What's Up With That: What is your carbon footprint? That is the wrong question to ask. A more meaningful question is–How much carbon dioxide does it take to grow the wheat required to produce a loaf of bread? Or–How much carbon dioxide does it take to grow the corn for the chicken feed required to produce a dozen eggs?
Far from being a pollutant, man along with every animal on land, fish in the sea, and bird in the air is totally dependent on atmospheric carbon dioxide for his food supply.
