Article review from Scientific American. Author discusses genetic crop modification and addressses long term impact on the environment

Kathy, Brown. 2001. Seed of Concern, Scientific American, 284:52-57. In this article the source addresses the growing substantiate upon over the risks of familialally modified crops and the possible environmental effect that these plants whitethorn drop in the future. Presently most genetically modified crops fall into dickens main categories; those which are resistant to insect pests because they construct their own toxins, and those which can post a wide range of weed-killing herbicides in stead of harsh pesticides designed to annunciate specific species. Benefits of genetic modification diverge from crop to crop, but generally, GM plants respond to milder forms of pesticides and often do non need to be sprayed as often as ordinary plants. As a result, the amount of pesticide sack that runs off into close groundwater and streams may be decreased, or at least less potent. The author touches on the three regulation concerns of genetically modified crops which are ; the long-run effects of GM plants on non-tar travel organisms, the possible spread of modifies genes into nearby plants and weeds, and the evolutionary response these plants may trigger in weeds and insects. The author stresses that both the risks and benefits of genetic engineering in agriculture expatriate on vague repayable to lack of long-term entropy on GM plants and their effects on insect-populations, weeds, and other species.

Until they gain much insight, scientists are legal proceeding with anxiety and urge farmers to use pesticides responsibly and to intermix genetically modified plants with timeless ones. Reading this article, I got the impression that our knowledge of genetic engineering is still genuinely limited. habituated that the benefits of GM crops are mixed and that the drawbacks and possible long-term environmental effects remain unknown, I reveal it hard to insure why they are being introduced at all.
