In our daily lives we have a substantial need for food. Everyone on planet Earth needs food to survive day after day, so engineers have begun modifying plants and crops to create a better source of nutrition for the population. Scientists are pushing the boundaries to create bigger harvests and, as a result, healthier people. Imagine what could happen if there were bigger harvests, more succulent fruits and nutritious vegetables. Our imaginations can run wild with the endless possibilities of genetically altering food. However, can we be absolutely certain that what we are doing to our food supply will benefit us in the long run? If a seemingly simple change in a plant's DNA actually harmed millions of people, it would be extremely harmful to our society. Genetically altering foods, such as fruits, vegetables and crops, could cause more harm than good to the people who consume them and have a negative effect on the environment by spreading and destroying other plants. According to the World Health Organization, “WHO,” all currently used genetically modified foods have been evaluated for safety and pose no risk to human health. The WHO also warns that foods need to be assessed on a case-by-case basis. The World Health Organization is confident in the way it phrases its statement. They say “unlikely,” which means it's still possible for something harmful to happen. A biologist named Arpad Pusztai has written 12 books and over 300 articles on genetic modification and is a master in the field. In a test to prove that genetically modified foods were safe for the public, Pusztai gave potatoes with altered DNA to a group of laboratory rats. The results were shocking to Pu... middle of paper... e.g., Rick. "EarthSave - Nutrition intervention programs to achieve health independence."
