Genetic engineering could solve the world's food problems.

Extracts from this document...

Introduction

Genetic engineering could solve the world's food problems. Genetically modified foods look to be a great discovery for the future, however, when looking at the science behind it, does it suggest the same thing? Growing genetically modified plants would supposedly increase the number and quality of crops produced. Genetic engineering can also help develop disease resistant plants and plants that grow in areas that have not been cultivated before. This may not be possible if the structure of the DNA of a plant is altered in a way that could be detrimental for the human and animal population. Evidence from experiments conducted shows that rats that were fed GM corn developed abnormalities in their blood and internal organs. These abnormalities were absent from the group of rats that were fed non-GM corn [1]. Rats that were fed on GM potatoes had an increased crypt length of the intestines and an increase in the mucosal thickness of the stomach [2]. ...read more.

Middle

The fact that these crops have had an effect in rats and mice would suggest they would also have effects in humans. This evidence illustrates that genetic engineering in its present form will not solve the world's food problems. Since 1996 when GM soya was first grown there have been no reported problems from the consumption of GM foods. Regulatory authorities are satisfied that all GM foods produced so far are safe. All the GM foods available have been thoroughly tested. Foods may be able to be modified to stop people having allergic reactions, more tests need to be done before foods like these are commercially available [3]. A 13-week study of rats in two groups being fed GM corn and non-GM corn showed no test related changes in evaluation of survival, clinical signs, body weights, body weight changes, food consumption, clinical pathology, organ weights and macroscopic and microscopic pathology [7]. ...read more.

Conclusion

Also, for example, if a growth gene in a tomato was changed with no adverse effects, this doesn't mean there will be no ill effects if the same gene was changed in a potato. Further tests could be done on monkeys as they are more closely related to humans, this could show some effects of GM crops that previous tests have not shown. The evidence above shows that by genetically modifying crops there can be an increase in volume and quality of yield. This shows that genetic engineering can solve the world's food problems. However, this does not mean that there will be no adverse side effects of the genetically modified crops. I think that genetic engineering is good for developed countries, but for developing countries the loss of trade for many crops could be disastrous. However, if the GM crops were freely available it could solve the food problems in developing countries as well. ?? ?? ?? ?? Carly Wilson 12S ...read more.

    Genetically modified crops are also strictly controlled by the law. Such UK laws include: The Genetically Modified Organisms (Contained Use) Regulations 1992 and The Genetically Modified Organisms (Deliberate Release) Regulations 1992. These laws are in addition to the standard For Safety Act which specifies that food 'must be fit for consumption'.
