Facts for Ag Fact Friday

Today is Ag Fact Friday, so here are 10 facts about modern sustainable agricultrue.

Dairy & Livestock Production

#1 The carbon footprint for a gallon of milk produced in 2007 was only 37 percent of that produced in 1944. For every 1 million cows, the reduction in global warming potential from rBST supplemented cows is equivalent to removing 400K cars from the roadways or planting 300 million trees.

#2 Transportation accounts for at least 26% of total anthropogenic GHG emissions compared to roughly 5.8% for all of agriculture & less than 3% associated with livestock production in the U.S.

#3 The use of grain and pharmaceutical technology in beef production has resulted in a nearly 40 percent reduction in greenhouse gases (GHGs) per pound of beef compared to grass feeding.

#4 Bans on feed grade sub- therapeutic antibiotics in European countries lead to increased reliance on therapeutic antibiotics important to human health.

Crop Production

#5 Biotechnology improves insect biodiversity, crop plant diversity, and has lower levels of carcinogens than conventional and organic corn.

#6 The use of biotech Roundup resistant crops has led to reduced herbicide use and allowed roundup to replace other herbicides that were up to 17 times more toxic.

#7 Total decreases in carbon dioxide as a result of using biotech crops was equivalent to removing 6 million cars from the road in 2007. (that’s a lot more than the # of hybrid cars sold in 2007)

Modern Agriculture in General

#8 Rather than having a negative impact on climate change, intensive agriculture has actually has a mitigating effect on climate change with a reduction of 68 kgC (249 kgCO2e) emissions relative to 1961 technology.

#9 Small farms actually benefit more from subsidy programs than large scale farms, despite the relative shares of total subsidies paid. The impacts of subsidies on food choices have not contributed to the obesity epidemic.

#10 Local food production can actually be more energy intensive than modern efficient supply chains. On average, fuel use per cwt for local food production is about 2.18 gallons vs. .69 and 1.92 for intermediate and traditional supply chains for beef production.
