If I remember correctly from my biology classes, whenever animals exhale, they are exhaling carbon dioxide. With over six billion humans, and how many billions of other animals on the planet, how much of the carbon dioxide being spewed into the environment is the result of simple breathing? Do we all need to start holding our breaths?
And along the same lines, I also remember hearing that plants require carbon dioxide to live. So if we do hold our breaths and are able to eliminate other sources of carbon dioxide emissions, how are the plants going to live?
