【推荐1】On Sunday, Ecuador held a special vote on whether oil drilling (钻探) should be allowed in Yasuni National Park. The vote was part of a larger election to choose the country’s next president. Nearly 60% of Ecuadorian voters chose to protect the park.

In 2007, to protect the area, Rafael Correa — Ecuador’s president at the time — offered to leave the oil in the ground. In exchange, he wanted the rest of the world to pay Ecuador $3.6 billion. Though Mr. Correa worked hard to find support for his idea, no group offered to pay the money.

In 2016, Ecuador’s state oil company, Petroecuador, began drilling in Yasuni. The company is drilling in a fairly small area known as Block 43. Block 43 makes up far less than 1% of the park, but it produces about 55,000 barrels of oil every day.

But the drilling has upset many people in Ecuador. Yasunidos is a group which works to protect the park. For over ten years, Yasunidos has worked to allow Ecuador’s people a chance to vote on oil drilling in Yasuni. In May, Yasunidos won a court case that allowed them to put the Yasuni drilling up for a vote.

On Sunday, voters were asked if they supported oil drilling in the park or were against it. When the votes were counted, about 59% of the voters chose to stop drilling in Yasuni. Just 41% supported it.

Yasunidos called the vote “a historic success for Ecuador and for the planet!” But the result is a disappointment for Ecuador’s president, Guillermo Lasso. He believes the oil money is extremely important for the country. Selling oil from Yasuni brings in about $1.2 billion a year.

The government won’t be able to ignore or change the results of the vote, and will now have about a year and a half to end the drilling. Petroecuador says it will cost about $500 million to stop drilling and clean up the operation.

Protecting against floods. Wetlands play a crucial role in protecting against floods. The plants and soil in wetlands act as natural sponges (海绵), storing excess water during heavy rainfall or storms.     2    .

Purifying (净化) water. Wetlands have exceptional abilities to purify water. Acting as natural filters, the plants, soil and micro creatures in wetlands remove sediments, excess nutrients and pollutants from water sources.     3    . And the water can be suitable for various uses such as drinking, irrigation and supporting aquatic life. Wetlands are particularly effective in removing harmful chemicals, heavy metals and excessive nitrogen and phosphorus (磷), which can otherwise cause water pollution.

    4    . Wetlands are incredibly productive ecosystems, providing habitats for a diverse range of plant and animal species. The complex and dynamic wetland environments support a lot of amphibians, birds, fish, mammals, reptiles and invertebrates. Many of these species are dependent on wetlands for survival, using them as breeding grounds, feeding areas and nurseries. Wetlands also serve as important stopover sites for migratory birds, offering them crucial resting and feeding areas during their long journeys.

Fighting climate change. Aside from these vital functions, wetlands also play a significant role in fighting climate change.     5    . They act as carbon (碳) sinks, absorbing and storing carbon dioxide from the atmosphere, thus mitigating the greenhouse effect and reducing the impacts of climate change. Moreover, wetlands help regulate local and regional climates by influencing the temperature, humidity and rainfall patterns. 1hey act as natural cooling systems, reducing heat island effects and moderating the local temperature.

However, the world’s wetlands are being lost at an alarming rate. Restoration and conservation projects offer hope that these ecosystems can be saved.

【推荐1】Although a rich literature exists documenting the negative relationship between air pollution and physiological (生理的) health, little has been done to examine the role of air pollution in psychological heath. In the study, titled “Air Pollution Reduces Interpersonal Trust” researchers used three different experimental designs to test their theory that air pollution would reduce one's level of trust in others.

In Study 1, participants were presented with landscape photos that showed either polluted scenes or clear scenes. Those who viewed photos of polluted scenes reported lower scores when completing a questionnaire measuring social trust.

In Study 2, researchers used a “big data” approach, collecting mass information from social media platforms and analyzing it in connection with weather monitoring data. Their analysis showed that polluted conditions were associated with reduced expressions of positive emotions on social media sites, while clearer conditions were associated with stronger positive emotional expressions.

Finally, in Study 3, participants who were asked to read social media posts about poor air quality reported less social trust than those who read posts unrelated to pollution. This makes sense---as air pollution causes negative emotions, people are more likely to focus on others' negative characteristics and find them less trustworthy.

The effects of this study are far-reaching. By reducing trust in others, this study suggests that air pollution can have negative effects on social unity and harmony. Considering widespread air pollution throughout the globe, any effect between pollution and human psychology should be given serious attention.

【推荐1】Colour saturation(饱和) refers to the intensity(强度) of the reds, greens and blues. Photos high in colour saturation make food look fresher and tastier to viewers, which increases their willingness to order the menu items, a new study suggests. “In the restaurant business, these results provide a simple method to increase sales,” said Stephanie Liu, lead author of the study and associate professor of hospitality management at the Ohio State University. “On Instagram, it means using the ‘X-Pro Ⅱ’ filter(滤镜) on your food photos rather than the ‘Early bird’ filter. It costs nothing, so it’s an easy win for restaurant marketers.

In one survey, 267 participants were asked to imagine themselves looking through options on an online food-ordering platform. They were shown photos of a poke bowl, a Hawaiian dish featuring fish, vegetables and sauce over rice. They were randomly asked to view one of the four different photos with either high or low colour saturation and either close or farther away visual distance. The food in the more highly-saturated photos looked fresher and tastier to participants, and that led them to be more likely to purchase the food. But colour saturation had a stronger effect when the food appeared more distant in the photos. “When the food is shown close up, it’s already easy for the viewers to imagine how fresh and tasty the food would be,” Liu said. “Colour saturation is not as necessary.”

In the second survey, 222 online participants were asked to imagine they were looking through photos of pizza from a restaurant near their home. They were told they would either be eating alone or with their family. As in the previous study, the food in the colour-saturated photo was always seen as fresher and tastier and one that people would be more likely to buy. But that effect was stronger for people who were told they would be eating alone. “When people are eating with others, the social experience is a big part of what people look forward to,” Liu said. “But when they are eating alone, they focus more on the food itself.”

“These findings are more important now than ever before,” Liu said. “With people ordering online, restaurants have to post pictures of their food on online ordering platforms. They should pay more attention to the photos they post as they do to the text. Colour saturation is one key element they need to focus on.”

【推荐2】Your chair is your enemy.

It doesn’t matter if you go running every morning, or you’re a regular at the gym. If you spend most of the rest of the day sitting, you are putting yourself at increased chance of heart disease, cancers and an early death. In other words, even if you exercise energetically, sitting for long periods is bad for you.

So what’s wrong with sitting? One is that sitting is one of the most passive things you can do. You burn more energy by chewing gum than you do sitting still in a chair. Compared to sitting, standing in one place is hard work. To stand, you have to tense your leg muscles, and the muscles of your back and shoulders. While standing, you often change from leg to leg. All of this burns energy.

For many people, weight gain is a matter of slow increase. Thus, a little more time on your feet today and tomorrow can easily make the difference between remaining thin and getting fat. So part of the problem with sitting a lot is that you don’t use as much energy as those who spend more time on their feet. This makes it easier to gain weight, and makes you more likely to suffer from the health problems that fatness often brings.

Some people have advanced solutions:replace your sit-down desk with a stand-up desk. Make sure that your television can only operate if you are practising on an exercise bike. Replace your office chair with a therapy (治疗) ball: this too uses more muscles, and more energy, than a normal chair, because you have to support your back and work to keep balanced. But whatever you choose, know this. It is clear: be careful of your chair.

【推荐3】Archaeologists in Germany have uncovered some of the earliest evidence of the use of clothing, with newly discovered cut marks on a cave bear’s paws suggesting the prehistoric animal was skinned for its fur some 300,000 years ago.

The discovery in Schöningen, northern Germany, is exciting because despite the written records of cave men and women covered in fur in some popular cultures, very little is truly known about how early humans clothed their bodies. Fur, leather and other organic materials typically can’t be preserved beyond 100,000 years.

“The study is significant because direct evidence of prehistoric clothing is scant and we know relatively little about how humans in the deep past were protecting themselves from cold winters. From this early time period, there are only a handful of sites that show evidence of bear skinning, with Schöningen providing the most complete picture,” said study author Ivo Verheijen from Tübingen University in Germany.

Cave bears were large animals, about the size of polar bears, that went extinct about 25,000 years ago. The cave bear’s fur, which has long outer hairs that form an airy protective layer, and short, dense hairs that provide good insulation (隔离), was suitable for making simple clothing or bedding.

The clothing in the site probably wrapped the human body without careful tailoring. The eyed needles needed to sew more excellent designs didn’t emerge in the archaeological record until about 45,000 years ago.

“We found the cut marks on the cave bear’s hands and feet where very little meat or fat is present on the bones, which argues against the cut marks originating from the butchering of the animal,” Verheijen said. “In these locations, the skin is much closer to the bones, which makes marking the bones inevitable when an animal is being skinned.”

The Schöningen site in Germany is most famous for the discovery of the oldest known wooden weapons that were used to kill prey 300,000 years ago.

But it’s still challenging to figure out exactly when ancient humans began wearing clothing. Genetic studies of lice (跳蚤) indicate that clothing lice separated from their human head louse ancestors at least 83,000 years ago and possibly as early as 170,000 years ago, which suggests humans were wearing clothes before major migrations out of Africa. Bone tools found in what’s now Morocco suggest that humans were processing animal skins 90,000 to 120,000 years ago.
