Offspring of rats fed GM soy showed a five-fold increase in mortality, lower birth weights, and the inability to reproduce
Male mice fed GM soy had damaged young sperm cells
The embryo offspring of GM soy-fed mice had altered DNA functioning
Many US farmers report sterility or fertility problems among pigs and cows fed GM corn
Investigators in India have documented fertility problems, abortions, premature births, and other serious health issues, including deaths, among buffaloes fed GM cottonseed products
There are countless examples of GM crop failures, as well as GM-associated toxicity being observed in animals fed the plants. For instance, a farmer in Denmark became frustrated because his pigs were sick. The pigs had chronic diarrhea, birth defects, reproductive problems, reduced appetite, bloating, stomach ulcers, weaker and smaller piglets, and reduced litter sizes – and they were being fed GM soybeans.
The farmer looked into the effects of GM foods and their associated herbicides, and stopped feeding his 450 sows GM soy, giving them non-GM fishmeal instead. It only took two days for him to see noticeable results -- for the better.v
GM Crops are Not All They're Cracked up to Be
Virtually all of the claims of benefit of GM crops – increased yields, more food production, controlled pests and weeds, reductions in chemical use in agriculture, drought-tolerant seeds – have not materialized. The Global Citizens' Report on the State of GMOs states: vi
Contrary to the claim of feeding the world, genetic engineering has not increased the long-term yield of a single crop.
Herbicide tolerant (Roundup Ready) crops were supposed to control weeds and Bt crops were intended to control pests. Instead of controlling weeds and pests, GE crops have led to the emergence of super-resistant weeds and super-resistant pests ... Herbicide resistant crops such as Roundup Ready cotton can create the risk of herbicide resistant "superweeds" by transferring the herbicide resistance to weeds.
Despite claims that genetically modified organisms (GMOs) will lower the levels of chemicals (pesticides and herbicides) used, this has not been the case. This is of great concern both because of the negative impacts of these chemicals on ecosystems and humans, and because there is the danger that increased chemical use will cause pests and weeds to develop resistance, requiring even more chemicals in order to manage them.
Monsanto has been claiming that through genetic engineering it can breed crops for drought tolerance and other climate-resilient traits. This is a false promise.
Among the false claims made by Monsanto and the Biotechnology industry is that GE foods are safe. However, there are enough independent studies to show that GE foods can cause severe health damage.
The European Commission has issued a proposal to drop the policy of zero tolerance for unapproved and untested GMOs in food; the proposal suggests setting a threshold below which contaminated imports could enter Europe's food chain
In 2011, the EU decided to allow contamination with up to 0.1 percent of unapproved and untested GMOs in animal feed, which was previously not allowed
France recently asked the European Commission to suspend Monsanto's authorization to plant genetically modified MON 810 corn, but the EU stepped in and blocked the ban
GM opponents are urging the EU to reject the proposals, noting the pressure to drop their zero tolerance policy regarding GM contamination is coming from the U.S. government, the WTO (World Trade Organization) and the biotech industry
