Earth is actually in a ‘CO2 Famine’
Professor Frank J. Tipler:
“Carbon dioxide is first and foremost a plant food. In fact, plants take carbon dioxide from the atmosphere and use the energy from sunlight to combine the CO2 with water to yield glucose, the simplest sugar molecule. Carbon dioxide is also the source of all organic — this word just means “contains carbon” — molecules synthesized by plants. Without carbon dioxide in the atmosphere, there would be no organic molecules synthesized by plants. The less carbon dioxide there is in the atmosphere, the fewer organic molecules synthesized by plants. All animals depend on plants to synthesize essential organic molecules. Without the organic molecules synthesized by plants, the animal world could not exist. Without plants, there would be no biosphere.
Several million years ago, a disaster struck the terrestrial biosphere: there was a drastic reduction in the percentage of CO2 in the atmosphere.
The flowering plants evolved to be most efficient when the percentage of CO2 in the atmosphere was about 1,000 parts per million.”
“The 100 ppm carbon dioxide increase since the beginning of industrialisation has been responsible for an average increase in plant growth rate of 15% odd.”
And remember, the present level of CO2 is around 389 ppm. Which is 61 ppm BELOW the lowest figure in the video.
Also remember that commercial greenhouse operators often enrich greenhouse air with CO2 , also known as nature’s fertilizer, to levels of 1500 parts per million, or four times that of our current atmosphere.
