Genetically modified foods are formed from genetically modified organisms to create a specific change in and organism such as plants, animals or bacteria this change can alter the genetic make up of organisms. This change could provide better nutriance, higher sugars, larger produce, better taste, resistance to disease, or even longer lasting products. This change can be established by using genetic engineering of certain DNA, to produce these certain GM foods.
Scientists have been using these methods for generations and have crossed the genetic make up of animals and plants to produce what they desire and what the world needs to survive better. Here in Australia whole GM whole foods such such as wheat, soybeans, maize and tomatoes are not present in Australia however Genetically modified food ingredients are present in Australia for example GM soy flour in bread which had originated in soybeans. In the following essay I will discuss why Genetically Modified Organisms should be allowed to be produced and sold in Australia.
The three most common methodologies used to create GM products include selective breeding, transgenic cloning and genetic engineering of tissue and DNA. Selective breeding is the process of breeding animals or plants for specific genetic traits, the breeding is directed on professional breeding farms or stations. This form of crossbreeding can create hybrids and new species, which can benefit and produce more of a gene that is much needed.
Examples of selective breeding includes the Belgian blue this cow has been formed over generations by only breeding the two cows with the biggest muscles therefore overtime a cow such as the (Belgian blue) has been formed where they carry a super gene where there muscles are supersized. Transgenic cloning is when they inject the genes of any organism into a new egg to create an exact replica of the organism copied, an example of this includes Scamper, an extremely successful barrel racing horse, he was cloned.
The resultant stallion became the first cloned horse to stand at stud in the US. Genetic engineering Is the manipulation of certain genes in plants or animals and placing them into different organisms to result in a specific change to benefit society, or to help medical research for the future. The advantages of Genetically Modified foods include the following – Pest resistance Crop fatalities from insect pests can be astounding, resulting in shocking financial loss for farmers and undernourishment in developing countries.
Farmers normally use many tons of chemical pesticides annually. Consumers do not demand to eat food that has been treated with pesticides because of potential health risks, and run-off of agricultural spoils from extreme use of pesticides and fertilizers, which can poison the water source and cause harm to the environment. However new GM foods such as B. T. corn can protect these plants from the insect pests.
Herbicide tolerance For some crops, it is not cost-effective to eliminate weeds by physical means such as plowing, so farmers will often spray large amounts of diverse herbicides (weed-killer) to terminate weeds, a time-consuming and costly procedure, that involves care so that the herbicide doesn’t damage the crop plant or the environment. Crop plants genetically engineered to be resilient to one very dominant herbicide could help stop environmental harm by reducing the amount of herbicides needed.
Genetically Modified foods can solve hunger in many undeveloped countries as GM foods can increase the yields of crops and therefore more food is produced by farmers. Scientists can learn to grow foods in different conditions for example pineapples can be engineered to grow in frost conditions. This can be useful for places like Africa where it is hard to gather and create food therefore foods that are usually grown in cold climates may be used in hot climates. Some foods can be genetically modified to contain higher amounts of important vitamins and minerals.
Vitamin A deficiencies cause blindness. In Africa, 500,000 go blind each year. If rice can be modified to contain more vitamin A, the amount of people going blind will decrease. Some foods can be GM to contain a greater amount of major vitamins and minerals. Vitamin A deficiency cause blindness. In Africa thousands go blind each year. An example of a solution is creating rice “golden rice” which can contain higher amounts of Vitamin A and therefore the rate of blindness will decrease. Enhanced taste and quality of foods, Increased nutrients
Dis-Advantages Genetically modified foods may carry deadly/ chemical properties which are greatly unnatural. Some genetically modified foods can cause cancer The GM foods may create new allergies to humans Damaging affects on the immune system Overall I believe that GM foods should be allowed in Australia, as it would provide better farming, crop systems as farming in Australia is relied upon heavily. Despite cons of GM foods I believe that if this kind of strategy was accepted and GMs were allowed in Australia then the whole country would benefit.
Examples of the benefits that would occur includes better nutrition in some food sources where they would normally lack, the enhanced taste of some food sources. For example in Australia obesity is a major problem and if they could make vegetables or fruits taste better then more and more people would eat and slowly become healthier. Another advantage of GM foods that would be relevant to Australia includes the pest resistance and herbicide tolerance as this sort of actions would be valuable in Australia’s farming industry.
The selective breeding of some animals would also help Australians as we have a great variety and many numbers of animals living here therefore we would have animals with specific genes that are valuable and some genes that are not and if we just bread the animals with the valuable genes then I believe that Australia’s food sources would be greater along with the crop industry.
