A Wonder Plant

Every rainy season, the mountain gorillas (大猩猩) of Central Africa migrate to the foothills and lower parts of the Virunga Mountains to feed on bamboo. For the 650 or so that remain in the wild, it’s a vital food source. 1. Gorillas aren’t the only locals keen on bamboo. For the people near the mountains, it’s a valuable raw material used for building houses and making household items. But in the past 100 years, resources have come under increasing pressure as populations have exploded and large areas of bamboo forest have been cleared to make way for farms.

2. All over the world, the ranges of many bamboo species appear to be reducing, endangering the people and animals that depend upon them. A report published by the UN Environment Programme has revealed just how profound our ignorance of global bamboo resources is.

Bamboo is a wonder plant. Its ecological role extends beyond providing food and habitat for animals. Bamboo tends to grow in stands made up of groups of individual plants that grow from root systems. Its extensive root systems are crucial in preventing water loss and soil erosion.3. In India 25% of paper produced is made from bamboo fiber, and in Brazil, 100,000 hectares of bamboo are grown for its production. Because of its flexibility and strength, it has traditionally been used in construction. Bamboo is often the only readily available raw material for people in many developing countries.

4. Ray Townsend, vice president of the British Bamboo Society, says, “Some plants are threatened because they can’t survive in the habitat—they aren’t strong enough or there aren’t enough of them, perhaps. But bamboo can take care of itself-it is strong enough to survive if left alone.5.” When forest goes, it is transformed into something else: there isn’t anywhere for forest plants such as bamboo to grow if you create a cattle grass land.

A. Sadly, this isn’t a single story.

B. It is the physical disturbance that is the threat to bamboo.

C. Until now, bamboo has been viewed as a second-class plant.

D. Without it, their chances of survival would be reduced significantly.

E. Besides, bamboo’s most immediate significance lies in its economic value.

F. More than a billion people rely on bamboo for either their shelter or income.

G. Despite bamboo’s value in economy and ecology, its situation is all the more worrying.

Gorillas(大猩猩) are on the edge of extinction. They are calling on YOU to donate your phone today!

You can now help save gorillas in Africa simply by donating your mobile phone! Coltan is a metallic ore(金属矿石) that is mined both in and out of Africa and can be found within many electronic devices such as mobile phones. The mining of coltan within the Congo River Basin is contributing to forest loss there, and is speeding up the loss of mountain gorillas at a shockingly fast rate. While efforts are being made to deal with this issue, the mining of coltan within gorilla habitat continues. It is very difficult to know which phones contain coltan mined from Africa; however, every phone can help save gorillas when donated to They’re Calling on You.

By donating your phone through the They’re Calling You mobile phone recycling program you are:

●Preventing your phone from going to the landfill.

●Helping Melbourne Zoo raise money to support the Jane Good all Institutes monkey conservation work in Africa through the sale of refurbished(翻新)phones.

●Lessening the demand for coltan mining.

To support the They’re Calling You mobile phone recycling program you can:

1.Visit Melbourne Zoo to collect a postage paid recycling bag, and post your mobile phone to the Aussie Recycling Program. Your phone will be resold to poor community groups.

2.Register your support simply by emailing the registration form to zvfoundation@zoo.org.au or fax it to (03)9285-9377.

Schools can get involved too! Please contact Kate McCabe at Melbourne Zoo by email or phone(03)9285-9471 Discuss adding this program to your course while inspiring students to take action for wildlife.

For further information please contact: Rachel Lowry

Ever wonder how this season’s celebrations affect the environment? Guest blogger Krista Fairles takes an amusing look at this very topic:

The holidays are a wonderful, cheerful time when most people wait for Santa to bring them presents. But I’m not like most people. I spend my time wondering just what the environmental impacts of Santa Claus and his reindeer are, and more importantly, how I can calculate those impacts.

Lately I’ve been particularly curious as to whether Santa’s old sled is a clean green flying machine, or if he should be replacing his 8 reindeer with an environmentally-friendly car.

I should mention that, surprisingly, I was unable to find statistics specific to Santa’s magical flying reindeer, so these calculations use numbers from various sources and may not represent actual pollution caused by Santa and his animals. In other words, don’t complain to the government about the damage Santa is causing the environment based on this article.

Santa’s yearly trip around the globe is 44,000km long, twice the average of a North American driver. If we assume that the magic provides the altitude for this trip, then reindeer power only needs to push Santa’s sled forward. To complete the trip in 12 hours, I estimate they must travel at a speed of about 3100km/h. To travel at this speed, for this length of time, the reindeer need to eat an incredible 980 million calories each!!

So the next question is: how much food is in 980 million calories? Well, if they’re eating corn, they’d need to eat 16,500 lbs each — or 1.6 acres of food. Growing 12.8 acres of corn has its own implications for the environment that we’ll leave for another calculation.

We now need to consider that during the global trip the reindeer are “letting out” some of that corn in the form of methane (甲烷，沼气). A resting cow produces 110 kg of methane per year, so flying reindeer would each let out about 4.8 tons. With methane causing 20 times the global warming damage of CO₂, and the altitude increasing that damage by 1000% that another 20 times, we can put Santa’s round-trip emissions at 15,488 tons. This is much more than the 100 tons an environmentally-friendly car would release on the same trip!

Bad Santa.

1. Which aspect does the writer NOT include in her analyses about reindeer’s influence on environment?

A. Distance covered.                                      B. Calories consumed.

C. Tons of waste let out.                       D. Money spent on food.

2. According to Paragraph 6, how many acres of corn would Santa need to feed 10 reindeer?

A. 1.6.                 B. 16.                           C. 12.8.                        D. 128.

3. Which of the following statements would the writer most probably agree with?

A. Christmas celebrations are really a waste of money.

B. Vegetarians are more likely to survive than meat-eaters.

C. Raising animals has a negative influence on environment.

D. The car industry does less harm to environment than farming.

4. Which of the following words best describes the language style of the passage?

A. Humourous and concerned.                    B. Cheerful and friendly.

C. Academic and formal.                               D. Serious and boring.

5. Which of the following is the best title for this passage?

A. Is Santa driving clean and green?

B. Santa, watch where you’re going!

C. Santa Claus is coming to town!

D. Let’s reduce waste on Christmas celebrations!
