For many years, people have been altering the genomes of plants and animals using traditional breeding techniques. In recent decades, advances in the field of genetic engineering have allowed for precise control over the genetic changes introduced into an organism. As of today we can incorporate new genes from one species into completely unrelated species through genetic engineering, optimizing agricultural performance or facilitating the production of valuable pharmaceutical substances One of the main pieces of evidence to support the use of transgenic organisms is an increase in crop productivity and enhanced food protection. By the year 2050, the world's population is expected to almost double making food security the most important social issue for the next 30 years. Food production has to be doubled or tripled to meet the needs of the growing population, 90% of whom will reside in the developing world. In 1996 and 1997, the cultivation of virus-, insect-, and herbicide-resistant plants accounted for a 5% to 10% increase in yield as well as for savings on herbicides of up to 40% and on insecticides of between $60 and $120 (U.S. dollars) per acre. In a global sense, a more effective strategy to ensure sufficient levels of food production would be to increase productivity in developing countries, especially in areas of subsistence farming, where an increase in food production is urgently needed and where crop yields are significantly lower than those obtained in other areas of the world. Genetically modified food saves farmers a lot of work and costs since farmers will no longer have depend on the use of pesticides, herbicides, and even fertilizers for that these plants have the ability to resist diseases and droughts. By genetically modifying plants, plant wastes will be reduced which would maximize production. Farmers would have the capability of producing more crops with less seeds used within a short period of time, while cutting down costs. Many crops have been enhanced to ensure that they have the capability of growing in different environmental conditions. For instance, plants like strawberries can be genetically modified for them to grow in frosts regions. On the other hand, there are other foods that specifically grow in cold climates only, and now we can make them grow in the hot climates. With this technology, modification has made food available to grow in places that other plants could not grow. Many plants that are thought to provide resistance to natural herbivores produce a number of toxins and anti-nutritional factors. Toxins in genetically modified plants are of concern to any species in which unsafe levels have been found in its lines, varieties or relatives, or if transgenes are derived from such species. In those cases, GM crops developers must determine if toxins are absent/present within a safe range before commercialization. Toxins present in the food supply don't necessarily come from the plants itself, but could come from pathogens growing on the plant. Food allergies occur in <1 to 2% of the population, and most allergy sufferers are allergic to only a few specific proteins in one or two specific foods. Eight foods (peanuts, soybean, tree nuts, milk, eggs, fish, crustaceans, and wheat) account for >90% of food allergies worldwide. Food allergies are of major concern as people with allergies to those foods can exhibit reactions that are sudden, severe, and life threatening. Antibiotic resistance genes are used to identify and trace a trait of interest that has been introduced into plant cells. Use of these markers has raised concerns that new antibiotic resistant strains of bacteria will emerge. The rise of diseases that are resistant to treatment with common antibiotics is a serious medical concern of some opponents of genetic engineering technology. The potential risk of transfer from plants to bacteria is substantially less than the risk of normal transfer between bacteria, or between us and the bacteria that naturally occur within our alimentary tracts. In Canada, GMOs (genetically modified organisms) used as food or feed must be approved before gaining access to the market. The approval process is covered by numerous regulations and is done by Health Canada for foods, Canadian Food Inspection Agency (CFIA) for seeds and livestock feed, and Environment Canada for new substances intended for environmental release. GMOs for food purposes are classified as novel foods, a category of foods including products never used before as food; or foods that have been produced in a new way, such as genetic engineering (GE); or foods altered by traditional methods such as selective breeding. All novel foods are evaluated by Health Canada for possible safety concerns for humans, animals, and the environment. The safety assessment of a GM food takes between 7 to 10 years. The safety evaluation mostly focuses on the differences that are identified between a GM and its conventional counterpart. Most of the conventional food consumed does not require safety assessments; they are assumed safe due to a long history of safe use. GM foods go through much more safety testing than non-GM foods. As of April 2008, 104 novel foods and processes have been approved by Health Canada, and 71 novel feeds were approved by the CFIA. Although there is a lot of evidence in support of genetically modified crops, I feel that it is debatable for a lot of people are scared to try new technology. This is what i have so far
