Plants use CO2 for photosynthesis to create sugars to build plant tissues. Elevating CO2 level increases the ability of cannabis plants to manufacture these sugars. Cannabis growers can virtually double harvest yield using CO2 atmosphere enrichment.
CO2 is calculated and measured in parts per million (ppm). Country air contains about 300 ppm. Most researchers think the optimum level to maximize cannabis growth rates is about 1500 ppm. This is about five times the concentration of CO2 currently found in the earth's atmosphere. Cannabis can absorb up to 6 times the current atmospheric concentration of CO2 while putting out corresponding amounts of Oxygen.
Genetic mutations are random but the selection of advantageous traits is completely dependent on the environment and totally non-random. Cannabis is the result of cumulative non-random adaptations to environmental forces over millions of years. This capability suggests cannabis and other plants have survived other epochs of climate change and carried with them the seeds for our collective survival.
It is true there are other plants which grow well in similarly high CO2 levels but cannabis is the only one which can do this while providing non-toxic medicine, remediating soil pollution, reducing soil erosion, providing bountiful harvests of seeds rich in Omega 3 and 6, providing fiber for hempcrete and hemp plastics in addition to providing biomass fuel for energy needs. There is no other seed which can be grown on every continent that would be as immediately and gratefully planted by a majority of the world's population as would cannabis.
Imagine how little this will cost compared to ANY alternatives and how enormous we should consider the economic value of our collective physical survival. Think of how incredibly effective this method would be compared with other totally ineffective and very expensive solutions oil companies keep trying to sell us. Even wind turbines and solar panels require facilities' to be built and comparatively large amounts of capital investment compared with hemp seed. Each seed or cutting grows into a cannabis seed factory with almost free and practically unlimited inputs of sun, water and soil.
As CO2 emissions continue to increase, forests of cannabis hemp around the world could literally fix the problem by transforming those increased emissions into beautiful, breathable oxygen. Imagine forests of cannabis hemp overnight, even in the most polluted and crowded of cities. Cannabis Hemp would be available to all who need it, regardless of economic affluence, and our world would be a much better place for it.
