is what animates us. Stop these processes and we expire! No magical life after death. We simply stop. Death is not to be feared, but the process of death that could be painful and ok I’ll let anyone fear that, but once that’s over there is nothing not even the awareness that you’re dead. How could there be? Your brain will be dead! All electro-chemical-physical process of the brain cease means you’re toast, well dead meat, and without the brain meat and blood flowing and electricity sparking and the drug factories in your brain running your consciousness stops.

    Enjoy your life and stop attacking other people who happen to have different delusional god beliefs than you. Leave them be with their delusions. Please don’t start any wars as others likely seem intent on.

    Get yourself some professional care mr. award winning interblogger, what ever that means. You’re bizarrely warped and sick in the head dude.

    Besides your assertions about plants and muslims is not just plain wrong but immensely stupid.

    May you save yourself from your the god delusion peacefully.
