Facebook is helping to save the environment. So is your iPhone. Surprised? I was too when I first realized it but after I thought about it for a while, I totally believed it was true.
Let’s start with your iPhone or other smart phones for that matter. How is that helping the environment? Think about it. Before, you used to have your phone, your camera, your mp3 player and your DS or PSP. Those are four electronic items. Each of these needs charging. Each of these came in its own packaging. Each of them was shipped individually from where they were made and each was likely picked up by you in separate trips. That’s four times the carbon emission per product. By simply buying an iPhone you have cut down your carbon emission by three quarters.
That’s not all. The digital content distribution provided by iTunes Store allows us to buy music electronically. This means there is no CD, no manufacturing carbon footprint, and no shipping carbon footprint. The eBooks stores mean that we no longer have to ship books all over the world. Let’s face it. Books are heavy and take up a lot of space (compared to a CD anyway). There’s a lot of carbon involved in making and shipping them. Even though the wood to make the paper usually comes from sustainable sources, the reduction in carbon is significant. Downloading apps mean that you save on all the games packaging and harmful chemicals involved in the production of all of the CDs and manuals. Another winner.
Facebook is another example of where physical products are being converted into digital products. It is easy to upload hundreds and thousands of copies onto Facebook and have everyone cheek them out. To do this before you’d have to print hundreds of copies and send them physically to people. Granted, you might not want to send all your photos around but digital cameras and Facebook allow the photographers and the viewers to make decisions about which photos are worth keeping and which are not.

Social networking isn’t only for the under 40s. More than 25 percent of Americans 50 years and older stay connected using sites such as Facebook, MySpace and Twitter, according to new research.
“The latest data tells us that more and more social networking is becoming a part of everyday life for Americans 50 plus,” said Kevin Donnellan, the chief communications officer at AARP, which released the report.
Nearly a quarter of older Americans are on Facebook and 73 percent said they use it to stay in touch with relatives, but not just their children and grandchildren. “They are using the Internet to keep up with the world and the people who are important to them,” said Jean Koppen, the author of the report. She added that older adults are also on Facebook to stay connected, not only with their family, but with their friends and those in the same age group. Almost 50 percent of older adults were introduced to the social networking sites by a family member, mainly a child or grandchild. “Just under one-fifth of adults aged 50 and older say they do not use the Internet,” according to the report.
The findings are based on a telephone survey of 1,863 adults. In addition to keeping up on Facebook and Twitter older adults are aware of the latest technology. Eighty-three percent had heard about the Apple iPad and 11 percent intended to buy one.
Despite the popularity of the Internet among the over 50s, they still mostly go to print newspapers and magazines for news. Only one percent said they followed blogs.
44. What is the main idea of the text?
A. Social networking is becoming popular among older Americans.
B. Social networking isn’t for the under 40s in the U.S.A.
C. American old people’s way of life is quite fashionable.
D. Facebook, MySpace and Twitter are the most popular websites in the US.
45. Which of the following statements is TRUE according to the passage?
A. 85% of Americans 50 plus choose the Internet over print media.
B. About 20% of adults aged 50 plus have access to the Internet.
C. Three quarters of the people surveyed got to know the Internet through their family.
D. About 460 people in the telephone survey often use Facebook.
46. Where does the text probably come from?
A. A novel. B. A technology guide.
C. A newspaper. D. A student’s research paper
