1 . You’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.

At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.

Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source (来源) of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part of Von Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.

In a piece from 2018, Von Wong wanted to illustrate (说明) a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped (倾倒) from a truck all at once.

Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.

3 . Last year, 138,000 San Francisco residents used Airbnb, a popular app designed to connect home renters and travelers. It’s a striking number for a city with a population of about 850,000, and it was enough for Airbnb to win a major victory in local elections, as San Francisco voters struck down a debatable rule that would have placed time restrictions and other regulations on short-term rental services.

The company fiercely opposed the measure, Proposition F, with a nearly $10 million advertising campaign. It also contacted its San Franciscan users with messages urging them to vote against Proposition F.

Most people think of Airbnb as a kind of couch-surfing app. The service works for one-night stays on road trips and longer stays in cities, and it often has more competitive pricing than hotels. It’s a textbook example of the “sharing economy”, but not everyone is a fan.

The app has had unintended consequences in San Francisco. As the San Francisco Chronicle reported last year, a significant amount of renting on Airbnb is not in line with the company’s image: middle-class families putting up a spare room to help make ends meet. Some users have taken advantage of the service, using it to turn their multiple properties into vacation rentals or even full-time rentals. Backers of Proposition F argued that this trend takes spaces off the conventional, better-regulated housing market and contributes to rising costs.

“The fact is, widespread abuse of short-term rentals is taking much needed housing off the market and harming our neighborhoods,” said ShareBetter SF, a group that supported Proposition F. Hotel unions have protested the company’s practices in San Francisco and other cities, saying that it creates an illegal hotel system.

San Francisco is in the middle of a long-term, deeply rooted housing crisis that has seen the cost of living explode. Actually, explode is a generous term. The average monthly rent for an apartment is around $4, 000. Located on a narrow outcropping of land overlooking the bay, San Francisco simply doesn’t have enough space to accommodate the massive inflow of young, high-salaried tech employees flocking to Silicon Valley.

As the Los Angeles Times reported, some San Francisco residents supported the measure simply because it seemed like a way to check a big corporation. Opponents of Proposition F countered that the housing crisis runs much deeper, and that passing the rule would have discouraged a popular service while doing little to solve the city’s existing problems.

7 . To know parents’ influence on students’ learning, researchers studied 438 kids and their parents. Before a school year started, the researchers asked parents to write down how anxious they would feel in different situations connected with math like planning their money spending or checking their house’s size. They also checked their children’s math ability and math anxiety in a school year.

The study found kids whose parents were anxious about math learned less math over the school year. And these kids didn’t perform as well on the tests as those who hadn’t been exposed to math anxiety. Besides, these kids also were more likely to become nervous about math themselves. But these kids only “ caught ” that anxiety if their parents had often tried to help with their homework. This is an example of good intentions having a bad result.

The study’s result appeared in Psychological Science. Erin Maloney led the study. As someone who has personally experienced math anxiety, she says, “ I was always very nervous about math, not only taking tests but also learning the new concepts. So I really tried to balk at math, including finding excuses to miss math tests and not wanting to do math homework. ” It was only after she saw how math could be applied to her passion that she started to enjoy math.

Parents with math anxiety should still support their kids as the kids work on math homework, though. But they should know helping kids with schoolwork requires more than just going over facts and concepts. Parents should help kids look for ways to have fun with math, like playing math-based games. When kids have difficulty in learning, encourage them to bravely face it but don’t make them nervous.

What can students do if they’re already nervous about math? Maloney says, “ My earlier study showed that students who wrote about their fears of math for 7 to 10 minutes before taking a math test performed better on that test. After the writing process，many students said their fears weren’t such a big deal. ”

8 . Charity is simple in theory: A heart warms, a hand reaches out. In practice, though, charity can become a troubled mix of motives (动机) and consequences. Giving can be driven by guilt (负罪感), duty, praise, or perhaps the hope that giving will somehow make up for past cruelty (残酷) or ignorance. Too little charity is far less than valuable. Too much can cause dependence, which makes the receiver continuously ask for more.

Giving from the heart is good. But critics (批评家) have long worried about misdirected charity that does more harm than good. In his 2012 book, Harmful Charity: How Churches and Charities Hurt Those They Help (And How to Solve the Problem), Robert Lupton, an experienced social worker of 40 years of community work in inner-city Atlanta, argues that charity must not do for the poor what they can do for themselves.

Due to emergencies such as natural disasters, the afterward financial aid is greatly welcome. Mr. Lupton advocates (提倡) it should focus on the development of self-supporting. The task can be carried out via, for instance, offering microloans (小微贷款), hiring local builders and suppliers, and trying to found self-supported, locally owned and operated factories. What seldom works, he argues, are untargeted handouts from far-off providers and the sudden arrival of inexperienced volunteer-tourists hoping to earn personal reputation by digging wells or mending roofs that locals are perfectly able to take care of themselves.

Getting charity right isn’t easy. But from money raising to the rising in volunteering among Millennials (千禧一代), from the increasing worldwide willingness to give to the efforts by charity organizations to become more effective and fruitful, there is strong evidence that human beings’ ability of taking care of others is growing along with their ability to help without harming.

Charity can be as simple as holding the door for a stranger and as complex as a global campaign to get rid of malaria (疟疾). Charity works best when it returns the weak to strength, and helps a small town shaken by an earthquake get back on its feet. A successful charity is one that eventually is no longer needed.
