The large impact that agriculture and food production have on resource use and environmental sustainability has been well-established. But, we still face major food security concerns worldwide. Direct emissions from agriculture represent 10–12% of overall global GHG emissions. The figure rises to 17–32% when we account for the impact of agricultural fertilizer, chemical production, fuel use, and land-use change. Many consider transportation and housing as the largest contributors to household carbon footprints. Yet several researchers argue that dietary changes are among the most economically effective changes that each of us can make to curb our CO2 emissions.
