Environmental Effects of
Genetically Modified Organisms

Genetically modified organisms have been developed for many reasons. Crops have been developed to be pest resistant and drought tolerant with improved nutrition (For more information on the improved nutrition of GMO, click here). Fish have been developed to reach maturity faster. Medicines and vaccines from genetically engineered plants are being heavily researched (Click here to read about this topic from another amazing website). As with all new developments, there is always speculation as to if the benefits outweigh the costs.

  Transgenic salmon are still confined in labs, and have not yet been approved for the market partially because of the Trojan gene hypothesis. (Read the article here.)

GMOs affect the environment in various ways. In this website we will be discussing the positive effects of GMOs, such as; ecological conservation and bioremediation. We will also have information on the negative effects of GMOs on the environment, such as; toxicity to the environment, gene transfer, and insecticide resistance.

Golden rice has been modified to contain more of the vitamin beta-carotene, to act as a supplement.
