What People Who Care About The Earth ShouldKnow About How Their Food is Grown
Just a few of the issues……. • GMOs • pesticides • artificial/chemicalfertilizers • manure • animal by-products • animal exploitation • loss of wildspace and habitat
Monsanto to Sell Biotech Sweet Corn for U.S. Consumers • By Jack Kaskey - Aug 4, 2011 11:25 AM PT • Monsanto Co. (MON), the world’s biggest vegetable seed maker, said it will begin selling genetically modified sweet corn in the U.S. this year, the first product it has developed for the consumer market.

Organic Agriculture • The production of crops and animals without the use of synthetic pesticides or fertilizers.
NOSB Principles of Organic Production: • Healthy soils and environment • Enhance biodiversity, ecosystem function • Use renewable resources • Plants, animals, techniques are locally adapted • Manage the farm as a system • Traceability
Conventional organic uses manure and animal parts (bones, blood, feathers, bodies) as fertilizer….. Manure problems: herbicide/antibiotic contamination, nitrate-N leaching into ground water, human pathogens such as E. coli and salmonella…..
“Cattle are the primary reservoir of Escherichia coli. This has serious implications for the land-based disposal of organic wastes such as cattle manure, cattle slurry and abattoir waste.” Potential health risks associated with the persistence of Escherichia coli O157 in agricultural environments 2010 D.L. Jones “This study points out the potential human health risks associated with consumption of fresh vegetables grown in soil amended with antibiotic laden manures. The risks may be higher for people who are allergic to antibiotics and there is also the possibility of enhanced antimicrobial resistance as a result of human consumption of these vegetables. “ Antibiotic Uptake by Plants from Soil Fertilized with Animal Manure 2005 K.

Liquid fish fertilizer sprayed on crops to produce high yields on over-tilled, over-cropped soils.
Pastured, organically raised chickens lay eggs in buses that move from one fresh pasture to another.
Pastured chickens are vulnerable to predators who are eliminated by trapping and shooting
Most grocery stores who sell Organic have Zero-tolerance for insects, so Organic farms spray organic insecticides.
Spraying Organic Insecticides = Loss of lady bugs, spiders, and syrphid flies
Spraying “selective” Organic Insecticides, such as Bt, is better.
“Industry Standards” for quality: “ Barbie Broccoli” skinny stems, big heads.
“Conventional Organic” vegetable production – lots of bare soil to control weeds. Murdered soil food web
Conventional Organic Production: Monocrop Desert lots of tillage to manage water, nutrients, and weeds.
Veganic farming and gardening is a willingness to balance our existence with the natural world. the soil microorganisms we try not to disturb with excessive tillage, the birds, butterflies, and insects we do not poison with insecticides, the weeds that are not killed with herbicides, and the animals who are not killed for food or fertilizer.
Veganic Works With Nature to Mimic Natural Plant Eco-Systems: Reduced tillage – keeping soil covered, Increased plant diversity, Regular addition of plant residues.
