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.

It is believed in some ways that the daughter is father’s lover. But my experience has taught me in a different way. For a long time, my father has been a very vague figure（模糊的形象）to me. He was a man of few words, tall but slim and nothing else.
When I was in primary school, my father was never there to pick me up, and he never came to any of my parent-teacher meetings. He was always busy doing projects. I remember when I was in middle school and my head was badly hurt in a PE class. During my operation, my father was nowhere to be found. This hurt me most. At that moment, I considered my father as a cold-blooded man who did not care about me at all.
But things seemed different at my high school graduation ceremony, where I was chosen to represent my class and give a speech. My father, once again, told me he had a business trip in a place outside the city and would be unable to show up（露面）. “Don’t come. I will be very nervous if I see you,” I told him.
I remember my speech went smoothly. After the ceremony was over and I was about to leave. I suddenly noticed a familiar（熟悉的）looking man sitting in a corner of the hall. It was my father! I was so surprised that I rushed to him with tears（眼泪）running down my face. “Well done,” he said. His eyes were also filled with tears.
Later, I found out that my father had managed to finish his work by staying up late, and he drove for eight hours to get back. He had been sitting in the corner because he didn’t want me to see him. My father remembered every word in my speech.
For much of my life, I described my father was a cold-blooded man who only cared about his work. But when I thought deeply aboutthis, it was obviously（明显地）not true. At my graduation ceremony. I could feel my father’s deep love. The fact is that seeing is not believing, and seeing may not be the fact if we don’t perceive（感知）the world with our hearts and minds. There’s no doubt that life doesn’t lack（缺少）love, but sometimes our eyes have trouble seeing it.

Did you know that each day one person in the US throws away 4.4 pounds of rubbish? Almost every month, we throw away our own rubbish in packaging alone. Packaging ( including boxes, bags, etc) comes to our homes with the things we have bought. Several weeks ago, the TV news said that in a city in Italy, tons of rubbish were piled up in the streets, and the smell was rather terrible. What can we do to help? We should get to know the following Rs.
To reduce means to make less rubbish That is one of the first things we all should do for the environment. Reduce your rubbish by doing things like packing your lunch in reusable containers(可再利用的容器)，taking smaller potions(份)at dinner so you don't waste food when you have had enough, writing on both sides of paper, and using less water when taking a shower.
To reuse is to use things again. Think about the bags you get from the store. They can be reused to carry your lunch, to hold your rubbish, or to collect used cans. You can even take them back to the store the next time to carry your things instead of getting a new bag!
Recycling is an important part of keeping our planet clean and green. It can also save energy. Be sure that you don't throw things in the rubbish that can be recycled to make something else. Paper, plastic, cans and bottles can all be recycled, but food, electrical waste and mobile phones can't. When you are not sure whether something can be recycled, go to your parents and teachers for advice.
Follow the three Rs, and every one of us can do something to save the Earth. It is also the best way to save ourselves.
