Arguments for and against GM crops.

Extracts from this document...


´╗┐Ketan Singh GM crops 1. What is a GM crop? GM crops are genetically modified crops that have been genetically enhanced using modern biotechnology to carry one or more beneficial new traits. 1. What is the difference between GM and conventional plant breeding? Conventional plant breeding involves changing the genes of a plant so that a new and better variety is developed. New varieties of plants are bred to suit different climate conditions, improve taste or nutritional value, cope with disease or pests better, or to use water or nutrients more efficiently for example. Breeding using genetic modification (GM) also involves changing the genes of a plant so that a new and better variety is developed. It is done for the same reasons as conventional breeding. The key difference is that instead of randomly mixing genes, which occurs as a result of a sexual cross, a specific gene, which is associated with a desirable trait, is selected and inserted directly into the new plant variety. ...read more.


-Could benefit human health and this is related to health. This is because GM crops eradicate disease so it therefore does not create human health issues as they can repel viruses and fungi and are less toxic. -Could reduce pesticide and herbicide use and this is environmental, health, social/ economic/ political effects. This is because they have improved traits and therefore are resistant to viruses and fungi. They also increase the yield of crops and thus, do not require herbicides and so reduce costs. -Could help preserve natural habitats is environmental. This is because the efficiency gains from GM crops will place less pressure on wild or natural habitats and thereby help preserves biodiversity. In addition, Eutrophication is prevented as less fertiliser is used. The people against GM claim that: -There will not be enough to feed the world which is health and social/economic/political effects. This is because GM seeds are much more expensive than conventional seeds and therefore means the poor cannot afford them, and thus they cannot be fed. ...read more.


-It mainly benefits big biotech companies which are social/economical/ political effects. This is because they claim most of the profit for the GM seeds and these companies are also concentrating their efforts in high-volume crops, such as soybeans, corn, and cotton, and not in crops that might help feed the billions of people who live in poor countries. -It raises ethical conflicts over the control of food production which is social/ economical/ political effects. Examples of these are; 1. The possible monopolisation of the world food market by large multinational companies that control the distribution of GM seeds. 2. Using genes from animals in plant foods may pose ethical, philosophical or religious problems. For example, eating traces of genetic material from pork could be a problem for certain religious or cultural groups. 3. Animal welfare could be adversely affected. For example, cows given more potent GM growth hormones could suffer from health problems related to growth or metabolism. 4. New GM organisms could be patented so that 'life' itself could become commercial property through patenting. ...read more.

    Evaluating the risks and benefits of GM crops.

    4 star(s)

    Monsanto produces more than 90% of crops worldwide. Another four companies, Syngenta, Bayer Cropscience, Dow and Du Pont produce the rest. 9Not only are farmers dependent on the fact that there will be these modified seeds for them to purchase every year but like the roundupTM brand by Monsanto, farmers

  2. Food Policy at a Crossroads, A World of Plenty or a World of Famine ...

    By using this method of production, farmers are not only changing the genetics of their crops, but the desired traits that have been engineered into the plant are passed on to the wild weeds or to other offending species. Thus creating super weeds or super pests with increased resistance and requiring higher usage of chemicals.

  1. What are GM foods? - Assessing the risks and benefits

    Strawberries that retain their natural sweetness... ...The list is quite really endless. More than 2 billion people have eaten foods made from genetically modified plants over the last 5 years - and not one person has been shown to become sick. According to 2 American experts on GM, C.S.

  2. What is population genetics and how is it put to practical use?

    it to do so is approximately 4N with large error bars either side. From this model you can see that the size of the population will have an effect on how much genetic drift will affect allele frequencies. This is well illustrated with this graph (Li 1998); This clearly illustrates

  1. General Motors Social Responsibility Strategy.

    The arguments that could be put forward against these responsibilities is that this business already has too much power and that other businesses could be manipulated by GM due to their vast wealth and size. Also, GM believes that there should be certain tax incentives for the company.

  2. GM Crops- Should they be grown?

    bacterial, fungal or viral diseases, improved resistance to herbicides so that crop plants are unaffected by the herbicidal products used to control weeds. Reduced use of pesticides and herbicides has environmental benefits. GM plants can also be developed for removing toxic chemicals from soils and therefore reclaiming previously inhabitable land for crop growth.

  1. The first available GM food was on themarket in 1994, it was a tomato ...

    They say that transgenic DNA from GM foods can survive digestion and can be absorbed by cells which can possible trigger cancer. They say that feeding GM foods to animals which will be eaten by humans will pose a risk to the human eating the animal and the animal itself.

  2. Selective Breeding

    crop yield as when growing the crop we would get more mass for one seed thus the yield would be much higher. By reducing the part we don?t eat in size it will increase the part we do eat in size thus it will give more mass per drop thus more yield.
