Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US. 　　　 When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered trees. 　　　 Researchers successfully introduced seeds that were designed to resist the virus. Since then, more and more people have been testing genetically engineered trees. 　　 Some researchers put special bacteria into trees to help them grow faster and produce better wood. Others are trying to create trees that can clean polluted soil. 　　 Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper. 　　 The Pentagon (五角大楼，美国国防部所在地) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack. 　　 So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered. All this is can be done today because we have a better understanding of tree genomes (基因组). 　　 However, some people fear that the genetically engineered trees will cause dangerous results. They are worried that the new trees will breed with natural species and change the balance of the forest environment.

"It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species." 　　 But researchers insist that science could give nature a fighting chance against both natural and man-made dangers. 　　 They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.

D

With the advent of fast food chains from the West such as McDonald’s, Kentucky Fried Chicken and Pizza Hut, the Chinese are being introduced to a diet that markedly increases the death rate from certain diseases in any population.

The main killers in North America, the degenerative diseases such as heart attack and stroke as well as colon cancer, will become a way of death, not death, not life, in this country if the Chinese do not act quickly and compete with these health destroying food chains.

Scientific studies from all over the world show that a diet high in animal foods such as pork, beef, including sugar, white flour, white noodles and even white rice, undermines one’s health. Deposits of animal fat cling to the walls of arteries, blocking the blood supply to various organs.

This causes diseases in almost every organ, but in particular it damages two of the most vital ones, the heart and brain.

Compare these problems with the excellent health one may enjoy if one consumes good Chinese food. The cook goes out every day, procures great-tasting, fresh vegetables, then cooks them for just a few minutes so that their nutritional value is preserved and afterwards serves them in a most artistic and elegant fashion. Please cling to your traditional ways of eating. They are far superior to those of the West.

Certainly the fast food chains make lots of money, but who wants to fill the pockets of a foreign food chain that proceeds to ruin the health of the Chinese people?

Another reason Western fast food restaurants make money is that the food they serve, which comes from assembly lines, will not attract bugs or spoil easily.

How the Chinese could patronize these fast food places when Chinese cook such delectable food, not just in this country but over the entire world, is beyond my comprehension.

Western restaurants are clean and tastefully decorated. Moreover, these restaurants also do indeed have “good service and an inviting dining atmosphere”. However, Chinese food chains could do likewise if they would organize themselves as the Western chains do.

These lessons in management and décor are the only ones worth learning from the invasion of this country by the Western fast food chains. In other words only imitate the style of the restaurants, not the content of the food or the menus in any way, shape or form.

Do not let the desire for money destroy the wonderful tradition that China has established in producing absolutely fantastically tasty as well as healthful food.
