Labels placed on fast food items stressing their high climate impact may influence consumers to make more sustainable (可持续的) choices, new study results show.
Food accounts for around one-third of all human-made greenhouse gas emissions, while animal-based foods like red meat and dairy products make up a large part of these emissions.
Researchers carried out a randomized clinical trial with more than 5,000 participants to determine whether calling attention to red meat’s climate impact could change consumer menu selections.
Individuals were shown a simple online fast food menu and asked to select an item for dinner. A control group received a menu with a quick response code label on all items and no climate labels. Another group received a menu with green low-climate impact labels, positively framing choices like fish, chicken, or vegetarian choices. The third group received a menu with red high-climate labels on items containing red meat, negatively framing the choices.
Results showed 23 percent more participants in the high climate label group ordered a sustainable, non-red meat choice, and 10 percent more in the low-climate group ordered a sustainable choice, compared with controls.
“In the United States, meat consumption, red meat consumption in particular, often exceeds (超过) recommended levels based on national dietary guidelines,” researchers wrote in the study. “Shifting current dietary patterns toward more sustainable diets with lower amounts of red meat consumed could reduce diet-related greenhouse gas emissions by up to 55 percent.”
Extra red meat consumption can also be harmful to human health and has been linked with increased risks of diabetes and certain cancers. Fast food restaurants are a key source of red meat in many Americans’ diets, authors noted, adding more than one-third of U.S. individuals consume fast food on a given day.
“These results suggest that menu labeling, particularly labels warning that an item has high climate impact, can be an effective strategy for encouraging more sustainable food choices in a fast food setting,” said lead study author Julia Wolfson, an associate professor from the Johns Hopkins University Bloomberg School of Public Health.

American Congress first passed the law in 2002. Stores have had to label seafood by country of origin since 2005. But industry pressure delayed other requirements until last week.
Products that must now be labeled include fresh fruits and vegetables, muscle meats and some kinds of nuts. But the rules are complex, and many foods are excluded. For example, organ meats are free to be labeled. So are processed foods, including cooked or smoked food.
The United States has imported more and more food in recent years to save money and expand choices. Country-of-origin labeling has become more common lately but has still been limited in many stores.
Food safety is one reason why some shoppers pay close attention to where foods come from. For example, when a large number of people recently got sick from salmonella, officials blamed peppers from Mexico. Yet the last big food scare involved spinach (菠菜) grown in California. But labeling is also a way for people to know they are getting what they want. Some want to buy local foods or foods from a particular country.
The country-of-origin labeling law gives stores 30 days to correct any violations (违反) that are found. Stores and suppliers that are found to be deliberately violating the law could be fined 1000 dollars per violation. Federal inspectors are not to take action to enforce the law for six months to give time for an education campaign.
Some food safety activists say they are generally pleased with the law. They call it a good step that will give people more useful information.

【推荐3】Parents can cut the chances of their children getting fat simply by keeping them longer at table. Just three minutes extra at a family mealtime could help prevent child obesity. Research found that among poor families, the extra minutes at mealtimes made great improvement of a normal weight for the youth. The factors are likely to be communication and the importance of a scheduled mealtime.
Dr Barbara Fiese said, “Children, whose families have a 20-minute meal over four times a week, weigh less than kids who leave the table after 15 to 17 minutes. Over time, those extra minutes per meal add up and become really powerful.”
The researchers studied 200 family mealtimes, testing the effects of factors and mealtime behavior of families with children in primary school. They found that families, who said that shared mealtimes were an important part of family life and had special meaning for them, were less likely to have an obese child. Similarly, families, who talked more together and interacted more positively during the meal, were more likely to have healthy-weight children.
Teaching low-income families how to make the most of family mealtimes was a wise idea. Dr Fiese said, “This is something we can target and teach.” She added, “It’s also important to recognize the increasing differences of families and their sometimes complex living arrangements that may challenge their abilities to plan ahead and arrange a single time to communicate with each other.”
Families in poorer US neighborhoods faced a lot of problems, including poor access to healthy food. But even so, regular high quality family mealtimes made a difference to the children’s weight. Dr Fiese said, “Three to four extra minutes per meal will make a healthy weight more possible.”

【推荐1】Green is not always referring to the color. In some cases, it is the term used for being environmentally friendly. If you’ve been looking to replace your furniture, consider going green because environmentally friendly furniture offers many benefits. Here are a few tips to get you started on your hunt for the perfect eco-friendly furniture.
First, environmentally friendly furniture isn’t harmful to your health. Also its manufacturing process doesn’t cause damage to the environment in any way. Besides, by purchasing eco-friendly products, you prevent deforestation and global warming to some extent in your own way. You do your part in protecting the environment. Environmentally friendly furniture is cost-effective as well.
The materials that are used in furniture are what make them green. Materials can be good for the environment either because they are materials that are considered renewable resources or they are all natural. A lack of chemicals and toxins (毒素) in green furniture also means it is a better choice for the environment. It may be hard to imagine that a sofa or a table could actually be a green product but they really can be depending on what they’re made of.
There are a lot of renewable sources that manufacturers could use when building the furniture, so you should be keeping an eye out for them. Bamboo can be an excellent replacement for wood and can also replace plastics and metals in some furnishing. Cotton is a sofa fabric that is safe for the environment and it can be replenished (补充) often. Hemp is also a renewable source that can be used for fabric and twine.
Recycled materials also can be made into green furniture. Metals can be recovered and remade into new things such as frames and foundations for sofas. Recycled plastic can also be made into furniture such as tables and chairs. Touching up old furniture instead of buying new items is very cheap way to be green. Yard sales and second-hand stores sell furniture too and buying the used means new things won’t be made, so no more damage has to happen to the earth.
Therefore, when you want to hunt for the perfect environmentally friendly furniture, you should try to know the type of materials which are used in building the furniture.

【推荐2】Have you imagined that planting trees can make a big difference? People say that one man can’t make a difference, but Abdul Samad Sheikh, a 60-year-old rickshaw (人力车) driver from Bangladesh, has proved that doing a small thing over a long period of time can mean very much. He has planted at least one tree every day since he was 12 years old, which means that he has so far planted a small forest of over 17,500 trees. Imagine if everyone followed his example.
Abdul has worked as a rickshaw driver for most of his life. He makes a little money from his job, which is only enough to put food on the table for his family, but he somehow tries to also buy at least one tree every day. He considers it his duty to the world. Mostly he plants them on government land so nobody can cut them down later. He also waters them, and if he sees anyone cutting a tree, he blames them.
Abdul, his wife Jorna, and four of their children live in two old houses, on a piece of land that is owned by the Faridpur deputy commissioner’s office. They have no land of their own.
Sometimes, she commands him not to plant trees but he doesn’t listen. Abdul’s 30-year-old son, Kutub Uddin, has never told his father not to plant trees, because he thinks his father does a good thing for society.
Abdul’s neighbors all know about his daily habit, and praise his work. Whoever can ask of him anything, he will do his best to help. Therefore, Abdul is loved by neighbors.
For his efforts, Abdul Samad Sheikh was recently honored by The Daily Star, and given $1,253 to help him build a better home for his family. The Daily Star wished everyone to follow his example, and protect the environment.
“I can’t do it alone. I need the help of you all,” Abdul said in his speech.

【推荐3】Overtourism happens when the number of tourists or the management of the tourism industry in a destination becomes unsustainable (不可持续的). When there are too many visitors, the quality of life for the local community can be affected, the surrounding natural environment can become worse, and the quality of the tourists’ experience can fall.
However, in most places, overtourism is not a hopeless situation. Destinations all over the world have already showed ways to overcome the obstacles presented by overcrowding and unsustainable tourism management.
East Africa, for example, has turned the gorilla (大猩猩) visiting into a once-in-a-lifetime experience by putting limits on daily permits, while maintaining conservation efforts inside native forests and offering jobs to local guides. In Antarctica, the Antarctic Treaty limits the size of ships that land there as well as the number of people they can bring ashore at one time; it also requires a minimum guide-to-tourist ratio (比率) while tourists are off the boat.
Local governments, of course, are largely responsible for keeping sustainability in the tourism industry. But approaches to reducing the negative effects of overtourism can come down to individual travelers as well. One of the best ways is to become a responsible tourist by looking outside of the mainstream travel destinations. Consider outer cities or less-visited attractions to avoid crowds altogether while experiencing the destination’s daily culture outside of the popular areas. There are countless places that want and need more tourists to explore.
If you just have to visit the popular destinations, consider visiting during their off-season. People who rely on tourism to live on need support during the off-season more than any other time of year. Besides, it will save money since accommodations and flights tend to be cheaper. Even better, off-season travel puts less pressure on the environment.

Drayton believes that anyone can become an agent for change. The important thing is to simply give yourself permission. If you see a problem that you care about, you can help solve it. The young in particular are willing to accept this concept because at heart every child wants to grow into a happy, healthy, contributing adult. In fact ,It is many young people's ambition to set up programmes or businesses that improve social conditions. An excellent example is an Ashoka project started in 1995 in Dhaka, which handled the rubbish problem facing the city ,helped local farmers and provided an income for poor people there .
When Masqsood and Iftekhar began to study the problem of all the uncollected rubbish that lay in Dhaka’s streets. Attracting tats and disease , they discovered that 80% of it was natural waste . So they educated the poor people in the city to compost (把……制成堆粪)this waste . They knew that they would have a market for the end product because local farmers were struggling with chemical ferntilisers (化肥) which were expensive and had reduced the natural minerals in the soil over the years . At first , they were refused ,but once they were able to persuade that there was money to be made , the project took off. In 2009 sales were $14,000.
Drayton is optimistic that in ten years Ashoka will be making really serious, practical progress in bringing about social change by changing the way we look at economic development.

【推荐2】While retiring ahead of time may be easier on the body, a new set of research has found that it may not be so beneficial to the mind. The study, carried out at Binghamton University, finds that an early retirement can speed up the usual rate of cognitive (认知的)decrease among the elderly.
The research team studied China's new rural pension (退休金)system, as well as China's most recent Retirement Longitudinal Survey ( CHARLS), in order to look into the effects of early retirement and pension benefits on individual cognition among adults over the age of 60. After going over all of the data, the research team noted a clear direction: people receiving pension benefits were experiencing much more rapid mental decline (智力下降)than those still on the workforce. Surprisingly, women seemed to experience even sharper mental decline after retiring early. Overall, the results support the view that decreased mental activity speeds up cognitive decline.
Nikolov, the lead researcher, had actually carried out former studies that found retirement led to a number of physical health benefits for retirees, such as improved sleep patterns, less stress, and reduced alcohol consumption. However, retirement also usually goes with a decline in social activities and less communication with people, which has also been linked to cognitive decline.
“For cognition among the elderly, it looks like the bad effect on social connection is more than the good effect of the program on fitness and sleep,” Nikolov says. “ Or social connection may simply be the single most powerful factor for cognitive performance in old age.”
The research team are hopeful that their findings will be considered by older adults when thinking about retirement, but perhaps more importantly, they hope that policy makers in developing countries take note while drawing up new pension plans. They suggest building social get-togethers and work shops for recent retirees to help cut down the decline in social communication and creative thinking that often comes along with retirement.

【推荐3】Choice of seating in the lecture hall can influence a college student’s grades, a study suggests.
Lectures are important in higher education. Researchers from Sheffield Hallam University in the UK examined students’ reasons for choosing particular seats in a lecture hall, and studied how seating positions influence student performance.
“Interaction (互动) is a key part of learning and knowing who the students are interacting with can be a great benefit when designing activities,” said David P Smith of Sheffield Hallam University.
Many students preferred being able to sit with their friends, while others were more concerned with either attracting or avoiding the lecturer’s attention. Some students chose seats that allowed them to see and hear clearly, while others picked seats that are easy for them to leave and that make them feel less anxious, researchers said.
Friendship groups who sat together tended to achieve similar grades, and students who sat alone at the edges tended to do worse than average.
Lecturers may be able to use these findings to provide assistance to anxious students, and to support the learning of all students by encouraging interactions between the different groups.
Appraising (评估) classroom rows based on academic success, some professors have found out that the front rows are usually held by outgoing scholarly students.
“I notice the more prepared and active students sit in front rows.” said Dr. Chris Hammons, dean of the College of Arts and Humanities and chair of the department of government (London). Perhaps more importantly, the front row may be the ideal location for shy, timid students who have trouble paying attention. Also, sitting closer to the front of the room does have an effect on student-teacher interaction, which is linked to greater academic performance. According to a study published in 2013, students’ grades lowered by 0.1 point for every row further back students sit.
