Today, children are taught that carbon dioxide is a poison. No — it is odorless, colorless, and non-toxic. We drink it in fizzy drinks and lager, and it puts the rise in our daily bread. Most importantly, it is one of the most important components of all life — photosynthesis converts CO2 into oxygen and carbon, life’s main building blocks. As long as plants have sufficient water and nutrients, their growth is enhanced by rising concentrations of carbon dioxide. CO2 is the free airborne fertilizer of the world.
Many experiments prove this fact of a carbon-rich atmosphere, experiments corroborated by millions of farmers across the world who cash in on the use of enhanced carbon dioxide in their greenhouses. Many even burn fossil fuel to boost production. Carbon dioxide plays a vital part in providing the 18 billion daily meals that do their best to feed the growing number of people across the world. The once-starving people of parts of the Sahel and Sahara deserts have returned to farm their lands, thanks to the shade of trees that now grow on some 300,000 square kilometers of their tribal lands, thanks in great part to rising levels of carbon dioxide.
