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)

    instead of the harmful genes.4 The second method is genetic engineering with the use of a gene gun. This fires tiny gold particles coated with DNA that produce useful traits directly into a plant's cells5 Now that we have established a basic background on GM, we will now look at the benefits and risks of GM crops.

  2. GM Crops- Should they be grown?

    Higher agricultural yields will inevitably increase labour productivity, Increase farm income, Reduce costs for producers e.g. from reduced dependency on external inputs such as fertilisers and pesticides, and increase effectiveness of herbicides5.

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

    Furthermore, as we become more skillful with the technology, we will be able to produce plants that deliver more than just the above benefits. For example, plants that will produce plastics, industrial chemicals, and even vaccines to counteract many diseases throughout the world.

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

    They say that the most important point is that GM food has not been proven safe, and people should not risk their health by eating GM foods because the damage can be irreversible. I think that this source from the group of "anti-biotech organic foods activists" is less valid and unreliable.

  1. General Motors Social Responsibility Strategy.

    GM cannot just make a car that could have a half chance of exploding if it is not looked after. The business has to make sure that the car is safe to drive on the road and it is not a potential death trap.

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

    This rice has been called 'Golden Rice'. The people in the third world are also taught how to grow GM foods such as the Golden Rice, and crops that are salt and drought-resistant. It could enable farmers, for example, in Africa to grow crops in areas where it has previously been impossible to do so, making it easier for local agricultural schemes to flourish.

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

    Mutations Mutations that alter gene frequencies in populations occur at a molecular level from incorrect DNA replication in the gametes produced by the individuals. Improper pairing of bases leads to daughter strands containing a different genetic code to their parental genome.

  2. Selective Breeding

    If it grows faster in a period of time we can grow more crops after harvesting the first set thus the crops will be higher in number so higher yield. * The reason plants are grown in horticulture is because they are trying to get more attractive plants as plants
