2 . Damon Carson calls himself a matchmaker (媒人) of the never-ending waste of American society, trying not to pair people with people, but things with people.

In the late 1990s, Carson was on break from business school in Vail, Colorado, when he discovered the vast world of waste. He began thinking about creating a secondhand store that would sell old materials and keep them out of being wasted. As a result, in 2010, his company, Repurposed Materials appeared.

For nearly ten years, his company, Repurposed Materials, has not been looking to recycle the waste he gets — breaking it down to make something new — but rather finding new homes for thrown-away goods in their original forms.

Carson, a husband and father of three adult children, is far from wasteful. Frugal is how he describes himself. The clothes he’s wearing all came from a charity shop; his truck was bought with 290, 000 kilometers driven.

“Why break something down, why melt something down, if it still has value?” he asks. An old oil-field pipe might be melted down and turned into a car bumper, but it still takes an amount of power to finish the complete change. Why not leave it as a steel pipe? Why not turn it into a fence post on a farm? The only cost is transport.

American industrial facilities create and throw about 7.6 billion tons of unwanted industrial materials every year. For the moment, Carson’s unique business finds new lives for millions of kilograms of industrial waste every year.

When garden designer Jane Gates moved to the Sussex countryside in 2015, she fell in love with a traditional black barn conversion(改建的房屋), and set about creating a droughts-resistant garden around it.     1    she didn’t know was just how quickly her garden would become relevant to today’s changing climate.

Over the years, Gates       2    (experiment) with plants that suit this dry and hot place and made some interesting     3    (discover). Surprisingly, some plants, known for loving water, have proved    4    (adapt) to drought. Others have struggled. However, many plants specifically     5    (choose) for drought tolerance have enjoyed the heat.

Gates’ garden is a big gravel(砾石)one.       6    occasion she stands by the floor-to-ceiling windows and enjoys the scene. Gravel     7    (use)as a layer(层)for the plants to grow through, joining the paths with the planting. The feeling is of a relaxing, natural-looking space, with the light colour of the gravel    8    (compare) beautifully with the black of the barn. Gates recommends gravel as a cover on the top for    9    reason that it locks water in the soil below in summer, while keeping it away from plants in winter, which can damage them. This helps some plants do a bit    10    (well) in adapting to climate extremes.

5 . Windows open? Fans on? Ready for another water break? For schools across Greater Toronto, the extremely hot temperatures provided some lessons in how to beat the heat—or at least attempt to—without air conditioning. It wasn’t easy. With some classroom temperatures getting close to 40℃—one teacher even handed out temperature meters to see how hot it got—both students and educators were red-faced and bathed with sweat all day.

The extreme weather had some parents wondering if their children should be spending most of the day inside hot schools, and a few chose to keep them home. Very few schools across Greater Toronto are air-conditioned. There are no rules or requirements that schools shut down as the temperature rises.

At Bowmore public school, near Coxwell Ave. and Gerrard St. E, teachers arrive at 7 am and open all the doors and windows to circulate fresh air. The windows at the school, replaced in stages over the past few years, swing in at the top, and out at the bottom to provide better air flow.

“Is it hot? Yes. Is it something that makes us feel uncomfortable? Yes,” said Headmaster Lilian Hanson. Despite that, she said she’d never advocate for air conditioners in schools, which are expensive and would consume the city’s electric power. She’d rather see more gardens, more trees—more natural solutions, more sustainable choices.

“We are teaching kids to make good choices,” she said. “Social responsibility is the key.” Students from kindergarten to Grade 8 seek pleasant places under trees and in the outdoor peaceful garden during the break time between classes and after school as the trees there provide much-needed shade. Teachers also take classes with students out there during the day. And kids do get the message about staying cool. Students are reminded to dress in cool clothing. When Hanson arrived at work in a dark-colored dress, a student asked her: “What were you thinking wearing a black dress on a day like today?”

6 . Europeans got more of their electricity from renewable sources than fossil fuels for the first time last year, according to an annual report from Ember and Agora Energiewende.

The report, which has been tracking European Union’s power sector since 2015, found that renewables delivered 38% of electricity last year, compared to 37% delivered by fossil fuels.

The shift comes as other sources, such as wind and solar power, have risen in the European Union. Both sources have nearly doubled since 2015, and as of last year accounted for one-fifth of electricity generation in EU countries, the report found. It’s also the reason why coal power declined 20% last year, making up only 13% of electricity generated in Europe.

“Rapid growth in wind and solar has forced coal into decline, but this is just the beginning,” said Dave Jones, senior electricity analyst for Ember and lead author on the report, in a statement. “Europe is relying on wind and solar to ensure not only coal is phased out by 2030, but also to phase out gas generation, replace closing nuclear power plants, and to meet rising electricity demand from electric cars and heat pumps.”

Last year’s COVID-19 lockdown measures resulted in less demand for electricity across the globe. European demand decreased by 4% in 2020, according to the report, which said COVID trends had no effect on the growth of renewable energy sources. Since 2015, Europe’s electricity emissions recorded a historic decline, becoming 29% cleaner, the report noted.

The milestone follows commitments from EU leaders last month to cut greenhouse gas emissions by 55% from 1990 levels by 2030. In the United States, their counterparts (同身份的人) successfully developed renewable energy to overtake coal consumption in recent years. Last May, renewable energy sources were consumed more than coal for the first time since 1885.

“Post-pandemic economic recovery must not slow down climate action,” said Patrick Graichen, director of Agora Energiewende, in a statement. “We therefore need strong climate policies — such as in the Green Deal — to ensure steady progress.”

10 . Hello, everyone! I’ve just come back from a wonderful trip to Tibet. Snow-covered mountains disappear into clouds that seem almost close enough to touch. It was so beautiful there that     1     . The scenery was so impressive and the air was so fresh and clean. Watching animals move slowly across the green grass,     2     . Attracted by its fascinating scenery, more and more visitors have crowded into the place. In order to protect it,     3     . However, cans, paper and plastic bags are still being thrown away by many tour groups. That’s to say,     4     . I worry about the effect this will have on the local wildlife.     5     We should all think about this question. Only when we learn to exist in harmony with nature can live a peaceful life.
