Hi!Everyone!Today.I will show you something about GM foods.The full name that GM foods is Genetically Modified Foods.This is a hot topic.let’ s start to the present situation of GM foods.According to researchers.People who feel intimidated by math may be le able to understand meages about genetically modified foods and other health-related information.Parrott Distinguished Profeor of Communication Arts and Sciences and Health Policy and Administration.said :“My goal is to help people make informed decisions and to do that, they need to understand and comprehend meages,Food policy, in particular, interests me because having enough food to feed people is a really big iue that we're facing.” Scientists argue that genetically modified foods are safe for consumption and overregulated.the overregulation of GM crops actually hurts the environment, reduces global health and burdens the consumer.(switchFarmers have witneed the advantages of GM crops firsthand through increases in their yields and profit, and decreases in their labor, energy consumption, pesticide use and greenhouse gas emiions.Farmers growing genetically modified rice in field trials in China report higher crop yields, reduced pesticide use and fewer pesticide-related health problems, according to a study by researchers in China and at Rutgers University and the University of California, Davis.Measured on a per hectare(2.471 acres basis, the quantity and cost of pesticides applied to the conventional rice was 8 to 10 times as high as that applied to the insect-resistant genetically modified rice.“What we found was when genes for enhancing the amount of antioxidants and vitamin C in fresh produce were transferred by intragenic methods, consumers are willing to pay 25 percent more than for the plain product(with no enhancements.That is a sizable increase,” said Huffman, distinguished profeor of economics.(switch The basic idea is

that when consumers saw that the intragenic produce had elevated healthful attributes, they were willing to pay more for them.But ,Consumers were not willing to pay more if those enhancements were introduced through transgenic methods.In my opinion, GM food have good prospects.To eliminate the misunderstanding on GM food, scientists should strengthen communication with people.With simple and easy to understand words, tell us that GM food is not so terrible.One day, GM food will benefit mankind.
