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 effect the whole planet?

___71 ___ Last week, scientists presented new studies showing how food and its production affect the globe and its warming climate. The researchers had some bad news for meat-eaters. They also offered some suggestions for how to eat in a more environmentally friendly way．

     ___72____ For many years, scientists have warned that our planet is getting warmer. If current trends continue, animals may start to die off and life could get very difficult for everyone. The temperature is on the rise for more than a century, and human kind has been releasing massive amount of gases into the atmosphere，called “greenhouse gases”. ___73____ One of these greenhouse gases is carbon dioxide(二氧化碳)．

    What does this have to do with food? A big chunk of the carbon dioxide that we put into the atmosphere every year comes from the process of making and eating food. The production of meat contributes a lot of that carbon dioxide. For example, a cow has to be fed and raised on farmland, and cow manure(糞肥) is a major source of methane(甲烷) ----- an especially potent greenhouse gas．The meat has to be processed to a consumer, which takes fuel．

___74___To grow and eat a pound of potatoes，for example, sends less than one quarter pound of carbon dioxide or equal warming gases into the air．___75___

A. It can ---- in a big way．

B. You’ve probably heard of global warming．

C. Global warming is a problem that the world is solving．

D. These gases surround the planet and keep heat from escaping the atmosphere．

E. Producing the production of meat can consume more energy and natural resources.

F. All kinds of meat on the planet, the scientists reported, are harder than vegetables.

G. So shifting our diet to less meat and more vegetables may do some good for the world．

   You might think that “global warming” means nothing more than a rise in the world’s temperature. But, rising sea levels caused by it have resulted in the first evacuation(撤離) of an island nation—the citizens of Tuvalu will have to have their homeland.

During the 20th century, sea level rose 8-12 inches. As a result, Tuvalu has experienced lowland flooding of salt water which has polluted the country’s drinking water.

Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.

Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions(導(dǎo)致溫室效應(yīng)的氣體排放), which are a main cause of global warming. “By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years,” Laupepa told the BBC.

Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.

Tuvalu is not the only country that is vulnerable(易受影響的) to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an “endangered nation”.

56. The text is mainly abou_________ .

       A. rapid changes in earth’s temperature
