Every person emits the equivalent of approximately two tons of carbon dioxide a year from the time food is produced to when the human body excretes it, representing more than 20 percent of total yearly emissions. That is what a study by researchers in Spain says, confirming for the first time that human excrement contributes to water pollution, primarily with nitrogen and phosphorus.
