  • My grandmother used to put lettuce in salt water, so all the bugs and snails would float to the top.

  • Sustainable & local is better. Having eggs from a neighbor farmer, the difference is clear - the yolks are orange (not faded yellow), and the whites are firm, not like a watery film. They taste delicious!! And healthy vegetables raised on trace mineral complete & balanced soils have greater levels of active vitamins - the essential things we need to stay healthy!

  • @shinokiba "corn byproducts, such as pollen and detritus, enter headwater streams and are subject to storage, consumption, and transport to downstream water bodies. Laboratory feeding trials showed that consumption of Bt corn byproducts reduced growth and increased mortality of nontarget stream insects. Stream insects are important prey for aquatic and riparian predators, and widespread planting of Bt crops has unexpected ecosystem-scale consequences." ncbi.nlm.nih.gov/pubmed/179236­72

  • @shinokiba "during a 7-day oral exposure to the various treatments (transgenic, imidacloprid-treated and control), honey bee feeding behaviour was disturbed and bees consumed significantly less CCRI41 cotton pollen than in the control group in which bees were exposed to conventional cotton pollen. It may indicate an antifeedant effect of CCRI41 pollen on honey bees and thus bees may be at risk because of large areas are planted with transgenic Bt cotton" ncbi.nlm.nih.gov/pubmed/207007­62

  • @shinokiba "Our results show that transgenic crops expressing Cry1Ab protein at 5000 ppb may affect food consumption or learning processes and thereby may impact honey bee foraging efficiency." ncbi.nlm.nih.gov/pubmed/182062­34

    "Plant residues of transgenic plants, plowed under at harvest and kept mixed with soil for up to 4 months, affected soil respiration, bacterial communities, and mycorrhizal establishment by indigenous endophytes." ncbi.nlm.nih.gov/pmc/articles/ ­PMC1287690/

  • @shinokiba "Organic farming leads to many improvements to the natural environment""increased water retention in soils, improvements in the water table""reduced soil erosion""better carbon sequestration, and increased agro-biodiversity.""soils are healthier""sustain plant growth better and have a higher nutrient content.""this enables farmers to grow crops for longer periods, with higher yields and in marginal conditions." unctad.org/en/docs/ditcted2007­15_en.pdf

  • @shinokiba "With a few exceptions, studies point to environmental advantages for organic farming practices with respect to a) maintaining or building soil quality, b) lessening ground and surface water contamination, c) reducing greenhouse gas emissions, d) encouraging biodiversity, e) conserving water and energy resources, and, f) recycling waste." nal.usda.gov/afsic/pubs/faq/Bu­yOrganicFoodsD.shtml

  • I care about the environment, that is why I only buy genetically altered food.

  • @217Parsons @zzzldividedbyzerozz Farm Systems Trial at Rodale Institute. Comparison of soil characteristics during the 15 year period found that soil fertility was enhanced in the organic systems while it decreased considerably in the conventional system. "Our trial shows that improving the quality of the soil through organic practices can mean the difference between a harvest or hardship in times of drought" Jeff Moyer farm manager at Rodale Institute.

  • Farming systems Trial at Rodale Institute. In 1999 during one of the worst droughts on record, yields of organic soybeans were 30 bushels/acre compared to only 16 bushels/acre from conventionally grown soybeans(Rodale institute 1999)

  • @217Parsons @zzzldividedbyzerozz Farming Systems Trial at Rodale Institute. Compares soybean and maize production under a conventional and two organic management farming systems. Corn yields are comparable in all 3 cropping systems(less than 1% difference)(Drinkwater,1998)
