I would like to know, why GMO corn is still being grown.? It does cause bees to be confused and not find their way back to the hive. This happens when water run off from the corn and bees drink the water.
Crop pathogens and pests reduce the yield and quality of agricultural production. They cause substantial economic losses and reduce food security at household, national and global levels. Quantitative, standardized information on crop losses is difficult to compile and compare across crops, agroecosystems and regions. Here, we report on an expert-based assessment of crop health, and provide numerical estimates of yield losses on an individual pathogen and pest basis for five major crops globally and in food security hotspots. Our results document losses associated with 137 pathoge [...]
The global burden of pathogens and pests on major food crops
In 2012, a controversial study on the long-term toxicity of a Roundup herbicide and the glyphosate-tolerant genetically modified (GM) maize NK603 was published. The EC-funded G-TwYST research consortium tested the potential subchronic and chronic toxicity as well as the carcinogenicity of the glyphosate-resistant genetically modified maize NK603 by performing two 90-day feeding trials, one with GM maize inclusion rates of 11 and 33% and one with inclusion rates of up to 50%, as well as a 2-year feeding trial with inclusion rates of 11 and 33% in male and female Wistar Han RC [...]
Lack of adverse effects in subchronic and chronic toxicity/carcinogenicity studies on the glyphosate-resistant genetically modified maize NK603 in Wistar Han RCC rats
Insecticidal Bt crops were grown on more than 100 million hectares in 2017.
Risk assessment considers exposure and toxicity of natural enemies to Bt proteins.
Bt proteins appear not to harm natural enemies.
Reduced insecticide use in Bt crops can enhance the conservation of natural enemies.
Bt technology represents a powerful tool for IPM.
Genetically engineered (GE) crops producing insecticidal proteins from Bacillus thuringiensis (Bt) (mainly Cry proteins) have become a major control tactic fo [...]
Genetically engineered crops help support conservation biological control
Using digitized records from museums and herbaria throughout North America, the researchers were able to track the relative abundance of both monarchs and milkweeds for more than a century, from 1900 to 2016. They found that both monarchs and milkweeds increased during the early 20th century and recent declines are actually part of a much longer trend beginning around 1950.
"Herbicide resistant crops are clearly not the only culprit, and likely not even the primary culprit," the paper states. "Not only did monarch and milkweed declines begin decades before GM crops were introduced, but othe [...]
GMOs not main culprit in monarch butterfly decline
