New studies show how food and its production affect the globe and its climate. The process of making a hamburger, for example, requires loss of energy. A cow has to be fed and raised on farmland. And cow waste is a major source of methane（沼气）— 1 especially powerful greenhouse gas. The cow has to be killed. The meat has to be processed and shipped, 2 takes fuel. Most of the cow won’t even be used for meat people eat. By the time a hamburger finally lands o a dinner plate, 3 has made bad effect on the environment.
We can reduce the production of global warming gases by eating less beef.

新思维假期作业寒假吉林大学出版社系列答案The new studies show that fewer than half of the 9th graders in many of the nation’s largest cities, can ever graduate. The studies clearly show that the dropout rate isn’t dropping. And, in particular, the dropout rate isn’t dropping for poor and minority students.
Amazingly, though so many regret the rising dropout rate, our schools continue to lack formal plans—or any plans—to teach students motivation. Most schools have no game plan to ensure that students understand that schooling will be completely necessary. Schools expect youth and children to act as though schooling is important, but they never teach them to believe that.
Years ago, families ensured that the children recognized the value of schooling. But in many modern families, the children may fail to recognize the importance of school life just because these families may actually tell their children that school is not important. Since many families are not motivating their children to be interested students, youth professionals, like teachers may need to provide this training.
Here are some strategies to convince even the most apathetic (无动于衷的) students that they must stay in school.
Ask students if they will ever need to work: The world has changed. 100 years ago, factory work was the booming job, and it required no education. Today, factories are increasingly automated. Most computer-related jobs require education and at least a high school diploma.
Ask students which century they will be prepared for: In 1900, the most common jobs were farm laborer and domestic servant—education not needed. Now, the most common jobs are office and sales staff—education and diploma usually needed. An amazing 6 out of 10 people today work in a store or office.
Ask students to devise a way that the employee could be replaced. For example, the coming trend in fast food is to use computers rather than people to run the restaurant. A prototype is apparently already being tested. The students should discover that most jobs that lack education and diploma requirements may be ripe for automation.

Think about what you had for lunch: Was it a hamburger? A chicken sandwich? Barbecue? What about vegetables? Would it surprise you to learn that what you eat can affect the whole planet?
It can—in a big way. New studies show how food and its production affect the globe and its warming climate. You’ve probably heard of global warming : The temperature is on the rise because humankind has been releasing (排放) amounts of gases into the atmosphere. One of these greenhouse gases is carbon dioxide（二氧化碳）.
What does this have to do with food ? A big part of the carbon dioxide that we put in the atmosphere every year comes from the process of making and eating food. The production of meat contributes a lot of that carbon diode. And much of meat’s contribution comes from beef , which is responsible for releasing even more warming gases into the atmosphere.
The process of making a hamburger ,for example, requires a lot of energy. A cow has to be fed and raised on farmland, and cow waste is a major source of methane (沼气) — an especially powerful greenhouse gas. The cow has to be killed. The meat has to be processed (加工) and shipped to a shop, which takes fuel . Most of the cow won’t even be used for meat that people eat. By the time a hamburger finally lands on a dinner plate, it has made a heavy effect on the environment.
We can reduce the production of global-warming gases by eating less beef .Other kinds of meat like pork and chicken do less harm to the environment—at least in terms of the amount of greenhouse gases released.
All kinds of meat are harder on the planet than vegetables. To grow and eat a pound of potatoes, for example, sends less than one-quarter pound of carbon dioxide into the air. So changing our diet to less meat and more vegetables, as it turns out, may do the world some good.
