Letter to the Editor: Genetic Engineering Should genetically engineered food be grown and sold in South Australia?
Recently more and more foods that we buy from the supermarket are involved in the manipulation of deoxyribonucleic acid DNA also known as genetic engineering or gene technology The benefits of GM foods The term genetically modified crops refers to foods that have a gene extracted from a living thing, which has been placed into a different food by a scientist Genetically Modified Foods What are the risks of genetically modified crops?
For the past many years biotechnology has witnessed many developments in various fields such as DNA technology The other research published in New Scientist at Purdue University, the research showed that releasing a transgenic fish to the wild could damage native population even to the point of extinction Chris, Therefore, it is evident that GM foods are harmful to our health.
Second, transgenic crops have destroyed our environment and organic farming industry impossible by contaminating organic foods. Advocates of GMO assert that transgenic crops possessed harmful insect resistance and herbicide resistance helps to reduce the environmental contamination. However, the resistance genes injected to the crops could easily spread to the ecological system.
Consequently, the change has resulted in being caught in a vicious circle due to the birth of super weeds and super insect by spreading the genes to them. Also, the emergence of a mutation by biotechnology has altered the ecology and gives rises to destruction natural restoration.
Also, the EPA evaluates risks to human health, non-target organisms, and the environment by pesticides. Even worse, it is impossible to abolish GM crops like it is impossible to dispose of nuclear waste from a nuclear generator.
Restoration ecology plays an important role in organic farming. GM crops have a disastrous effect on organic farming, especially in light of the most important parts of organic crops is keeping its cleanness and lacking of pollution.
However, seeds of GM plants are carried by wind and contaminate the natural plants. GMO contamination will occur once GM crops are cultivated. Therefore, the co-existence between GMO farming and conventional farming or organic farming is very difficult Keisuke, The result showed that airborne GM pollen can be carried hundreds of kilometers in 24 hours, and the pollen was found 4.
Genetic pollution will destroy organic farming industry which care and love pesticide-free, GMO-free vegetables for citizens. Third, GM crops are being forced on the whole world by biotechnology multi-nationals seeking monopolies for their products. After Green Revolution, agriculture in many countries reorganized their own farming industry to increase productivity and tried to change to be the mechanization of agriculture and depended gradually on the petrochemical industry.
It is a true agricultural output has risen, but agriculture is subjugated to Multi-nationals rule forever. By having a lot of output, consumers and farmers get a profit, but companies such as Monsanto, Novartis and Aventis get a lot of profits.
Genetically modified, by definition, is a term denoting or derived from an organism whose DNA has been altered for the purpose of improvement or correction of defects. Since the development of this process, modified foods have become more common throughout the years, and with their increase in production there has also been great controversy.
The purpose of altering the tomato was for it to be resistant to rotting and decaying as quickly as tomatoes usually do. They were not labeled as being genetically modified and they were between two and five time more expensive than ordinary tomatoes, but consumers still purchased them.
However, due to competition, brought on by a tomato made conventionally and with a longer shelf life, the Flavr Savr tomatoes were not profitable. Genetically modified tomatoes were then made into a tomato puree and sold in Europe in the mids, but a couple years later controversy arose over the concept of genetically modifying food. In , a doctor from Aberdeen, in Scotland, published results from a research study he conducted suggesting that genetically modified potatoes, injected with an insecticide gene from the snowdrop plant, were toxic to rats.
A year later it was announced that beginning in , there were to be trials of genetically modified crops engineered to be resistant to herbicides. The purpose of the trials was to uncover the effects of these crops on farmland wildlife. However, this was criticized to be potentially dangerous to nearby crops, as well as honey that could be affected by cross-pollination. Sure enough, later that year pollen from genetically modified oilseed rape, a plant that is used to produce canola oil, was found at beehives almost three miles away.
Two out of nine samples of honey being sold in supermarkets were contaminated in May At this point in time, nine out of ten people were against the idea of genetically modifying foods. Despite the controversy surrounding genetically modified plants and foods in earlier years, technologies have advanced, and in , Soybeans, corn, cotton, canola, and alfalfa were modified to be herbicide and insect resistant, whereas other crops, like sweet potatoes for instance were modified to be able to survive harsh weather conditions.
Genetically modifying foods changes their genetic makeup in some way. The purpose of doing this is to enhance certain aspects of the food, for example, increasing its resistance to herbicides or its nutritional value. Traditionally, this has been done by way of selectively breeding plants or animals for specific genetic traits, however this method has proven to be potentially inaccurate and very time consuming. Genetic modification on the other hand can physically isolate a particular gene and insert it into another substance, enabling it to then posses that quality.
This is done very quickly and accurately. Plants can be made insect resistant, virus resistant, or more tolerant to herbicides. Bacillus thuringiensis is a bacterium that produces a gene for toxin production that is safe for human production. To achieve insect resistance, the gene is injected into the crops that will then be able to produce this toxin on their own, leading to a decreased need for insecticides.
To achieve virus resistance, crops must be introduced to the gene from that particular disease-causing virus. This results in less susceptibility to the disease and higher crop yields. Similarly, to achieve herbicide tolerance, a gene from a bacterium that will transmit resistance to some herbicides must be injected into the crops, in turn reducing the amount of herbicides used. There are many reasons for producing and selling genetically modified foods over those that are traditionally produced.
Originally, the intent was increased protection of crops. Both consumers and producers who feel that genetically modified foods are advantageous believe that these foods can be cheaper, more durable, and more nutritional. Genetically modifying foods is also a way to ensure that with a world population that is predicted to double in the future, a food shortage will not be encountered.
In addition to increased protection from diseases, pests and herbicides, there are other key reasons for genetic modification.
Many crops are destroyed due to troubling weather conditions. Frost can come at unexpected times causing destruction to sensitive crops. Cold water fish have an antifreeze gene which, when introduced to plants like tobacco and potatoes, can lead to a higher tolerance to cold temperatures. Similarly, plants can also develop the ability to withstand droughts. A very important quality of food is the nutritional value that is possesses.
Malnutrition is quite prevalent, especially in third world countries where people tend to rely on only one crop to fulfill their dietary needs. If however, these crops could be genetically modified to contain the amount of vitamins and nutrients necessary to sustain a healthy diet, it would be a great advantage. The hope in this development is that this rice, funded by the non-profit organization Rockefeller Foundation, can be sent to any countries that request it.
Vaccinations and medicines can be very difficult to produce, and they can also be very costly. Through genetic modification there is hope that the ability to produce foods with edible vaccinations in them will become a possibility.
