    Global warming caused by humans is just a huge lie. Co2 is what our plants live on, then give back oxagen.

    It might help if these so-called experts factored-in the sheer volume of rainforest and other plant life that’s being destroyed needlessly all over the world. Green plant life is the ONE thing that breaks down the molecules, releasing free Oxygen and fixing the Carbon into the structure of the plant. A by-process of photosynthesis is taking nitrogen from the air and fixing it into the earth, to promote a more nutritious growing medium for future plant life. Remove green plant life, and the CO2 levels will rise – simples!
