Its formula is sunlight plus CO2 plus H2O with the green enzyme chlorophyll converts sunlight energy into living high energy sugar bonds, brings the carbon (2nd most abundant element in living species) into our carbon-based life on earth, gives the "environment" its green colour. All of life's carbon, all of life's energy, and as a bonus every molecule of the oxygen we breathe! There is nothing more important to life on earth. And life-essential CO2 has been dangerously and inexorably declining since life's birth to within 30ppm of the beginning of the death of all things. Recycling more CO2 by using fossil fuels has been the greatest contribution to the sustainability of life on earth that human beings have ever done. It delays the death of all things from a lack of CO2. Here's Dr. Patrick Moore, co-founder of Greenpeace. Thank you PragerU... https://www.youtube.com/watch?v=WDWEjSDYfxc
