For generations, Babusha,     1     is on the southern edge of the Tengger Desert, was troubled by sandstorms that frequently buried farmland, often leaving nothing to harvest.

Today, the desert’s southward spread has been stopped thanks to a green belt ten kilometers in     2     (long) and eight kilometers in width,     3     (plant) by Guo Wangang and his colleagues.

Guo’s father was one of the six men who first began planting trees in Babusha     4     (prevent) their land from being buried in 1981. When he     5     (force) to stop in 1983 due to poor health, Guo quit his job in the city and followed in his father’s rootsteps because he didn’t want to see the trees die. A deadly sandstorm in 1993 which claimed 23 students’     6     (life) firmed his resolve, turning Guo into     7     stubborn soldier, unwilling to give up the fight. “I asked     8     (I) that if we couldn’t protect our farmland or our children, how were we supposed to keep going?” Guo recalled. “That’s when I made up my mind to devote my life to this fight.”

Year after year, Guo and his colleagues have continued to plant trees each spring and fall,     9     (watch) out for fire and pruning (修剪) them in the winter. The vegetation coverage rate in Babusha has increased     10     less than 3 percent to 70 percent and the desert no longer moves further south.

4 . A new form of real estate(不动产)is appearing along the beaches of South Africa and on the dry islands off its coast-tiny white beach huts. With good ventilation and a sea view, they are just big enough to fit a family of African penguins. Their unique selling point: a safe and cool place for penguins to breed.

African penguins, unlike their relatives that live in snow and ice, live well in the cold currents of the South Atlantic Ocean. But when they come to land, their thick black coat absorbs the heat, and they desperately look for cover-both for themselves and their fragile eggs.

Historically, the penguins dug burrows in layers of guano-accumulated seabird and bat feces- that lined Africa’s penguin colonies, but in the 19th century, traders started selling guano(鸟粪)as fertilizer, leaving the penguins and their eggs increasingly exposed to predators and the baking sun. This, combined with other threats such as egg poaching, overfishing and climate change, has caused African penguin populations to plummet. In 2019, they were thought to be less than 20,000 breeding pairs, down from an estimated 1.5 to 3 million birds in 1900.For more than a decade, the species has been listed as endangered by the IUCN.

To date, the African Penguin Nest Project has installed more than 1,500 nests across five of South Africa’s penguin colonies, and plans to expand into Namibia next year, the only other country with breeding populations of the species.

“This is still just a drop in the bucket,” says Graham, who anticipates they will need to deploy at least 4,500 more ceramic homes to protect penguins currently nesting in exposed areas. “The goal is that every penguin that needs a nest will get one.”

7 . In the northernmost edge of Colombia sits the coastal town of Acandí. Access to the town is only by water or air; there is no road that leads there. The residents there are faced with the struggles of balancing livelihoods while protecting biodiversity.

In the past, traditional community fishing methods, passed down by the elders, focused on the reasonable fishing and management of resources. However, the introduction of large-scale trawling vessels(拖网渔船) decades ago gradually depleted the area’s fishing resources, leading to damage to marine(海洋的) life seriously.

Jesús Antonio Julio Cuestas, who serves in the region’s conservation and management of marine resources, stresses the bad impact of these developments and calls for new fishing techniques. “Fishing and conservation co-exist as long as we have good management practices and reasonable use of our fishing resources,” says Cuestas. He and other officials actively monitor fishing activities in Acandí. Each morning, they visit the fish markets to gather data on fishery resources—including prices and sizes—to monitor the state of the local fishing industry.

Along with Cuestas, the fishers work to reduce their impact on the marine ecosystem. By changing fishing methods and adopting new practices, they aim for a more balanced approach to fishing. “This year the local fishermen have not used the trawl net s that were causing the death of the leatherback sea turtles,” explains Cuestas proudly. Changes include the efforts of boats to protect the seagrass that serves as feeding grounds for marine life and an end to fishers throwing net s where turtles lay their eggs.

This marine reserve in Acandí, Cuestas believes, is their greatest treasure. He attaches great importance to working together with local residents to improve the quality of life while preserving the marine ecosystem. By doing so, he imagines a picture where individuals from the fishing community can pursue various careers, such as engineers or lawyers, proudly stating that they are the products of the fishing tradition in Acandí.

8 . Have you ever wondered what happens to your mobile phones and laptops after you throw them out to make way for a newer model? According to its latest Global E-Waste Monitor, India is the third top producer of e-waste in the world. E-waste in Indian landfill goes on to pollute soil and groundwater, affecting food supply systems and water sources.

Thankfully, the country has a new group of artists who are changing these thrown mechanical items-from mobile phones to old televisions- into large murals (壁画) and artworks to creatively show their concern for the waste problem.

Over the past quarter of a century, Mumbai’s Haribaabu Naatesan has transformed hundreds of tonnes of e-waste into art, integrating elements from nature and industry. “I get my waste material from friends, relatives and neighbours who know my interest in e-art and send me bags of thrown electronic appliances,” says Naatesan. Over his career, he has created huge murals for several companies. He has also showed his work at the India Art Fair, as well as several other national displays.

Another artist Vishwanath Davangere has also long worked with e-waste. He likes to take apart old laptops and reassemble (重新组装) them into birds, animals and plants. After retirement, he started pursuing this hobby more seriously and started selling his creations across the world. His most outstanding works include a robotic Egyptian statue with glowing red eyes and a Milky Way made from keyboard keys. He hopes to enable others to reconsider their own consumption habits and make more environmentally conscious choices.

“By giving e-waste a second chance, I aim to raise awareness about the environmental impact of electronic waste.” says Davangare, who today has a collection of more than 600 eco-art objects.

9 . The world’s coral reefs do more for the planet than provide underwater beauty. They protect shorelines from the effects of hurricanes. An estimated 500 million people earn their livelihood from the fishing stocks and tourism opportunities reefs provide. The tiny animals that give rise to reefs are even offering hope for new drugs to treat cancer and other diseases.

Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world. So now scientists around the world are looking for all kinds of ways to protect and maybe even revive(复苏) corals. In the Bahamas, Ross Cunning, a research biologist at Chicago’s Shedd Aquarium, is focusing on corals with genes that could make them natural candidates for restoration projects. He recently published a study of two Bahamian reefs, one that seemed to survive an intense 2015 heat wave, and one that didn’t.“It sets the stage to find out which genes are responsible for thermal tolerance,” says Cunning, adding that he hopes discovering those genes will help scientists one day breed more heat-tolerant coral.

In Massachusetts, Cohen’s research has found two key elements that seem to protect corals. The first: internal(内部的) waves beneath the ocean’s surface that bring cooler currents to heat-struck corals, essentially air-conditioning them as temperatures rise. The second: adaptation, a quality that corals found in Palau’s warm lagoons(环礁湖) seem to display.On average, these lagoons submerge(淹没) coral in water that is two degrees Celsius warmer than the water outside the lagoons. “We think the fact that they can deal with these higher temperatures is built into their genetics and allows them to deal with the heat waves.”

She’s also found evidence of corals evolving more quickly in the past two decades to withstand rapidly warming temperatures. The big question scientists are now enquiring into, says Cohen, is whether there’s a cap on how much more heat corals can adapt to. Cohen calls these regions with heat-adapted corals as “super reefs,” and like Friendlander, advocates for using marine reserves to protect them.

10 . New Zealand plans to put a price on sheep and cow burps (打嗝) to reduce greenhouse gas emissions (排放). If the plan is passed, New Zealand will become the first country to tax (征税) farmers on each burp of their cattle, since the burps give out methane (甲烷) into the atmosphere.

“There is no question that we need to cut the amount of methane we are putting into the atmosphere, and an effective emissions pricing system for agriculture will play a key part in how we achieve that,” Climate Change Minister James Shaw said.

Animal agriculture is one of the leading causes of global warming. It is reportedly responsible for at least 14.5% of the world’s emissions. Moreover, cows are by far the biggest contributors. This is so because they produce 40% of global methane when they burp, fart (放屁) and produce waste. Also, methane is 80 times more warming than CO₂ although it’s shorter-lived in the atmosphere.

New Zealand, which has a population of five million people, has around 10 million cattle and 26 million sheep. “Almost half the country’s total greenhouse gas emissions come from agriculture, mainly methane,” the draft plan explained.

The “burp tax” is expected to take effect in 2025. Mr. Shaw wants farming to be more environmentally friendly. He also wants farmers to change the way they farm. He wants them to feed their animals on seaweed instead of grass. This will produce fewer emissions. Mr. Shaw also said farmers can reduce the tax they pay by planting more trees. Another suggestion is for cows to wear special masks.

New Zealand’s farmers support the government. They want to do their bit to help the environment.
