  23. What is Sustainable Agriculture? • Environmental Groups: “Sustainable agriculture means providing food in ways that do not contaminate the environment or harm humans.” Maureen Hinkle, National Audubon Society • Academia: “There must be a major commitment to a viable farm sector, rural communities, enhanced environmental quality, and overall improvement in quality of life for the farm sector and society as a whole.” G.S. Bird, Michigan St U. • Agricultural Research Firms: “Sustainable agriculture is a high-tech industry that achieves high productivity by drawing on the best in modern agricultural science.” R.L. Thompson, Winrock International • Alternative Agriculture: “A sustainable agriculture is one that can be maintained indefinitely.” Youngberg, H.A. Wallace Inst. Alternative Agriculture • Agricultural Groups: “Sustainable ag is an effort to develop production systems that maintain yields while increasing efficiency of inputs, minimizing the potential for harmful side-effects, and decreasing dependency on nonrenewable resources.” D.R. Swaim, Crop Consultant

  24. Top 10 Reasons to Buy OrganicSource: Organic Times 1992 • Protect future generations—“The average child receives four times more • exposure than an adult to at least 8 widely used cancer-causing pesticides in food.” • Prevent soil erosion--- “...3 billion tons of topsoil are eroded...each year.” • Protect water quality--- “EPA estimates pesticides contaminate the groundwater in 38 states.” • Save energy--- “Farming consumes 12% of the country’s total energy supply.” • Keep chemicals off your plate--- “NAS estimated that pesticides might cause an extra 1.4 million cancer cases.” • Protect farm worker health--- “Farmers have a 6X greater risk than non-farmers of contracting cancer.” • Help small farmers---“Organic farming could be one of the few survival tactics left for family farms.” • Support a true economy---“Conventional food prices do not reflect hidden costs borne by taxpayers, including nearly $74 billion in federal subsidies.” • Promote biodiversity---“Lack of natural diversity of plant life has left the soil lacking in natural minerals and nutrients.” • Taste better flavor---“They taste better!”

  26. Organic Foods May Be Hazardous to Your Health!Is That True? J.G. Mexal Department Curmudgeon

  27. Organic FoodIs That True? Organic Food Production • Is not sustainable! • Is not better for the plant! • Is not better for the producer! • Is not better for the consumer! • Is not better for the environment!

  28. Organic FoodIs That True? Organic Food Production • Is not sustainable! • N deposition (natural fertilization) = 5-10 kg/ha/yr • Sustainable harvest = 250-500 kg/ha/yr (@2%N) • Not enough O.M. in Mesilla Valley • 44,000 milk cows produce over 16,000 t OM/yr • 1 t OM ~ 10 kg N (50% available in Yr-1) • 60,000 ac X 20 t OM/ac = 1,200,000 t OM/yr • Need over 3 million cows in Doña Ana Co.

  29. Organic FoodIs That True? Organic Food Production • Is not sustainable! • Is not better for the plant! • Plants absorb inorganic nutrients • No vitamins, no amino acids, etc • Regardless of source (organic, inorganic) • Actually, a lot of the work is done by beneficial fungi (this is a hint)

  30. Organic FoodIs That True? Organic Food Production • Is not sustainable! • Is not better for the plant! • Is not better for the producer! • Anything profitable, will be ‘WalMartisized’ • Innovators have only a small window of opportunity or niche

  31. Organic FoodIs That True? Organic Food Production • Is not sustainable! • Is not better for the plant! • Is not better for the producer! • Is not better for the consumer! • More expensive (30% to 100% higher cost) • Not safer • No nutritional benefit • How can it be????? • Picked closer to maturity (applies to Farmer’s Market [picked fresh])

  32. Organic FoodIs That True? Organic Food Production • Is not sustainable! • Is not better for the plant! • Is not better for the producer! • Is not better for the consumer! • Is not better for the environment!

  33. Organic FoodIs That True? • What’s wrong with our food? • Too cheap (<11% of our disposable income) • Too readily available • Fast food • Improperly prepared (even the salads) • We have Supersized everything we eat, but Minisized our caloric expenditures. • More people die bicycling than from pesticide residue on foods • Food deaths are caused by handling contamination (fecal)

  34. Activity Smoking Alcohol Driving Handguns Swimming Flying Bicycles Skiing Food additives Pesticides Deaths/year 150,000 100,000 50,000 17,000 3,000 1,300 1,000 18 <1 <1 Here are some real risks!

  35. Pesticide Toxicity • Chemical LD50 (mg/kg) • Dipel 10,000 • Surflan 10,000 • B-Nine 8,400 • Insecticidal soap 5,068 • Pyrethrum <1,500 • Diazinon <735 • Orthene 945 • Sevin 500 • Bordeaux 470 • Temik 0.9
