A vegetarian diet is often praised for its health benefits. Vegetarians usually have lower levels of heart disease, and studies have also shown that they have a lower risk of diabetes(糖尿病)than people who eat meat. However, most people don't realize that a vegetarian diet produces less pollution to the earth.

Researchers from the Union of Concerned Scientists in the US recently studied how people affect the environment. The study showed that eating meat is one of the main ways that humans can change the environment, second only to the use of motor vehicle.

Then, how can eating meat have a negative effect on the environment? For a start, all farm animals such as cows, pigs, and sheep give off methane gas(沼气)by breathing. One cow can produce up to 60 liters of methane each day. Methane gas is the second most common greenhouse gas after carbon dioxide. Many environmental experts now believe that it is more responsible for global warming than carbon dioxide. It is estimated that 25% of all methane released into the air comes from farm animals.

Another way that meat production affects the environment is through the use of water and land. 2,500 gallons of water are needed to produce one pound of beef while only 20 gallons of water are needed to produce one pound of wheat. One acre of farmland used for crop production can produce 40,000 pounds of potatoes, 30,000 pounds of carrots, or 50,000 pounds of tomatoes, however, one acre of farmland used for raising cows can produce just 250 pounds of beef.

Many people now see the benefits of a vegetarian diet, not just for health reasons, but also because it plays an important role in protecting the environment. However, some nutritionists advise against switching to a totally strict vegetarian, or vegan diet. They believe a vegan diet, which excludes(拒绝) all products from animal sources, such as cheese, eggs, and milk, can be short of many necessary vitamins and minerals our bodies need.

Today, many people know that it is important to take better care of their bodies, and to use the earth's resources more efficiently. As this understanding spreads, more people may realize that to help the environment and for the human race to survive, more of us will need to become vegetarian.

No one knows when the first kite was made. The first record of a kite was more than 2,000 years ago in China. Han Xin, the leader of an army, wanted to bring down a king. He decided to dig a tunnel (隊道)into the king’s palace. He flew a kite over the wall of the palace to make sure the length (长度)of its string (线).In this way, he could determine how long the tunnel should be.His men in the tunnel took the kite string with them. When they reached the end of the string, they knew to dig up.

Kites have been flown in Japan for hundreds of years. In the 1700s, kites were flown in autumn to give thanks for a good harvest. They were also flown to send good wishes to couples who had their first son. Today in Japan, kites are often flown as part of a celebration, such as the beginning of a new year. And kite festivals are held each year in many parts of the country.

Kites have been used for scientific purposes in the western world. In 1752,Benjamin Franklin tied a key to a kite and flew it in a storm to find out that lightening was a form of electricity. In the 1890s,Lawrence Hargrave invented the box kite to test ideas about flight. From 1898 until 1933,the United States Weather Bureau (气象局) used box kites to collect weather data. The Wright brothers also experimented (试验)with kites. What they learnt helped them make the first airplane flight in 1903.
