Genetically Modified Animals Essay

Nowadays a problem of genetically modified food is widespread all over the world. GM foods are genetically modified using biotechnology. More and more GM foods appear on the shelves of our stores and supermarkets nowadays, and make their way into our kitchens. GM foods are designed for greater resistance to viruses and pests, higher nutritional value and longer shelf life. However, their safety, potential risks and ethical concerns are still being debated. So, should genetically modified crops be banned or not?

Proponents of GM foods ensure that these foods are safe for human consumption, but critics argue that their effects have not been studied long enough. First argument for banning GM foods is that it badly affects our health and well-being. Some studies have linked consumptions of GM foods to liver and kidney problems. The antibiotics and hormones given to cows and chickens are found in our bodies and we don’t know yet the extent to which these cause chronic disease. Moreover genetic engineering could introduce allergens into foods, causing allergic reactions in people who eat the foods. Another argument is that GM food does not benefit people, just large corporations that produce and sell them. In the most cases the vegetables are modified to look better and be larger so that these companies can make more money. They do not add to the taste or freshness of nutrition of the food.

On the other hand GM products along with disadvantages have their benefits too. A lot of people believe that genetically modified foods can help to solve the food crisis in future, and so help humanity to survive. Firstly, all of sorts of GM plants are stable against illnesses and mean weather.Also, GM food is cold tolerant. An antifreeze gene has been introduced into plants such as tobacco and potato. With this antifreeze gene, these plants are able to tolerate cold temperatures that normally would kill unmodified seedlings.  Secondly, they ripen fast and keep longer than usual plants. It is easier to transport them and keep fresh for a long time.

In my opinion, genetic engineering should be banned because young generation will have different diseases because of eating unhealthful food. Of course, this is a huge industry nowadays that obviously can’t be stopped, but I believe that there are other ways to save people from hunger.

Genetcally Modifed Animals2of DNA. By 1972 researchers developed a method for cutting and splicing DNA. In 1974 RudolfJaenisch was the first to make a transgenic mouse. He was able to introduce foreign DNA into the early stage of a mouse embryo. This has taken selective breeding to the next level. It is said to be more precise. A genetically modified animal is a animal that has its DNA sequenced altered that does not naturally occur in nature. This can mean adding a new trait or taking a trait out. These traits can enhance growth or be disease resistance. When you change an animals genetic make-up it will be transmitted to the next generation of that animal. While genetically modified animals brings up the ethical issues like the well being of the animal.In the early stages of genetic engineering they where transgenesis. That means transferring the genetic material from one animal to another. Now we no longer have to transfer genetic make-up. We can make a engineered animals via the deletion of genes or the manipulation of the genes the animal already has. With there being many different terms for genetically modified animals. We have adopted the umbrella term "genetically engineered" from the Canadian Council on Animal Care (CCAC). The CCAC define genetically engineered animals as "an animal that has had a change in its nuclear or mitochondrial DNA (addition, deletion, or substitution of some part of the animal's genetic material or insertion of foreign
