You’ve heard that plastic is polluting the ocean — 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.

In early summer, the mountains and fields of Guizhou provinces Miao villages are dressed in fresh robes of green. Everywhere, vigour and vitality shine.

Red roofs, gray walls, green trees and grass, along with placid water in the fields, paint a bright and colorful picture of Bayi village in Qiandongnan Miao and Dong autonomous prefecture.

The layers of terraced fields are a masterpiece of farming culture handed down by the ancestors of local Miao residents. Villagers plow fields and transplant rice seedlings.

Researchers say they have translated the meaning of gestures hat wild chimpanzees (黑猩猩) use to communicate. The say wild chimps communicate 19 specific messages to one another with a vocabulary of 66 gestures The scientists discover this by following and filming groups of chimps in Uganda and, and examining more than 5,000 incidents of these meaningful exchanges.

Dr Catherine Hobaiter, who led the research, said that this was the only form of intentional communication to be recorded in the animal kingdom. Only humans and chimps, she said, had a system of communication where they deliberately sent a message to another group member.

“That’s what’s so amazing about chimp gestures,” she said. “They’re the only thing that looks like human language in that respect.”

Although previous research has shown that apes and monkeys can understand complex information from another animal’s call, the animals do not appear to use their voices intentionally to communicate messages. This was a significant difference between calls and gestures, Dr Hobaiter said.

Chimps will check to see if they have the attention of the animal with which they wish to communicate. In one case, a mother presents her foot to her crying baby, signalling: “Climb on me.” The youngster immediately jumps on to its mother’s back and they travel off together. “The big message from this study is that there is another species (物种) out there that is meaningful in its communication, so that’s not unique to humans,” said Dr Hobaiter.

Dr Susanne Shultz, an evolutionary biologist from the University of Manchester, said the study was praiseworthy in seeking to enrich our knowledge of the evolution of human language. But, she added, the results were “a little disappointing”.

“The vagueness of the gesture meanings suggests either that the chimps have little to communicate, or we are still missing a lot of the information contained in their gestures and actions,” she said. “Moreover, the meanings seem to not go beyond what other animals convey with non-verbal communication. So, it seems the gulf remains.”
