Genetically Modified Organisms- a Step Ahead or a Step in the Wrong Direction?

genetically special organisms- a step forwards or a step in the upon direction? Paulina Langowska Genetically modified organisms, also known as GMO, are such organisms whose genetic genuine has been artificially sortd using genetic engineering. Genetic engineering, to gift it simply, is altering the DNA technology, using DNA molecules from various organisms and using this molecules to cre consume a brand peeled set of genes. Then the set of genes is added to an organisms genome. Below is shown an ex miscellany of genes in lemon yellow, which is supposed to protect it from various insects.Genetic engineering lav also change the color of the plant, make it resistant to difficult tolerate conditions, insects and viruses. The beginnings of genetic engineering take us back to the year 1973, when the commencement exercise recombinant bacteria- a bacteria that has been genetically modified- was created. It was Escherichia coli, which from that chief on became a popular scienc e laboratory rat used in genetic engineering. This creation led to discussions whether genetic modifications are safe and needed. The first conference when potential health risks were discussed took place in 1975.In late 1980s in the States and Canada began an experimental usage of genetic engineered plants in a littler scale. In 1990s, after the approval for a bigger scale, genetic engineering was to a greater extent widely spread across the countries. From that point on, the interest in genetically modified organisms grew year by year. However, eve though genetically modified organisms have gained population, the benefits of it and its harmlessness is disputable. Researches on lab pets show many harmful consequences.Some scientists decided to attempt and feed rats with genetic engineered potatoes. It was supposed to make them promote their own inwrought insecticide. But the results werent exactly as they were expected. Rats cells developed in a proliferative look and potenti ally cancerous cells. Also, the development of their brain and liver-colored was inhibited and they suffered from an immune carcass damage. Also, early(a) research was done in Russian Academy of Sciences. This time, effeminate rats were fed genetically modified soy onwards and during pregnancy and also hile feeding their offspring. This time, the results included * About 55% of offspring died during 3 weeks after the make (compared to 9% of mortality among those fed with non-genetically modified soy) * exit was significantly smaller compared to other as easy as their organs (heart, liver, kidneys, etc. ) * Both mothers and their children were real aggressive and anxious * When male and female (both manakin genetically modified soy fed mother) were paired, they were unable to conceive children.Although the results of this experiments are to be taken with a grain of salt, they are tacit alarming and move callable to the wide discrepancies between the GM soy fed rats and t he control ones. The health damages effect in rats fed with genetically modified potatoes is fair(a) as much worrying. The resolve rats are used for such experiments is that their morphology and biochemical structures are very(prenominal) similar to the human ones. That is why those experiments, as well as similar ones, provoke an essential drumhead- is genetically modified viands harmful to people.The answer to this question is very disputable. Some scientists claim that genetically modified foods are all told safe and otherwise they wouldnt be approved. But there are many articles about possible harmful effects of genetically modified foods and they cant be ignored. The main concern is allergies. Main aim of nourishting a new set of gene to an organisms genome is to create a new protein and every protein is potentially triggering to allergic reactions. The problem with GM foods is that its protein are completely new and we cant be received about its effect.Truth be told , people (mainly in USA, where genetic engineered food is the most common) often consume GM products without being aware of it- if you live in the USA and ate cheddar cheese in the past few years it is to a greater extent(prenominal) than likely that you ate a genetically manipulated food, since genetic engineering is presently the most successful in cheddar cheese. Some say that genetically modified products they un ordainingly consumed are to stand accused for their new allergies. Other concerns enquire immunity system damage and stunted organ growth, however they are loosely seen in lab pets and are yet to be proved to occur.Another reason why genetic engineering receives so many criticism from the ethical point of view. Because if we can change genes in cheese or potatoes, whats fish filet us from changing genes in people? Scientists and psychologists are afraid that genetic engineering will fail so developed that designing unborn children will happen on a daily basis. Par ents will choose gender, height, hair color etc. From this point theres not much to go to create an artificial world, ruled by genetic engineering, looking like taken out of Huxleys book.Futhermore, genetically modified organisms have a great impact on our environment. One of the problems is gene flow. Gene flow is a natural occurring phenomenon that results in get one organisms DNA and transporting it to other one, be it from the same species or not. Some people are afraid that the engineered genes may spread and grind out other, not modificated, plants. Yet other drawback is that they can be harmful to other organisms. Genetic engineering in plants such as crop is mostly focused on creating a defensive system once against insects.But often, the newly created insecticide can be harmful to other, non-target organisms. Some sources agree that the existence of genetically engineered edible give most commonly found in corn had a negavite impact on population of monarch butterfli es living near the field, because they fed with plants dusted by the pollen from the corn maize. Both these phenomenas can led to destroying natural biodiversity. So this leads us to a question if genetic engineering has so much disadvantages, why is it still done and money is spent for researches?The truth is that horizontal if it has many drawbacks, it still have many advantages that for some people are worth all the effort. shun poster about GM foods One of them is that it is tell to service of process us create food that is much more nutritious. It can be done by inserting a specific genes that are supposed to formulate vitamins etc. to various crops. A well known case is inserting the gene do the vitamin A levels in rice much higher. Rice feeds currently more than 50% of the world population, but is not high in vitamins and other nutrients.Modifying it in such a way that It contains more vitamin A could help slim deficiency resulting in blindness. If it was to be done su ccessfully with other food products it would probably really help with flake the malnutrition in third world or developing countries. Moreover, genetic engineering can decrease crop failure. Crop failure is a very big issue and it is said to increase due to climate changes. Because of them, price of food gets higher, some countries need to ban all the export of some products (for utilization Russia banning wheat export in 2010) and ometimes it even gets so bad country really suffers from famine, especially when we consider developing countries. Thats why GMOs are so tempting to scientist. They hold potential for making plants more resistant to various insects and plant diseases. Some corn produce very much food but dont defend themselves again insects while other that are able to repel insects cannot produce this much food. Therefore, scientists hope that they can unite these to and create a corn and then other plants that repel insects while producing big amounts of food.This al so results in using o plants much less chemicals in order to reduce insect and disease damage. These chemicals ill hurt our environment. Thanks to adoption of genetically engineered of corn, cotton and soybeans during years 1997 and 1998 farmers used 8. 2 million less pounds of chemicals. Furthermore, genetically modified organisms are also more resistant to getting overrun or choked up by weeds and other plants fighting for the same nutrients. This results in weeds dying out, going away room for crop.This and making plants more resistant to insects and diseases makes GMO very profitable. According to some economists, in 2007 farmers made surplus $10 billion due to introducing gnetic engineered plants. Yet another advantage of genetic engineering is the fact that it can help us produce new, far more effective vaccines and medicines. Also they can create another form of them- edible vaccines. The idea is to put medication into some plants genes and distribute it virtually the wor ld so that people eat it and get what they need.Scientists have already developed a transgenic potato, that prevented rats from getting rotavirus and E. coli. Hopefully, this idea will get developed and take in life, because this could help serious health problems, for suit in countries of the third world. To conclude, genetic engineering is a very controversial subject and it surely require more research. But it holds great potential for touch on many issues, many of them considering developing countries and people dying of starvation. Probably, as more and more investigation is done, health problems are going to be solved.Bibliography Pictures (in order of appearance) 1. http//www. ces. ncsu. edu/resources/crops/ag546-1/helixes3. jpg look 8. 05. 2011 author unknown 2.
