The herbicide resistant transgenic crops and glyphosate Roundup: ecological chain worries

Word:[Big][Middle][Small] 2015/11/23    Viewed:102    
  The latest analysis, released by the genetically modified freeze and Greenpeace, says that nearly 200 independent peer-reviewed scientific studies show that the widely used herbicide glyphosate is unsafe.
  Glyphosate is the active ingredient in Roundup (RoundUp), made by monsanto. To study the relationship between glyphosate exposure and cancer, birth defects and nervous system disease (including Parkinson's disease). Laboratory tests show that glyphosate can cause cell damage, including human embryonic stem cells. Studies also show that glyphosate can interfere with our hormonal balance.
  The evidence also suggests that glyphosate can have a negative impact on rivers and aquatic organisms, and may destroy soil nutrients, make plants sick, and ultimately may contaminate drinking water.
  Glyphosate is widely used herbicide resistant transgenic crops, through a large number of Roundup to eliminate weeds. It leads to weed like Roundup that based on the herbicide glyphosate resistance is more and more strong prompted farmers to use more and more toxic chemicals, and new varieties of "super weeds" struggle. This "arms race" of the pesticide upgrade, has been to people's health and environment to increase the enormous toxic burden.
  1 executive summary
  Glyphosate as the active ingredient of many herbicides and sold around the world, including well-known roundup. Glyphosate based herbicides are widely used in the control of weeds, because they are non selective, glyphosate can kill all the vegetation.
  Glyphosate has been promoted as a "safe" herbicide. However, a growing body of scientific evidence to question the safety of glyphosate and its most famous types of roundup.   Detailed evidence in this report indicates that the herbicide products produced with glyphosate as the raw material may have adverse effects on human and animal health, so it is urgent to review their safety for human and animal health.
  More and more extensive and intensive use of glyphosate in genetically modified (also known as genetic engineering or GE) crops will have a further risk to the environment and human health. Genetically modified crops specifically designed to glyphosate resistant 'RoundupReady' (RR). These glyphosate resistant varieties allow the farmers to spray the herbicide over the growing crop and kill almost all weeds without affecting the crop.
  In North and South America, the major crops, such as soybeans, corn and cotton, which are genetically modified to glyphosate resistant (GMRR) crops, have dramatically increased the use of glyphosate. The agricultural chemicals giant Monsanto Company sales of glyphosate resistant transgenic (GMRR) crops and their production of glyphosate, roundup. Meng Shandou to farmers to sell products and commitment, still through the simplification and reduce weeds to control costs, reduce labor market and financial savings. With the development of health, biodiversity and environmental problems and weed resistance, the actual situation is often different.
  In view of the obvious problems, new GM glyphosate resistant crops should be banned. In a broad sense, genetically modified herbicide resistant crops have been developed as a model of industrialization. As a result, there is an inherent link between GM and non sustainable agriculture, which destroys the basic natural resources of food production.
2 exposure to glyphosate
  Human, animal and plant can be exposed to glyphosate and Roundup through a variety of ways. Farmers, onlookers and other operators can be exposed in their applications, near the natural habitat through the use of glyphosate from glyphosate to drift in the area of contact. Aerial spray applications in some crops, such as the Americas genetically modified glyphosate resistant (GMRR) soybean. Large scale single species planting greatly increased the chance of accidental exposure to nearby or habitat populations.
Glyphosate and Roundup residues but also through its exposure, often found in food and environment. In 2006, the United Nations Food and regulation committee agreed on the maximum residue limits (maximumresiduelevels, MRLs) of glyphosate and its breakdown products in food, but it seems to be more relevant to the type of agricultural production per crop, rather than the safety threshold of human health.
  In view of the new scientific evidence on the health and environmental impact of glyphosate, it is necessary to re evaluate the maximum residue limits in order to update the safety assessment.
  In the environment, glyphosate can be combined with particulate matter and retained in the soil, but according to the different chemical characteristics of the soil can also penetrate the ground water. Glyphosate can also be directly into the sewer and surface water, and has been detected in these two systems. Glyphosate and its degradation products were found in surface water drainage in Canada, the United States, and Denmark. These findings have an impact on surface water quality and drinking water quality.
  There is evidence that glyphosate can do harm to health and the environment, and its release can seriously affect aquatic life. Glyphosate is widely used as a herbicide in soil, water, and in our food. Therefore, it is very important to assess the safety of glyphosate in plants, humans and animals.
3 glyphosate affects human health problems
Independent scientific research has highlighted the urgent need for a re evaluation of glyphosate and its related products. These studies mainly focus on the relationship between glyphosate exposure and its adverse effects on human and animal health, including long-term or chronic effects:
And in the Argentine Chaco, because in the transgenic soybean and rice crops heavily sprayed with glyphosate, resulting in birth defects; in 2009, Argentina's national birth defects than in 2000
