【推荐1】They may have text, email, Facebook and Twitter, but young people are still lonelier than any other age group. The Loneliness in New Zealand report, published by Statistics New Zealand, shows under 30s are more likely to feel lonely than older people because loneliness decreases with age. Loneliness and poor mental health were strongly related across all ages. Young people were not as likely to feel lonely because of financial hardship, but among older people, lack of money was a significant influence on loneliness. Women were more likely to feel lonely than men.

Philip Walker, spokesman for the General Social Survey, said because it was relatively new it was hard to know whether loneliness among young people was a new trend. But overseas research has found that levels of loneliness in youth today are growing.

Walker said the finding needed more exploration, including looking at the role of technology and social media. “It could be that people’s expectations of connection have gone up, so we expect increased levels of connection,” he said. “While technology like cell phones could help young people stay connected, on the other hand for those who do get bullied (欺辱), especially bullied online, it’s quite isolating. A lot of the time potentially it is a big contributor to loneliness.”

Figures from online dating website FindSomeone also confirmed more young people were looking for love. Manager Rick Davies, said younger dating hopefuls were the fastest growing group on the site.

Mr. Davies noted that since the report data was collected in 2010 there had been huge growth in smart phones, which meant people were online even more. He believed online tools, such as Skype, could help people stay connected. “People can keep in touch with a wide range of friends from all over the world much more easily now. It’s like you’re sitting in your living room having a chat with them.”

Bemardine Reid, operations committee chairwoman for Samaritans, which operates a free helpline, said many of their calls came from people who were lonely. “It might be that they’ve got some problem, just like all the things people would normally talk to a friend about, but people who are alone lack those normal contacts.” (交流)

The Statistics New Zealand report also showed people who didn’t have face-to-face contact with family and friends were more likely to feel lonely, as were those who lived alone.

【推荐3】Efforts to preserve the Amazon rainforest, which supports immense biodiversity and locks away tons of climate threatening carbon, are growing more urgent as the ecosystem’s destruction speeds up. Indigenous (当地的) peoples have been trying to protect the region by patrolling (巡逻) their territorial boundaries for illegal activities. But rapid deforestation continues.

A recent study shows that combining on-the-ground monitoring with satellite data and smartphone technology could help put the brakes (刹车) on Amazon deforestation —and potentially that of forests elsewhere.

Illegal logging, agriculture and coca cultivation particularly threaten the Amazon in the Peruvian Indigenous communities and outsiders are often the culprits (罪魁祸首). The research team wondered if providing training for local people to use satellite based “early deforestation alerts (警报)” could help. The scientists cooperated with 76 Indigenous communities, 36 of which participated in using these alerts to watch over the forest. Over the next two years these trained participants were paid to work as forest monitors and received monthly alerts via the app when satellite data indicated local forest losses. Monitors investigated alerts, patrolled for deforestation in other areas and reported confirmed tosses back to their communities, which decided whether to deal with the culprits on their own or inform state authorities.

The researchers analyzed the same forest-loss satellite data from the given time period in all 76 communities. They found the early-alert program reduced forest loss by 8.4 hectares in the first two year — a 52% reduction compared with the average loss in the control communities.

Experts say this approach to tackling Amazonian deforestation looks promising. “Would this work in all communities that have high risk of deforestation? Given the results, it’s worth a try,” says Catherine Tucker, a researcher at the University of Florida. “But some communities may not have access to the resources needed for such a program, or their territories may hold valuable minerals that would increase the risk of deforestation by outsiders despite monitoring efforts,” wrote Francisco Hernandez Cayctano, a community member involved in the research, “we as Indigenous peoples ask the world for support.”

【推荐1】The government of Singapore has created a highly developed system that turns wastewater into drinking water. The system involves a network of tunnels and high technology treatment centers.

The system helps reduce ocean pollution, as only a small amount of the treated water is sent into the sea. The United Nations estimates that 80 percent of the world’s wastewater flows back into the oceans without being treated or reused.

Singapore has few natural water sources. The island nation has long had to depend mostly on supplies from neighboring Malaysia.

Low Pei Chin, an expert, told reporters, “Singapore lacks natural resources, and it is limited in space, which is why we are always looking for ways to explore water sources and stretch our water supply. One major plan is to collect every drop and reuse endlessly.”

Parts of the water treatment center are underground. Wastewater enters the center through a 48- kilometer tunnel that is linked to sewers. The center contains a large system of steel pipes, tubes, tanks, cleaning systems and other machinery. It can treat up to 900 million liters of wastewater a day.

In one building, a network of air flow systems has been put in place to keep the air smelling as fresh as possible. Waste that arrives at the plant goes through a cleaning process before powerful pumps send it flowing to areas above ground for more treatment. There, the treated water receives additional cleaning. Bacteria and viruses are removed through highly developed cleaning processes and then disinfected with ultraviolet radiation (紫外线).

Singapore is also in the process of expanding its recycling system. The country will add another underground tunnel and a major water treatment center to serve the western half of the island. Officials expect work on the center to be completed by 2025. By the time the expansion is finished, Singapore will have spent about $7.4 billion on its water treatment systems.
