  2. 2. What is gmo?<br />A genetically modified organism (GMO) or genetically engineered organism (GEO) is an organism whose genetic material has been altered using genetic engineering techniques. These techniques, generally known as recombinant DNA technology, use DNA molecules from different sources, which are combined into one molecule to create a new set of genes. This DNA is then transferred into an organism, giving it modified or novel genes. Transgenic organisms, a subset of GMOs, are organisms which have inserted DNA that originated in a different species.<br />
  3. 3. ANTI GENETICALLY MODIFIED ORGANISM<br />INTRODUCTION<br />Definition of Genetically Modified Crops (GMOs)<br />Before I go more in depth about the pros and cons of genetically modified crops, let me first give a definition of what genetically modified crops are.<br /> Genetically modified crops (often abbreviated as GMOs) are simply crops, whose genetical material has been modified.  There are two ways to do this:Traditional selection and breeding (much like breeding animals),Modern, scientific modification of the crops.<br /> In this article, my strengths and weaknesses of genetically modified crops list will deal with the second, the scientific effects and applications.<br />
  4. 4. The Disadvantages Of GMO<br />Harm to other organisms. For example genes and their effect included in a crop may turn out to be poisonous to insects (monarch butterfly poisoned by GMO corns).<br />Cross-pollination with traditional, organic plants. Cross pollination can occur at quite large distances. New genes may also be included in the offspring of the traditional, organic crops miles away. This makes it difficult to distinguish which crop field is organic, and which is not, posing a problem to the proper labeling of non-GMO food products.<br />
  5. 5. Spread of new, more resistant "super weeds<br />Spread of new, more resistant "super pests".<br />Major trading countries that obtain most of the benefit from the production and trade of genetically modified crops. This might cause more geopolitical conflicts.<br />New trade, tariff and quota issues may arise between countries, regions.<br />Critics say GMOs may cause health problems.<br />As the USA is the biggest producer of GMO crops, their exports may rouse more anti-American feeling, due to “Americanization” worldwide.<br />
  6. 6. Possible damages to the environment.<br />Possible greed of GMO manufacturing firms.<br />Unharmonized test-, and safety standards around the world.<br />GMOs are made because it is possible to make them, not because consumers feel their need.<br />Possible creation of new kinds of weapons; genetic food and beverage weapons.<br />Additional costs of labeling whether products are GMOs or not. This might increase costs of foods.<br />Unforeseen risks and dangers due to the complexity of nature.<br />
  7. 7. Widening corporate size gaps between food producing giants and smaller ones. This might cause a consolidation in the market: fewer competitors increase the risk of oligopolies, which might increase food prices. <br />Larger companies might have more political power. They might be able to influence safety and health standards (example: less stringent regulations, standards and requirements).<br />Activists’ increased ability to boycott and influence food market, food retailing, and food prices. <br />
  8. 8. Allergies may become more intense, and also, new allergy types may develop.<br />Discrepancies in information flow. GMO producers stress the benefits, but are reluctant to talk about risks and dangers.<br />planting GMO crops may be devastating our food supply. Plants that are resistant to herbicides may cross with weeds, creating super-weeds which could choke out other food crops. Organic, natural food crops are easily contaminated with GMO crops by wind or insect cross-pollination, and these natural crops, especially corn and soy, are almost entirely contaminated by GMO traits now. This is ruining our natural food supply. <br />
  9. 9. MY CONCLUSION<br />According to my research I choose anti GMO because its have many harmful effect in all organisms. And its possible that our environment will be damages by using it. And it will cause health problem.<br />GMOs produce massive changes in the natural functioning of a plant's DNA. Native genes can be mutated, deleted, or permanently turned on or off. The inserted gene can become truncated, fragmented, mixed with other genes, inverted or multiplied, and the GM protein it produces may have unintended characteristics that may be very harmful.<br />
  10. 10. GMO's also pose other health risks. When a transgene functions in a new cell, it may produce different proteins than the ones intended. They may be harmful, but there's no way to know without scientific testing. Bt-toxin is the pesticidal protein that is produced by the cells of genetically modified plants.<br />Imagine what might happen if the genetically engineered DNA which produces pesticides were able to insert itself into human cells, and the damage that this could cause. <br />So we will see the harmful effects of GMO so why we don’t avoid to use it? <br />
