Do You Agree or Disagree
Genetically Modified Food (GMF) has the potential to solve many of the worldââ¬â¢s hunger and malnutrition problems, and to help protect and preserve the environment by increasing yield and reducing reliance upon chemical pesticides and herbicides. So I think that GMF should be a good solution for the worldââ¬â¢s increasing population. The world population has reached 6 billion people and is predicted to double in the next 50 years. The more increasing of population will lead to the more requirement of food and also the lack of suitable land for agriculture.Therefore, when the population is growing dramatically like this, many people would die and many children are malnourished because of food shortage. Ensuring an adequate food supply for this booming pollution is going to be a major challenge in the near future. One of the most solution for this problem is the GMF because of it potential in solving worldââ¬â¢s hunger and malnutrition. With many kind of products, including potatoes, corn, soybeans, beets, and rice, etc, GMF can replace apart of normal foods.Moreover, crop losses from insect pests can be staggering, resulting in devastating financial loss for farmers and starvation in developing countries. Farmers typically use many tons of chemical pesticides annually. Consumers do not wish to eat food that has been treated with pesticides because of potential health hazards, and run-off of agricultural wastes from an excessive use of pesticides and fertilizers can poison the water supply and cause harm to the environment. Growing GMF can help eliminate the application of chemical pesticides and reduce the cost of bringing a crop to market.Besides that, for some crops, it is not cost-effective to remove weeds by physical means such as tilling, so farmers will often spray large quantities of different herbicides to destroy weeds, a time-consuming and expensive process, that requires care so that the herbicide doesn't harm the crop plant or the environm ent. Crop plants genetically-engineered to be resistant to one very powerful herbicide could help prevent environmental damage by reducing the amount of herbicides needed.The last but not least is that GMF can increase yield by using many genetically modified technology. So we can say that the environment can be protected and preserved by increasing yield and reducing reliance upon chemical pesticides and herbicides. I think that genetic engineering is the inevitable wave of the future, and we cannot afford to ignore a technology that has such enormous potential benefits, especially in solving the worldââ¬â¢s increasing population. Do You Agree or Disagree? Some people claim that universities should give the same sum of money to their students' sports activities as to their university libraries. They point out that universities should attract more students to exercise, because a healthy body can make a student bear the heavy studies. On the other hand, most people, like me, strongly disagree with it. In the following paragraphs, I will explain some main reasons. In the first place, an obvious advantage to spend more money on libraries is that enormous libraries can help us save a huge amount of money, paper resource and the time to seek study materials from a far bookstore.As we all known, the prices of books are more expensive than before, while we have to read more books to catch up with the high-tech era. Moreover, now many students are still too poor to go to school, therefore libraries become the cheapest places to provide useful knowledge for them. Just imagine these poor persons can enjoy a varieties of books in a comfortable env ironment with enough light and a quiet study atmosphere. How happy they are! Secondly, another reason why I disagree is that the chief goal of university education is to teach students working skills.Obviously, libraries provide more useful information to students than sports activities do. For example, more and more libraries are also equipped with computers which can encourage students to surf the Net to widen their horizons. Without the Internet, there will be less chances to make friend with the foreigners and catch the latest worldwide information. On the contrary, sports activities are just limited in a small area and a few of friends in some degree. However, I don not deny that sports activities can provide chances to develop some good characteristics, such as cooperation.But frankly speaking, it is a bit wasteful to spend too much money on sports activities, when we can attain enough free exercises, such as running, which gain the same advantages as well. Furthermore, studen ts are easily obsessed by the activities and overlook their studies. For instant, I once used so much study time to play basketball that I failed to go up to the next grade. Although I earned some awards of basketball matches at that time, I feel very regret. In fact, numerous students have the similar stories because of he attraction of the sports activities. In conclusion, I firmly disagree with the idea that universities should give the same sum of money to their students' sports activities as they give to their university libraries. Nevertheless we are sure that both universities libraries and proper sports activities are valuable. Anyway, to avoid students playing overtime and ignoring their homework should be concerned. Is it wise to spend more money on universities libraries?
