GENETIC ENGINEERING

Introduction

What is Genetic Engineering? Genetic engineering involves artificial transfer of genetic material, or DNA, usually between unrelated species of plants, animals, bacteria, viruses, and humans. It consists of taking genes and segments of DNA from one species, e.g. fish, and putting them into another species, e.g. tomato. If we think about the uses of genetic engineering we will probably ask some questions about its advantages and disadvantages for the environment or humans, like…What kind of economic and social impacts might we expect from these technologies? How many lives can we save with the correct use of Genetic engineering?...

At present, genetic modification are opening doors in the world of biology, but it could be good or bad, depending on the uses we do in the environment or humans. Some advantages are for example the possibility of growing vegetables in desert areas, it could be the solution to finish the problem of hunger as well as the extinction of plants, animals and insects. In the field of medicine some geneticists are trying to develop new genetic cures for illness (for example cancer) and inherited genetic diseases. Moreover organs could be grown and used in transplants to save lives. On the other hand, there are some disadvantages too. Some scientists are combining the genes of different creatures against the laws of natural selection, and in the future could be an important problem.

Conclusion

Genetic engineering poses serious risks to human health and to the environment. It raises serious ethical questions about the right of human beings to alter life on the planet for the benefit and curiosity of a few. But I think that genetic engineering should continue.
