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.

Mom's Recipe for Life

I have a lot of Mom's recipes in a blue box where all my special ones were put，like the

pumpkin pie she made during my growing up years. Even so，the recipe I treasure most is not on any index card， nor did she send it to me in a letter. Instead，she lived this recipe all of her life.

My mother grew up in a small coal mining town in southwest Iowa. My grandfather once told me that she knew no stranger;she considered everyone in that community her friend. That attitude

continued wherever she lived for the rest of her life.

As a teen，I was embarrassed(尴尬的 )every time my mother talked to strangers and offered a smile to everyone in the store or on the city bus. Almost all of them responded(回 应 )with a bright smile of their own. Some spoke，others nodded their heads at this elderly woman who brought a little light into their day.

What really sold me on Mom's approach to life was her experience on the senior bus. The weeks I could not be there， she used this low cost transportation to the grocery store. After her first trip， I asked her how it went.

“ Ha!”she said，“ I got on that bus and what did I see?Thirteen little old ladies and one old

man，and not one word was spoken.”

I wondered how long it would be until the silence on that bus would change. On my next visit，Mom mentioned the 13 little old ladies on the bus and something one of them had told her.

“ Oh，are you talking with them now?”I asked.

“ Of course，”she said. “ One day I climbed up the steps of the bus and before I looked for a

seat，I gave them a big smile and I said，‘ Isn't it a wonderful day? I noticed a few shy smiles.”

Mom didn't give up. She greeted them all each time she got on the bus and before long，the

whole group was laughing and talking to one another. The bus became more than just transportation.

When we went to the various stores，I watched as she smiled and chatted with perfect strangers. Some of them looked like the poorest person you'd ever met，but once Mom smiled at them and started a conversation， most responded favorably. My mother didn't embarrass me any longer. I found myself admiring her.

She's been gone for ten years but I've carried on her recipe for life. It was me who had done the

smiling first and all those people had responded. My mother didn't lecture but taught me by example. She'd given me a recipe for life.
