1 . As a child, Cruz Avila walked through the forest every day in central Mexico’s Amanalco-Vall de Bravo Basin. She would pick wood and medicinal plants. She also learned to find birds and identify the different trees near her home. Avila learned that listening to a waterfall is a good medicine for the soul and the body.

Several months ago, she and other residents decided to make these walks an attraction for tourists. Their goal is to create a source of income, preserve the forest and support responsible medicine for the soul tourism. In 2021, Avila and other community members attended training as nature guides.

In recent years, residents of the forest communities have suffered from tourism that’s not environmentally sustainable (可持续的). In early April 2022, the communities officially presented their alliance (联盟). One of the people presenting it was Avila, and her voice echoed (附和) the feelings shared by many who are part of this project. “To us, forests are our home,” she said. “We want to take care of them as we take care of our home. We invite hikers and tourists to come to see our house, to get to know and enjoy this place with respect and care.”

Avila said her community has developed a sustainable tourism plan based on hiking and workshops. They also plan to have a viewing platform ready by 2023.

Avila said she plans to start promoting her hiking project, “I’m going to take visitors to a place called El Caballero, and halfway through, with the other neighbors, we’ll offer them a workshop on making pulque and bread,” she said. Pulque is a drink made from a plant that grows in the region.

She believes the tourism project will receive support from visitors. She thinks it will be especially popular with those who are eager to help protect the forests and want to learn about forest communities.

3 . Most of us have heard of the 3Rs: reduce, reuse and recycle. It is the core principle of a sustainable (可持续的) life, but few of us can apply it in our own lives. Now, there’s a “lab” you can explore and discover a way toward living sustainably.

3R Lab is located in Xuhui district, Shanghai. It offers exhibitions, activities and goods that showcase the 3R principle. The key to a sustainable life, according to Vincent T. M. Fong, the 32-year-old from Hong Kong who created the lab, is to make it a long-term promise. “A sustainable life should be sustainable itself in the first place. You can’t lead a sustainable life on a whim. Small and comfortable changes are exactly what you need,” Fong said.

The lab regularly hosts ugly fruit markets, offering these strange fruits which are often thrown away by traditional markets and consumers at a quite attractive price. “They’re thrown away simply because of their appearance. Buying fruit regardless of how they look reduces food waste significantly in our daily life,” Fong commented.

A water tank with two types of straws is another equipment in the lab. “One type is made from normal plastics widely used in our daily life while the other is from PHA, a new replacement for plastics, and the water is sourced from the Suzhou River,” explained Ni Li, an employee of the lab. Visitors can see how the PHA straws degrade (降解) into a thin layer in just one month, while the others remain unchanged.

“Leading a sustainable life does not necessarily mean sacrifice,” said Fong. Consuming ugly fruit and using degradable plastics are small changes that are good for the environment and easy to stick to. Only in this way can the 3R principle become part of our lives, he added.

After working there for six months, Ni, who wasn’t mindful of the 3R principle before arriving at the lab, now uses her cup every time she buys a coffee. “The job has reshaped my life,” Ni said.

Thousands of people are still missing, and the number of deaths     1     (expect) to grow even     2     (high) over the next few days. Foreign aid is being organized for the tsunami-hit countries. However, dangerous conditions and damaged roads will make it difficult to deliver food and     3     (supply).

While some     1    (government) have expressed support for Japan, others have strongly opposed the wastewater release, with many consumers in Asia hoarding salt and seafood amid fears of future contamination.

The start of the release     2     Thursday afternoon sparked a fiery tirade from China     3     described the operation as a “selfish and     4    (responsible) act”. China’s customs department then announced it would stop importing all aquatic products originating from Japan — meaning the ban could potentially limit other oceanic products besides sea food such as sea salt     5     seaweed. The move was aimed at     6    (prevent) “the risk of radioactive contamination of food     7    (safe) caused by Japan’s Fukushima nuclear contaminated water discharge (排放)”, and to protect the health of Chinese consumers, the customs department said in its statement.

Japan has argued throughout the building controversy (争论) that discharging the treated water is safe and     8    (urgent) needed to free up space at the crippled nuclear power plant. The discharge     9    (begin) at 1 p.m. local time, according to state-owned electricity firm — Tokyo Electric Power Company (TEPCO).

10 . Sputnik, the world’s first satellite, was sent up in October 1957. About 100 trillion human-made objects are circling the planet now! The jaw-dropping number was provided by an international team of researchers writing in the journal Science. There are 9,000 active satellites in space, the scientists report. That could grow to more than 60,000 by 2030.The rest of that 100 trillion figure includes everything from used-up rockets and stray bolts(螺栓) to metal pieces and paint chips.

Don’t think a tiny piece of debris(碎片) is harmless. Traveling at 17,500 miles per hour, it can strike a spacecraft hard. The International Space Station is dotted with dents(凹陷) and holes. Astronauts often take shelter in an attached spacecraft to wait out a passing group of space pieces. That way, if the station is severely damaged, they can escape out in a hurry.

For years, this waste has formed an ever-growing mass near Earth. All of these pieces will eventually fall to Earth and burn up in the atmosphere. But we’re replacing the waste more quickly than it’s falling.

The mess we’ve made in space is like the mess we’ve made in the oceans. We’ve had centuries to pollute the oceans. But it has taken just decades for us to do the same in space. That’s why the Science authors include experts in satellite technology and in ocean plastic pollution. Cleaning up space has a lot in common with the challenges of dealing with environmental issues in the oceans.

In March 2022,170 countries signed a global plastics treaty(条约) in the United Nations. This is an agreement to throw away less plastic in the oceans and get rid of what’s already there. There could be similar rules for how many pieces a launch can create. Old satellites could be taken out of space. And technologies could be developed for cleaning up the waste.
