1 . One million species face extinction, more than ever before in human history, according to a UN report released in May. And humans should be responsible.
The researchers based the assessment (评估) on some 15,000 sources considering the causes and results of environmental changes over the past 50 years.
The findings are clear and alarming. The researchers have found that about 25 percent of the world’s plants and animals are at risk of extinction. These include sea and land animals. Even the domesticated (驯养的) animals are at risk: Over 9 percent of the domesticated animal species used for food and agriculture might have been lost.
There are some big problems. This rapid decrease of the natural world endangers global food safety and quality of life. For example, about 4 billion people rely on natural medicines, produced by the disappearing species, for their health care.
The researchers identified five drivers responsible for the bad news. They think at the top of the list is the change of land and sea use. The change in ecosystems towards agriculture, aquaculture and other human developments has led to changes in the natural living space of species. It is followed by the direct overuse of creatures (harvesting crops, cutting down the trees, hunting and fishing) and climate change, including rising sea levels and increasing extreme-weather events, wildfires, floods and droughts. The final causes of species extinction are pollution, especially plastics, and the spread of non-native species that can kill native plants and animals. In fact, good ecosystems can promote the growth of species.
The researchers say it is time for humans to act. They think maybe a new global way to save food and refuse waste in our life can turn the tables. Whether that is possible is an open question.

2 . Ecofriendly replacement products for single-use plastics are appearing everywhere. But have you heard of edible (可食性的) straws? Now EQUO, a new eco-friendly company in Vietnam has come up with a natural edible solution to plastic or paper straws.
The edible straws are completely plastic free, nontoxic, chemical free, and 100 percent biodegradable according to a company press release.
“It’s well known that plastic straws are harmful to the environment. Most of the 500 million used every day in America end up in oceans where they pollute water and harm marine life. Currently over eight billion straws pollute the world’s beaches,” said Marina Tran-Vu in the press release. “Although there are some plastic and paper straw alternatives on the market, most are environmentally harmful, and we were also unsatisfied with the quality and lasting of paper straws.”
All of the materials are locally from regions that support sustainable farming according to the company’s website and they struggle to have zero-net influence by” using the power of mother nature”. The name of the company was created by combining “ECO” — meaning environmentally friendly — with “STATUS QUO” — meaning the existent state. EQU stands for creating products that have minimal influence on the environment. The company was first shown on Kickstarter on May 18 and hit their funding goal in only 30 days.
Many countries are banning single-use plastics. The EU banned 10 single-use plastic products including straws that will take effect in 2021. Other items that will no longer be made of plastic include cutlery (餐具), and balloon sticks. These 10 items make up a large percentage of ocean waste that harms marine life.
So do your part, use biodegradable cutlery — you can carry your own , edible straws, and reusable water or coffee cups. These small items can contribute to reducing plastic waste.

5 . The waste management park at Water Beach in Cambridgeshire handles 400,000 tons of recycling every year, and is the biggest centre of its kind in the East of England.
Fran Hawes is standing on the edge of a mountain of dry recycling. She says, “Some think it’s a discouraging thing, but for me personally, it is a huge responsibility.” Fran, who started to do the job at the age of 26, takes her job very seriously. “I am that annoying person at a party who will get everyone’s recycling and make sure everything goes in the right bin,” she admits. “That’s my job. That’s my mission. That’s what I need to do. It allows me to find my leadership style.”
Bin loader Richard Hughes and his colleagues clock on (打卡上班) at the waste service garage in Peter borough at 6:30 and are out emptying bins within half an hour. Richard works four 12-hour days and admits the pay and the condition are not great — but there are three days off which he can spare to his partner and children. His colleague Crystal Teal has been working as a bin loader for two and a half months. “I didn’t feel my last job gave me self-worth and general happiness, so I decided to change and do something completely different,” she says. “I decided to be a binman. It doesn’t bother me that men are mainly doing it,” Crystal adds. “It can be smelly some days, but go home and have a shower, you’ll be all right.”
Their biggest problem? When householders put the wrong material — like rotting food and nappies — in the recycling bins. “It makes me feel angry that they are just putting it out there. We’re doing our job to serve them. We are providing service to take their rubbish away and they can’t do their part to put the right things in,” said Richard. “Any problem has a solution — therefore I’m not afraid of a pile of waste,” Fran says. “To any normal person, this might be intimidating (吓人的). It’s a challenge. But this will be gone by Monday morning.”

6 . San Francisco’s waterfront (海滨) is on the National Register of Historic Places for good reason.
Its beautiful old landmarks, like the Ferry Building and the Bay Bridge, have been seen in many books, TV shows and movies—from the stories and novels of Jack London to the 1970s TV series The Streets of San Francisco. The future of San Francisco’s waterfront, however, isn’t safe.
In 2016, the National Trust for Historic Preservation put part of the city’s shoreline on its list of the U. S.’s most endangered historic places, in part because of the threat of sea level rise. The waterfront landmarks of many cities are under increasing threat from floods and rising sea levels brought on by human-driven climate change. St. Mark’s Basilica in Venice, Italy and the Venice Beach boardwalk in Los Angeles face similar challenges to San Francisco.
“The whole issue of climate change and historic preservation intersects (交织) right at the waterfront,” said Elaine Forbes, director of the Port of San Francisco. As she watched the boats come and go on a sunny afternoon, Forbes said, “Sea level rise hasn’t historically been as much of a threat to San Francisco as major earthquakes.” However, that’s changed. Parts of the main road that runs along the waterfront have flooded from heavy rains in recent years. The state estimates (预估) the water could rise up to about two and a half feet above its present level by 2060, and possibly up to seven feet by the turn of the century.
Now, San Francisco is considering measures to save its historic shoreline. But the growing magnitude and frequency of the climate-related threats, the high costs and effort needed in saving heritage sites, and competing ideas about what’s worth saving and what isn’t, can make it hard for cities to know what to do first.

8 . Zhu Dejun’s first job after graduating from college was as a road design engineer in his hometown, Alshaa League, North Chin’s Inner Mongolia autonomous region(内蒙古自治区). In 2011, when Zhu was conducting a road survey along with his colleagues, he saw a plant that he didn’t recognize. Later, Zhu learned that the plant was a saxaul (灌木梭梭) tree which is an excellent tree species for sand fixation and afforestation (造林) in desert areas. Known as a desert guardian, a fully grown saxaul tree can hold together a 10-square-meter patch of desert land, according to Zhu.
Zhu quit (辞去) his job at the design institute in 2014 and joined a nonprofit organization, the Society of Entrepreneurs and Ecology Conservation, or SEE, in the same year, concentrating on dealing with desertification (沙漠化) .During the past eight years, Zhu has been leading a team from SEE to plant saxaul trees in sandy areas in Alshaa League and other places of Inner Mongolia.
In 2014, the SEE launched a project titled “one million saxaul trees”, aiming to reach that number from 2014 to 2023, turning the desert of more than 133, 330 hectares (公顷) back into a satisfying ecosystem. By the end of 2018, half of the organization’s goal had been achieved. In 2016, Ant Finance cooperated with SEE to introduce the Ant Forest platform, not only encouraging people to choose “a low-carbon way” of shopping, traveling and living, but also to help control desertification.
Through the participation of a greater number of online users, who grow virtual trees, the SEE Foundation, set up in 2008, has been providing subsidies (补助金) for local herdsmen and farmers while also offering technological support to plant saxaul trees in desert areas. Now, Zhu is the head of the foundation’s project to fight desertification. He also gives lectures about saxaul trees and the fight against desertification at schools, hoping to raise awareness among young people.

10 . Overlooking the Davis—Gant Varsity Soccer Field, a bed of overturned soil waits for further development. In a few years, this area will become a natural habitat and a playground for animals and residents. This peaceful area didn’t appear naturally, but through planning and action taken by Catlin Gabel’s Tiny Forest project launched by teacher Patrick Walsh.
Forests typically take hundreds of years to mature, with four stages of growth. “Tiny forests flatten out time through the planting of all four layers (层),” Walsh explained. The end result is a fast-growing, native forest in about 20 years. Over 600 plants from 43 species will be planted in the tiny forest, the first one in Oregon.
Walsh was inspired to build a tiny forest after hearing about this idea, which emerged in Japan and has taken hold in North America. He shared his vision with seniors in his class. The seniors researched tiny forests and made a proposal resulting in Clean Water Services donating 60 trees and $5,000 from the National Oceanic and Atmospheric Administration. Armed with these resources, Walsh and the students started working. “Something I didn’t really expect was the outpouring of students’ enthusiasm. Seeing students from all grades volunteered to contribute to the ‘dirty work’ really blew me away,” Walsh said.
Senior Megan Cover has been at the school since the first grade. “I’ll graduate after working on this project, which is surely sad, but it’s really rewarding and great to be a part of this project and to do my bit. We’re creating this educational space for many young kids,” Cover said.
Walsh summed up his goal of the project, which is to build a place where students can enjoy and learn about nature. “The forest will obviously not solve climate change, but it will deserve the efforts if the kids think about climate change and remember the importance of reforestation and trees when they look outside at the forest.”
