Genetically Modified Food Essay
Genetically modified foods have shaped and formed many debates on whether foods should or should not be genetically modified and there are many reasons as to why. Genetically modified foods are foods that are compromised of organisms which have been genetically altered. There are several reasons being affirmative on genetically modified foods, such as supporting the occurrence of diseases and they are said to be faster in growth. However there is a negative side on genetically modified foods. Genetically modified foods could cause harmful side effects to the body and the (BT) added to GM foods is unsafe for the body. The topic of genetically modified foods is an extremely controversial topic and brings many opinions to whether it is right or wrong. Genetic modification of foods is done by changing the genes of a cell. Genes are a progression of bases which code for a sequence of amino acids. Amino acids make up proteins which we need for our body to function. The DNA is made of the four bases; Adenine, Thymine, Cytosine and Guanine. Genes are then added or taken from the DNA which changes the colour, size, shape, nutritional value or the way in which the plant or animal grows. With support from scientists farmers have been genetically modifying their crops for quite a long period of time. Foods that are genetically modified unusually include and consist of canola, soy beans, rice corn and various others. Genetically modified foods are banned in numerous countries such as France and other European countries. On the other hand, genetically modified foods are a substantial part of society in Australia; it is in most supermarkets and is something we eat daily. GM foods have no labels on products that declare to consumers whether the products have been genetically modified or not. This causes and is due to consumers having to decide and become unsure about the product selling, whether what they are buying is genetically modified or genuinely natural. A reason affirmative why foods should be genetically modified; is that one of the major benefits is they facilitate in controlling the occurrence of certain diseases. There are several foods that cause allergies to certain people when products consumed. By modifying the DNA system of these foods, the properties causing these allergies are eliminated successfully. It has been said that experts and scientists are working on developing foods that have the ability to cure diseases by genetically modifying foods. Gene technology is similar to traditional breeding, and there is a chance of increasing or decreasing levels of naturally occurring proteins, toxins or further unsafe compounds in foods. Foods that are usually developed traditionally are not normally tested for these types of substances; however they often happen naturally and can be affected by breeding. The use of genes from identified allergenic sources in alteration experiments is not prohibited. If a transformed product is found to stand as an increased risk of allergenicity and it should be put to an end. Scientists have the same opinion that normal tests for allergies in foods should be continuously evaluated and improved, plus caution and concern should be practiced when evaluating all new foods, including those resulting from certain crops. Though developers and manufacturers of genetically modified foods make sure that there are mixtures of advantages of consuming foods in society, a lot of the population is entirely against them. A disadvantage of genetically modified foods is that the biggest threat caused is they can have dangerous and harmful side effects on the human body. It is believed by experts that consumption of these genetically modified foods can reason for the development of diseases which are protected by antibiotics. Additionally, people who consume such foods have increased chances of developing cancer. Besides, genetically modified foods are new inventions, not a lot is well-known about their long-term effects on human beings aswell. A reason for harmful side effects may be because of Gene transfer. Gene transfer from genetically modified foods to cells of the body or to bacteria would cause strong concern if the transferred genetic material has harmful effects. This would be mainly important if antibiotic resistance genes, used in creating genetically modified organisms were to be transferred. Though the likelihood of gene transfer is low, the use of technology without antibiotic resistance genes has been encouraged. There are many other things that could cause harmful side effects, however, as the health effects are unknown, many people prefer to stay away from genetically modified foods. It is also been said that genetically modified foods grow faster than the foods that are grown in the normal manner. Due to this, efficiency increases this then provides the population with more food. Several people believe that there is not enough food in the world to feed everybody; this is why genetically modified foods could potentially cure and solve hunger around the world. As genetically modified foods enlarge the size of crops, additional food is produced by farmers. Therefore, this prevents crops going to waste. If pests are unable to eat the crops, this results in nothing going to waste. As a result, farmers make extra money. It is also said that genetically modified foods are extremely fortunate and lucky in places which experience numerous droughts, or where the soil is lacking ability for crop growing. This is why it is difficult to grow normal crops. Now, we can begin to grow foods in different circumstances. For example, strawberries can be able to be genetically modified to grow in frosts. Other foods that grow in cold climates could be engineered and modified to grow in hot climates, such as Africa where much of the continent lacks to provide food. A disadvantage of genetically modified foods is by adding bacterium (BT) to the cells keep insects under control may not be safe for humans. To genetically modify the crops, the type of bacterium that is added is unhealthy for some people to choose to wear cotton clothing or have jobs associated with cotton. Workers in India that had jobs which were involved in handling genetically modifies cotton caused numerous allergies to the workers. They developed itchy and reddened eyes, rashes on skin, blocked noses, nasal discharge and extreme sneezing. This resulted in some workers ending up having to go to hospital or consume antihistamines daily. This was shown by Stephen Lendman, Global Research showing types of harm from GMO. There are many other examples involved with this type of harm from the (BT) cotton plant, additional cases included sheep which grazed on the (BT) cotton. As well, after a period of time they then became sick and then resulted in death. Adding a bacterium to maintain insects away may possibly not be worth impairment of animals and people. Given the evidence shown, genetically modified foods have equally its advantages and disadvantages. If food is continuously genetically modified, it will still have benefits to us; however it comes along with a lot of risks. The decision whether foods should be genetically modified or not is an extremely debatable topic. Aswell, genetically modified foods are a huge part of society and are in our everyday life. Having foods genetically modified has become so common, that most likely it will on no account be stopped, although some people choose to stay away from these types of products as it keeps them healthy and well. http://www. geneticallymodifiedfoods. co. uk/fact-sheet-pros-vs-cons. html http://www. geneticallymodifiedfood. com/ http://www. foodstandards. gov. au/consumerinformation/gmfoods/ http://www. ornl. gov/sci/techresources/.
