The consequences of genetically modified foods

Uncategorized GE organisms actually become part of the bacteria in our digestive tracts and reproduce continuously inside us. There are no human clinical trials of genetically engineered foods. The only published human feeding experiment revealed that genetic material inserted into GE soy transfers into the DNA of bacteria living inside our intestines and continues to function.

Vietnamese Pocket K No. GM Crops and the Environment The debate over the environmental impact of genetically modified GM crops is growing increasingly complex, intense, and extremely emotional.

It is further complicated as new research is published. Are GM crops safe for the environment?

The consequences of genetically modified foods

Assessing the environmental impact of GM crops is often difficult as many factors are considered. Some scientists focus on the potential risks of GM crops, while others emphasize their potential benefits. Just what are the issues and how can we address them?

What is the current environmental situation? A growing population, global warming, and loss of biodiversity have a tremendous impact on our environment. By yearthere will be 9.

This means that in less than 50 years, world population is expected to increase by 3 billion. Feeding these people will mean massive changes in the production, distribution, and stability of food products.

Unfortunately, cropland and population are not uniformly distributed. For example, China has only 1. The destruction of wilderness and forests, and continued use of coal and oil have led to a steady increase in carbon dioxide levels, resulting in global warming.

It is predicted that the average global temperature will rise by 1. Climate change can radically alter rainfall patterns and therefore require the migration of people and shifts in agricultural practices.

Further, an increasing human population is responsible for wilderness destruction, water quality problems, and diversion of water. The loss of habitat has resulted in many species being displaced.

Thus, to conserve forests, habitats, and biodiversity, it is necessary to ensure that future food requirements come only from cropland currently in use.

What are the environmental benefits of GM crops? One of the significant environmental benefits of GM crops is the dramatic reduction in pesticide use, with the size of the reduction varying between crops and introduced trait. A study assessing the global economic and environmental impacts of biotech crops for the first twenty one years of adoption showed that the technology has reduced pesticide spraying by The technology has also significantly reduced the release of greenhouse gas emissions from agriculture equivalent to removing This corresponds to about a quarter of all the pesticides sprayed in China in the mids.

The adoption of conservation and no-till cultivation practices saved nearly 1 billion tons of soil per year.

GM crops are thoroughly evaluated for environmental effects before entering the marketplace. They are assessed by many stakeholders in accordance with principles developed by environmental experts around the world.

Most countries use similar risk assessment procedures in considering the interactions between a GM crop and its environment. These include information about the role of the introduced gene, and the effect that it brings into the recipient plant.

Also addressed are specific questions about unintentional effects such as: What are the potential risks? Potential of the introduced genes to outcross to weedy relatives as well as the potential to create weedy species Out-crossing is the unintentional breeding of a domestic crop with a related plant.

A major environmental concern associated with GM crops is their potential to create new weeds through out-crossing with wild relatives, or simply by persisting in the wild themselves. The potential for the above to happen is assessed prior to introduction, and is monitored after the crop is planted as well.

A ten-year study initiated in demonstrated that there is no increased risk of invasiveness or persistence in wild habitats for GM crops oilseed rape, potatoes, corn, and sugar beet and traits herbicide tolerance, insect protection tested when compared to their unmodified counterparts.

Direct effects on non-target organisms In Mayit was reported that pollen from Bacillus thuringiensis Bt insect resistant corn had a negative impact on Monarch butterfly larvae.

This report raised concerns and questions about potential risks to Monarchs and perhaps other non-target organisms. Some scientists, however, urged caution over the interpretation of the study because it reflects a different situation than that in the environment.Genetically modified foods, commonly referred to as GMOs, are foods that have been implanted with genetic material from other species of plants or animals.

Controversies

While several major U.S. crops have been genetically modified, the number of genetically modified vegetables is limited. The potential. Genetically modified food controversies are disputes over the use of foods and other goods derived from genetically modified crops instead of conventional crops, and other uses of genetic engineering in food production.

The disputes involve consumers, farmers, biotechnology companies, governmental regulators, non-governmental organizations, and scientists. The safety of genetically modified (GM) foods has been decried by many from the nutritional health community.

One article, entitled, "Genetically Modified Foods Pose Huge Health Risk" claims that thousands of animals fed genetically-modified organisms (GMO) . Genetically engineered foods are just as safe as conventional foods.

In the United States, labeling of genetically engineered foods is not required by the FDA. This is because there has been no significant difference found in nutrition or safety.

“Several animal studies indicate serious health risks associated with genetically modified (GM) food (AAEM ),” including infertility, immune problems, accelerated aging, faulty insulin regulation, and changes in major organs and the gastrointestinal system.

GM corn and Roundup herbicide cause tumors and organ damage. Rats fed Monsanto’s GM corn NK and tiny amounts of Roundup herbicide over a two-year period—the longest ever feeding study involving a GM food—developed severe liver and kidney damage, disturbance to pituitary gland function, and hormonal disruption.
