text: The first reason would be to discuss how the rising atmospheric concentration of CO2 a result primarily of the burning of fossil fuels to produce energy is a growing benefit to plant life. This is an appropriate discussion in a dietary context as atmospheric CO2 is a fertilizer that promotes healthier, more productive plants, including crops used directly as food for humans or indirectly as animal feed. It has been estimated that from the atmospheric CO2 enrichment to date, total crop production as increased by 10-15 percent. This is a positive and beneficial outcome and one that most certainly should be included in any discussion of the role of greenhouse gases emissions in diet and nutrition but is inexplicably lacking from such discussion in the DGAC report.
