The organic food has gained a lot of [popularity as they are being considered as healthier and tastier.  A fair number of people advocate a large-scale shift to organic farming from conventional agriculture. But this might not seem well-founded.

    Since the mid-19^th century, conventional industrial agriculture has become incredibly efficient on a simple land to food basis. Conventional farming gets more and more crop per square foot of land, which can mean less wilderness needs to be transformed to farmland.

    To make farming more efficient, conventional agriculture uses a significant amount of synthetic fertilizer（合成肥料）each year, and all that nitrogen（氮）enables much faster plant growth. However, the cost is paid in vast polluted dead zones at the months of many of the world's rivers, because much of the nitrogen ends up running off the soil and into the oceans. This also makes conventional farming one of the major threats to the environment.

To weaken the environmental impact of agriculture, improve soil quality as well as produce healthier foods, some farmers have turned to organic farming. Environmentalists have also welcomed organic food as better for the planet than the food produced by agricultural corporations. Organic practices — refusing artificial fertilizers and chemical pesticides –are considered far more sustainable. Sales of organic food rose 7.7% in 2010, up to $26.7 billion—and people are making those purchases for their moral senses as much as their tongues.

    Yet a new meta-analysis in Nature does the math and comes to a hard conclusion: organic farming produces 25% fewer crops on average than conventional agriculture.

    In the Nature analysis, scientists performed an analysis of 66 studies comparing conventional and organic methods across 34 different crop species, from fruits to grains. They found that organic farming delivered a lower output for every crop type, though the difference varied widely. For crops like fruit trees, organic trailed（落后于）conventional agriculture by just 5%. Yet for major grain crops and vegetables – all of which provide the world's main calories – conventional agriculture outperformed organics by more than 25%.

    What that means is that while organic farming may be more sustainable than conventional agriculture, there are trade-offs（此消彼长）with each. So an ideal global agriculture system may borrow the best from both systems rather than upholding merely organic or conventional practices.

You might think people all over the United States have Wi-Fi—-wireless Internet service—and mobile phones. But there is no such service in Green Bank, West Virginia, a tiny town four hours from the U.S. capital, Washington D.C. Fewer than 150 people live in Green Bank, which has two churches, an elementary school and a public library. It is also home to the largest radio telescope in the world.

    There is a ban on Wi-Fi in Green Bank, along with anything else that can create electromagnetic(电磁的)waves. Officials say the waves could disturb the signals the telescope receives.

For many American, a visit to Green Bank is a little like returning to the 1950s. To get there, you must read road signs—because there is no GPS service in the town. People can connect with the Internet through telephones, but wireless service is not allowed.

    The observatory(天文台)is one of the largest employers in the area. The federal National Science Foundation(NSF)spends about ﹩8.2 million a year to operate the observatory, telescope and educational center.

    Jonah Bauserman is a technician. If he supposes there is a signal that is not allowed in the zone, he drives to the house where the signal is coming from and checks it. But once a week, when the device is cleaned, some banned devices are allowed near it.

    People in the town respect the work of the scientists. And they say they are happy to live without Wi-Fi and mobile phones. “You know, instead of sitting here on our phones and other devices we're out fishing and hunting and going to each other's houses.” Everyone knows each other and communication is almost always face-to-face.

Life is difficult.

    What do you think about life? Maybe most people say that life is difficult. But life is no longer difficult once we truly understand and accept it. Most people do not fully see this truth. Instead, they complain about their problems and difficulties as if life should be easy. It seems to them that their difficulties represent a special kind of suffering especially forced upon them or their families, their class, or even their nation.

    What makes life difficult is that the process of facing and solving problems is a painful one. Problems, depending on their nature, cause us sadness or loneliness or regret or anger or fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.

    Yet, it is in this whole process of solving problems that life has its meaning.

    Problems are the serious test that tells success from failure. When we desire to encourage the growth of the human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. It is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, “Those things that hurt instruct.” It is for this reason that wise people learn not to fear but to welcome the pain of problems.

    A family in Florida had a happy Christmas this year thanks to two local police officers, who answered a 911 call only to discover there was no emergency at all.

    When they arrived at the house of a single mother with two children, the officers discovered the younger child, about two years old, was playing with the phone. There were no signs of Christmas or holiday cheer in the house. "They weren't smiling. It seemed like they weren't happy at all. They were missing something," Officer Paramore said. "The mother mentioned that they weren't going to have a Christmas that year. It was pretty obvious that the family was struggling," he said. "So we told each other that something had to be done."

    Paramore and his partner, Barry Ward, left the house with a plan. The next day, they went to a supermarket and bought a tree, lights and some ornaments (装饰物) with their own money. Then they returned to the apartment to deliver some holiday cheer. "They hugged the tree," Paramore said. "I was glad to see that this family was going to have something to sit around and use." The police department posted the video on YouTube, hoping to share the happy news and inspire others.

    The department has received tons of donations and phone calls from people around the country asking how they can help the family. "We are covered," said Stephanie Slater, public information officer for the Boynton Beach Police Department. "We're asking people to do good in their communities on behalf of our officers. We appreciate it very much that people are talking about this after watching the news on TV because they need to see and need to be reminded that police officers are good guys," she said. "They are human beings who have a kind heart and they do things that go unnoticed like this every day."
