Imagine growing the most powerful crop in the world to benefit mankind! You are probably wondering, how can this be possible? This method is called GM crops or named genetically modified crops. Few general questions are asked about this new biotechnology. First question is, “what is this” or “what is this method?” Second, question may be, “is product beneficial or desirable?” Thirdly, are there any risks involved in this new biotechnology? These three questions will be discussed in this paper.


The first thing might be some general history and background of GM crops. It was first introduced in 16 for commercial production. Today, these crops are planted on more than 10 million acres worldwide (Pew initiative on food and biotechnology. 00). The largest producers of GM crops are in the United States, while Canada came in close second. The United States has two thirds of GM crops (p. ). In 1, it had grown to 50 million acres worldwide. This rapid increase grew concerns in Europe over the health and environmental impacts. With all this in mind, businesses had to change labeling, planting, marketing, and other things to sell and inform the consumers (Peterson, G. & Cunningham, S. 000). The risks and concerns are going to be more informative later in the paper. This new biotechnology is here to stay no matter what little risk and concerns that people may have presently.


In addition, “what are the GM crops?” The scientists will select desired gene or genes from donor organisms and inject these traits into recipient organisms without the long process of cross-pollination trails that emerge with the same result (English Nature. 000). The genetically modified organisms are the biological characteristics, through means other than conventional breeding programs or natural selection (p.). These advances in biotechnology have allowed scientist to accomplish genetic alterations of crop plants in 10 to 15 years that would have taken millions of years if left to chance and hundreds of years if left for traditional breeding methods (Waidyanatha, U.P. 001). Three basic steps are involved in genetic modification of a plant. First of all, is the isolation of a gene or genes from a donor organism. The second step is to transfer of the genes to a recipient plant. The third and final step is the expression of the genes resulting in the appearance of a new trait in the recipient (Barrett, K. 17).


Now that we are a little more familiar about GM crops and there history, the next question would be, are the GM crops beneficial? Soybean, maize, cotton, and canola are the four major GM crops (Fresco, L. 001). The benefit of this new biotechnology will help farmland, particularly wildlife if their use results in less intensive farming practices. Another way GM crops benefit to agriculture is, GM trees can be beneficial to forestry (p. ). If this is not enough, in Tucson, Arizona researchers did a study of GM crops and weeds. They fed “fend off pests” that was put on plants and weeds and it made it stronger. The weed they chose was a sunflower that was tested. The gene did not harm the physical fitness or the reproduction of it. They grew more plentiful and wildly spread out in land while deprived of water and nutrients, compared to the ones that wasn’t injected with “fend of pests.” They were dying and the others were damaged greatly by the insects. “This could be a start to crossbreed with crops and weeds,” said the researchers (Snow, A. 00).
