The invasion of the mutant crops! Is it possible to grow Genetically modified crops (GMOs) in a way that prevents gene transfer from GMOs to conventional crops? In 1994, the first FDA approved GM (genetically modified) food hit grocery stores in the United States; the Flavr Savr tomato had modified genes that would allow it to stay fresh on the shelves longer (Woolsey). That was the beginning of what has become a prominent farming method in the United States. GMO crops can be designed to resist herbicides like Round Up, so that produce crops can be indiscriminately sprayed and only the weeds are destroyed. Some crops, like GMO cotton, are designed to be toxic to common insect pests. Sometimes the modifications just remove unfavorable traits, or increase harvest yields in undesirable growing locations, allowing us to fill supermarket shelves with produce year-round. There is now a growing concern that GMO crops are causing irreversible changes to our conventional (non-GMO) crops and some wild relatives. The concern is that GMO plants are transferring their genetics, and sometimes, full GMO traits, to conventional crops. Many now fear that under-regulated GMO crops could unintentionally alter a major food source in such a way as to make it incompatible with human consumption. Pharming is the process of inserting genes that code for pharmaceutical drugs into common crops, like carrots (kraemer). If those genes were to get outside of the laboratory setting, and into our conventional carrot crops, carrots could become toxic and inedible. The first vector in which GMO crops can transfer their genes to conventional crops is through cross-pollination, where GMO plant pollen is transferred, via wind or bee pollination, to conventional cro... ... middle of paper ... ...etically Engineered Microorganisms."

In the video, “Genetically Modified Crops: Hope vs. Hype”, reveals that a Cornell study followed-up by Iowa state researchers show that “pollen from GMO corn is killing the larvae of the Monarch butterflies, which is not at all what the corn 's designers intended” (“Genetically Modified Crops: Hope vs. Hype”). GMO seeds are contaminating our environment, which were presumed safe before. Genetically-modified organisms are the unorthodox procedure of moving genes from one species to a completely different and unrelated species. These unnatural transferring of genetics are causing death among insects. Undeniably, nature 's long-lived ways are safer compared to the bio-tech 's short-lived ways. They hold many uncertainties.

GMOs are created by inserting DNA from bacteria, viruses or other plants and animals into a "target species" to create desirable traits. Most food today is modified to be resilient against pesticides and/or herbicides like Roundup. The first and only genetically modified food approved by the FDA for human consumption was the Flavr Savr tomato, which was slipped on grocery store shelves in 1994. Scientists at Calgene Inc. altered...

Food is an essential part of everyday life without it one could not survive. Every day we make choices on what we put in to our bodies. There are countless varieties of food to choose from to meet the diverse tastes of the increasing population. Almost all food requires a label explaining the ingredients and the nutritional value allowing consumers to make informed decisions on what they are consuming. However, many may not be considering where that food is coming from or how it has been produced. Unfortunately, there is more to food than meets the eye. Since 1992, “ the U.S. Food and Drug Administration ruled, based on woefully limited data, that genetically modified foods were ‘substantially equivalent’ to their non-GM counterparts” (Why to Support Labeling). GM food advocates have promised to create more nutritious food that will be able to grow in harsh climate conditions and eventually put an end to world hunger in anticipation of the growing population. There is very little evidence to support these claims and study after study has proven just the opposite. GM crops are not only unsafe to consume, but their growing practices are harmful to the environment, and multinational corporations are putting farmers out of business.

In an article titled “The Threats From Genetically Modified Foods” by Robin Mather, he has said that the use of glyphosate, a herbicide, can “significantly increase the severity of various plant diseases” which is very hazardous to the environment. In the same article “The Threats From Genetically Modified Foods” Robin Mather has stated that genetic transfers cannot occur in nature and are not so precise and predictable as people say they are. In another article called “Biotechnology and Genetic Engineering” from Issues & Controversies, it has been shown that genetic modification can affect many plants. For instance, the article stated that In Oregon, there was genetically modified grass that had affected plants nearby which began to ruin all of the crops near the genetically modified

The term GM foods or GMO (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques (Whitman, 2000). These plants have been modified in the laboratory to offer desired traits such as increased resistance to herbicides or improved nutritional content. Also, genetic engineering techniques have been applied to create plants with the exact desired trait very rapidly and accurately. For example, this is done by the geneticist isolating the gene responsible for drought tolerance and inserts it into another plant. The new genetically-modified plant will now have gained drought tolerance as well.
In this day and age, Genetically Modified Organisms (GMOs) have become a topic of large interest in the media. GMOs are defined as an organism whose genetic structure has been altered by incorporating a gene that will express a desirable trait (Dresbach et al. al. 2013). Often times, these traits that are selected are either beneficial to the consumer or producer. Currently, GMOs are being created at a higher rate than ever before and are being used in the foods that we eat.
...ence of GM crops is that genetic modifications can develop proteins in plants which a consumer could be allergic to. For example, one of the most common allergies is with the peanut. What would happen if peanut proteins interlace into tomato seeds? Then people with peanut allergies would not be able to eat genetically modified tomatoes. There are many reasons to stop the production of GM food. It can produce serious long-term nature accidents, but there is no way to know much about it until is too late (“GM Food” 2).
This report explains genetically modified food (GMOs) and discusses the benefits and risks associated with the consumptions of GMOs. Genetically modified foods (GMOs) are foods that have been genetically altered using engineering techniques. The most common technique used today is called recombinant DNA technology; this technology combines different molecules from different plant species to create a plant with a new set of genes, a hybrid plant. Another recombinant DNA technology being used is recombinant bovine somatotropin (rBST) an artificial growth hormone; this hormone is being fed or injected into cows to improve milk production.

GM crops also benefit the economy and assist in feeding more people. While we struggle with feeding our population, “The population will continue to grow” (Calandrelli 1) For instance, genetic engineering in agriculture can minimize the cost of producing food. Thus, GMO’s in crops can result ...
