Positive and Negative Impacts Genetically Modified Food Has on the World
The term ‘genetically modified food’, also known as ‘genetically modified organisms’, is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques. The reason these plants are being modified today is to enhance desired traits such as increased resistance to herbicides (pesticides used to kill unwanted plants) or improved nutritional content. In order to create these genetically modified foods, scientists must introduce specific changes to their DNA by using extremely precise genetic engineering techniques. While there are some benefits that genetically modified foods may offer, there are also some risks and negative affects that these foods can cause as well.
Genetically modified foods have been helpful in many aspects of the world. Firstly, they have the ability to help meet the growing demands for food supply as the world population has topped 6 billion people and is predicted to double in the next 50 years or so. Ensuring enough food supply for this booming population is going to be a major struggle in years to come, and genetically modified foods will help do this in a number of ways. For example, crop losses from insect pests can be shocking, resulting in devastating financial loss for farmers and starvation in developing countries. By growing genetically modified foods such as B.T. corn, farmers can help eliminate the production of chemical pesticides that cause potential health hazards, and there will be higher crop yields that many experts argue can help to feed people in these countries. In addition to this, plants can be genetically modified to be resistant to bacterial, fungal or viral infestation. For example, sweet potatoes have been modified to improve viral resistance, and bananas have been modified to resist the Black Sigatoka fungus. Growing genetically modified foods will therefore lead to...
