1 . Finding a California condor in the wild would be the most unusual treat. perhaps even more unusual than finding a wolf in Yellowstone National Park. In fact, the wolf was what opened my eyes to the fact that humans could bring an animal back to the place where it had disappeared.
In 1987, there were only 27 California condors left, none of which were in the wild, only in captive breeding programs, It was those breeding programs that contributed to their population rise, enough that by 1991 some of them could be freed into the wild.
Still, the hope of seeing a California condor, which remains an endangered species, is very low, let alone getting a photo of one. California condor population dropped mostly due to human factors, such as poaching and living areas destruction-these are challenges California condors still face today.
Although this is just a bird’s-eye view of the challenges California condors face and there are many others, it is part of why the opportunity to work with the US Fish and Wildlife Service team and their partners helping their recovery is so special to me as a photographer. I am not only able to photograph the birds in their wild living areas, but also understand and record how difficult the work is of those people on the front lines of the protection.
I am grateful for the work of the team, and my hope is that California condor population will continue to rise allowing future generations an opportunity I never had when I first got here-to look to the sky and see one flying around.

2 . Landscape architect Kotchakorn Voraakhom has designed a new green roof on the Rangsit Campus of Thammasat University, about 25 miles north of central Bangkok, Thailand. Her imaginative work challenges the common thinking that urbanization has a negative impact on the planet, whether flooding, excess (过度的) energy use, disrupted (扰乱) biodiversity or the heat island effect.
The 236, 806-square-foot structure, which opened in December 2019, includes a flood water management system and Asia’s largest rooftop organic farm. It combines modern landscape architecture with traditional agricultural knowledge, creating a green and friendly environment.
The green roof, containing an H-shaped landscape, looks like a futuristic hill with a brick building beneath it. The hill features a complex pattern of zigzagging terraces (之字形梯田) of planted beds, leading all the way down to the bottom. When rainwater hits the roof, it flows down the zigzags while being absorbed by the soil in the beds, The excess water is directed into four storage ponds — with a capacity of up to 3 million gallons. The process slows down the flow speed of rainwater runoff compared to a normal concrete rooftop. This keeps the area from flooding during heavy rains.
The roof’s terraces are filled with organically grown crops, including a drought tolerant variety of rice, many local vegetables and herbs. The farm can supply the canteens on campus with a large amount of rice, herbs and vegetables a year. The food waste is composted (把……制成堆肥) to fertilize the farm, and water from the storage ponds is used to water plants, creating an entirely localized and circular system.
The farm serves as an outdoor classroom and a source of local jobs, too. Farmers offer workshops on sustainable agriculture and nutrition as part of the university’s sustainability curriculum. “Students and community members are invited to participate in seasonal seeding, harvesting, and so on,” says Voraakhom. “The urban farm is training a new generation of organic farmers with real-world skills. It also promotes a sense of community.”

4 . Every year, about 25, 000 plastic tents are thrown away after festivals in the Netherlands. That’s enough tents to get you from base camp to the top of Everest (珠穆朗玛) if you set up a tent every metre of the way. These plastic tent not only cause a lot of pollution to the environment, but they also have to be dealt with.
Into this situation stepped the KarTent. It’s a good solution to the plastic tent problem. The KarTent is a cardboard (纸板) tent. It is put up for you at the beginning of the festival and when the festival is over, the makers pick it up, take it away and recycle it into other products. No more plastic, no more waste. The production of one KarTent produces half the CO2 of a plastic tent. In the past, about thirty different materials were used to produce a tent. It may take hundreds of years to biodegrade (降解) the materials. However, to produce a KarTent, only one material is needed. It’s cardboard.
The tent is the brainchild of three Dutch businessmen: Jan Portheine, Wout Kommer, and Timo Krenn. After working on a cardboard beach hut, architect Jan started to look for other ways to use the skills he had learned, “In a meeting I met Wout and we found pictures of tents being left behind at festivals, and that’s how the idea started.”
Perhaps next time you’re at a festival you won’t have to look out across the sea of plastic, instead you’ll see the cardboard tents being neatly put into a truck and taken away to be recycled.

6 . The world’s forests may hold more secrets than previously thought: a new global estimate of tree biodiversity suggests that there are about 9,200 tree species remaining undocumented. Most are likely in the tropics, according to the new research.
The new research drew on the efforts of hundreds of contributors, who have categorized trees in two huge data sets: One, the Global Forest Biodiversity Initiative, records every species found in extensively documented forest plots worldwide. The other, TREECHANGE, puts together sightings of individual species. Together they suggest there are approximately 64,100 recorded tree species on the planet — up from previous estimates of around 60,000.
The researchers reached their estimate of an additional 9,200 yet undocumented species on the basis of the number of rare ones already in the databases. Most unknown species are likely to be defined as rare, found in limited numbers in small geographical areas, says the quantitative forest ecologist Jingjing Liang. The team’s result is “a rather conservative estimate,” Liang says, “because scientists know less about the preponderance of uncommon trees in places such as the Amazon, where out-of-the-way spots could host pockets of unusual species found nowhere else.” “If we can focus the resources on those rain forests in the Amazon,” Liang adds, “then we would be able to estimate it with higher confidence.”
Silman, a conservation biologist, who was not involved in the new study agrees that the study result is likely an underestimate. His and his colleagues’ local surveys suggest there are at least 3,000 and possibly more than 6,000 unknown tree species in the Amazon basin alone. Tree species often get grouped together based on appearance, he notes, so new genetic analysis techniques will likely lead to the discovery of even more biodiversity. Sliman wonders how many species will go extinct before scientists describe them. “How many are already known to native peoples in the Amazon — or were known to peoples or cultures who have themselves been made extinct through colonization, disease, or absorption? How many “species” already have dried samples sitting in a cabinet?” he says.
Searching for the new species will inform not only conservation but the basic evolutionary science of how and why species diversify and die out, Silman says. “Just the fact that there are thousands of species of something as common as trees out there that are still left to be discovered,” he adds, “I find pretty inspirational.”

7 . The most powerful earthquake in the past 40 years caused a tsunami that crashed into coastlines across Asia yesterday, killing more than 6,500 people in Indonesia, India, Thailand, Malaysia, and at least four other countries. Fishermen, tourists, hotels, homes, and cars were swept away by huge waves caused by the strong earthquake that reached a magnitude of 9.0. The undersea quake struck around 7:00 a.m., Sunday off the west coast of Indonesia’s Sumatra Island.
In Sri Lanka. some 1,600 kilometres west of the quake centre, the number of deaths stood at 2,498, and one million more were affected by the tsunami, government officials said. Indian officials said as many as 1,900 had been killed along the southern coast. Another 254 were found dead in Thailand and 54 in three other countries. In southern Thailand, 1,900 people were hurt and many more were missing, local officials said. Foreign aid is being organised for the tsunami-hit countries. However, dangerous conditions and damaged roads will make it difficult to deliver food and supplies.

When I was a child, I hoped to live in the city. I think I would be happy there. Now I am living in a city, but I miss my home in countryside. There the air is clean or the mountains are green. Unfortunately, on the development of industrialization, the environment has been polluted. Lots of studies have been shown that global warming has already become a very seriously problem. The airs we breathe in is getting dirty and dirtier. Much rare animals are dying out. We must find ways to protect your environment. If we fail to do so, we’ll live to regret it.
9 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.
As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.
