阅读下面短文, 根据短文内容完成句子。
A vegetarian(素食者)is someone who does not eat meat. Being a vegetarian has become a popular choice. In fact, 1 in every 200 kids in the US is a vegetarian. Most people choose to be vegetarians for many reasons.
First, they believe that a vegetarian diet(饮食)is good for health. It usually has less fat (脂肪)than a diet that includes meat. Vegetarians eat a low-fat diet to stay fit and healthy. A vegetarian diet also provides many vitamins(维生素)that people can't get from meat. These vitamins protect people from some diseases.
Second, many vegetarians are worried about how animals are raised and killed for food. They hope animals can be better treated.
Finally, they think being a vegetarian can help the planet. People use more energy, water and land to raise animals for food than to grow fruit and vegetables. Also, animals put greenhouse gases(温室气体)into the air. These gases cause global warming(全球变暖).
Vegetarians advise people to have just a couple of vegetarian meals a week to make the world a better place.
