Protection of Environment (about 250 words)The protection of environment is a global issue which can not be tackled with by a single country alone. Ever since the industrial revolution, more and more coal has been burned as a fuel. Hence a lot of smoke was emitted into the atmosphere and the air we breathe in every day is heavily polluted. Some factories deliberately discharge sewage into the rivers or lakes which seriously polluted the water. The leakage of oil tanks has heavily polluted the sea and made the sea environment unsuitable for the sea animals like whales, dolphins, seals to survive. Through breathing in the polluted air and drinking the polluted water many people have got trouble with their health. With a large of amount of carbon dioxide in the atmosphere, there appears the greenhouse effect on the globe. Carbon dioxide is the largest contributor to the greenhouse effect. According to the scientist statistics, the temperature of the earth is getting higher, on the average, by about 0.3 degree centigrade every year. In another 100 year time, our descendents will not be able to survive on the earth anymore. Now it is most urgent for all the countries in the world, with the industrialized countries in particular, to take concerted actions to fight against pollution. It was the industrialized countries that caused the heavy pollution in the last century, so they should take more responsibilities in controlling pollution on a world wide scale. They should transmit the skill and technology and give financial assistance to the developing and under developing countries.

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 less able to understand messages about genetically modified foods and other health-related information.Parrott Distinguished Professor 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 messages,Food policy, in particular, interests me because having enough food to feed people is a really big issue 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.(switch)Farmers have witnessed 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 emissions. 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 professor 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.
