3 . A new study by the Zoological Society of London has found that nearly one in five of the world’s 10,000 species of reptiles (爬行动物) are threatened with extinction. The study, which has been printed in the journal Biological Conservation, was carried out by more than 200 experts who assessed the risk of extinction of 1,500 reptiles selected at random from around the globe.
The primary author of the paper, Monika Bohm, explained to the Zoological Society:” Reptiles are often associated with extreme habitats and tough environmental conditions, so it is easy to assume that they will be fine in our changing world. “However, that’s far from the truth:” Many species are very high specialized in terms of habitat use and the climatic conditions they require for day to day functioning, “Bohm said.” This makes them particularly sensitive to environmental changes. “The paper highlights three critically endangered species in its research, including the jungle runner lizard Ameiva vittata, which has only ever been spotted in the Cochabamba region of the Bolivian jungle—an area under threat from the growth of agriculture and logging. The two most recent searches for the species have been unsuccessful. Meanwhile in Haiti, six of the nine species of Anolis lizard in the country risk extinction due to increasing deforestation (毁林).
Also at risk are freshwater turtles, with 50% of all species at risk of extinction from hunting; turtle parts are in high demand as ingredients in traditional medicine. According to the study 30% of freshwater reptile species are also in danger of completely disappearing.
Reptiles have a long evolutionary history: snakes, lizards, crocodiles and tuataras first appeared on earth around 300 million years ago. They are an important part of many ecosystems. ”This is a very important step towards assessing the conservation status of reptiles globally, “Philip Bowles from the IUCN Species Survival Commission said in response to the study.” Tackling the identified habitat loss is key conservation priorities in order to transfer declines in these reptiles.”

4 . In winter, intense cold in China’s Jilin Province can turn tripping water into ice within seconds. Yet, 63-year-old Ren Jianguo gets up early every day to spread corn on the riverbank to make sure thousands of migratory birds(候鸟) have food to go through the cold days.
Ren lives in Jilin City which is built on the banks of the Songhuajiang River. Over the past 26 years, he has been one of the many volunteers protecting migratory birds on the river’s Changbai Island. Local residents label him as “Uncle Bird”. Winter is the busiest time for Uncle Bird as it is the season when large amounts of migratory birds fly here to avoid the biting cold days in Siberia, Russia.
On the upper reaches of the Songhuajiang River is Northeast China’s largest artificial lake. The temperature of the water stays at around 4-10℃ all year round. This allows Changhai Island to welcome countless migratory birds.
“As long as they choose to stay in this city, there should be people to take care of them. When it becomes difficult to find food in winter, I call for donations or sometimes pay for the food myself to secure their survival during the winter,” Ren said.
Jilin City, which is part of the migratory passage of birds in East Asia, is one of the few warm wetlands in northern China suitable for migratory birds to rest. To improve the environment here, the Chinese government has invested about 26.6 billion yuan for water pollution control and prevention along the Songhuajiang River since 2006.
For Ren, a small house near the riverbank has almost become his “second home”, a place from which he can patrol(巡逻) along the banks, observe birds, educate the public about bird conservation and, after a long day of work, light a fire and enjoy a warm meal.
“I simply want this to be a warm and welcoming place for birds when they choose to stay here for a temporary rest,” he said.

5 . When Simon Cane was in the second grade, he began learning about all the ways humans have an impact on the environment and really took those classroom lessons to heart in a way that set him apart from his schoolmates at his elementary school, P. S. 81, in the Bronx. “He told me we drove too much and made too much pollution,” his dad, Jonathan Cane, told Runner’s World. So Simon convinced his parents to start hanging their clothes to dry, taking the stairs instead of elevators, and other “green” measures.
“For much of kindergarten and first grade I rode my bike to Simon’s school with him on the back,” Jonathan said. “We had a lot of fun being outdoors. We’d stop to give our dog treats and generally enjoyed it.” As Simon got bigger, though, it wasn’t practical for him to ride on his father’s back, but it also didn’t make sense to ride together — both because of safety concerns and because there was no place to put away Simon’s bike. So, most of the time they drove the 1. 5 miles to school.
But in 2019, when Simon was going into third grade, the 8-year-old came up with a new way to help the planet: running the 1. 5 miles to P. S. 81. And Jonathan promised his son he’d join him for as long as he wanted.
“We did a test run one day in August, and decided to give it a go. To be honest, I thought he’d blink (眨眼)after it got really cold or rainy, but he never did,” Jonathan said. He recalled one day when the weather was particularly bad. “It’s really raining out there today,” he told Simon. “And Simon said, ‘Well then we’re going to get wet!’ He took pride in toughing it out, and it became a really fun family routine.”
Since the start, Simon has run with his dad and their black dog, Lola, and has even inspired his mom, Nicole Sin Quee, to join in. They soon became known as “the family that runs to school”.

7 . In July 2017, Hoh Xil became a world heritage (遗产) site and there live more than 70, 000 Tibetanantelopes. Every year, pregnant (怀孕的) Tibetan antelopes migrate (迁徙) to Hoh Xil between the end of May and early June to give birth and leave with their children around August. Zonag Lake at the heart of Hoh Xil is known as the “delivery room” for the species.
About 40 female Tibetan antelopes with three young were spotted crossing the Qinghai-Tibet Railway Saturday. Experts say that in recent years, the number of young Tibetan antelopes among the migrating groups consisted of between a fifth and quarter of the population.
“In the early stage of migration, Tibetan antelopes face a high risk of falling prey to predators (盗猎者) so the number of young Tibetan antelopes is relatively small, and there may even be none,” said Lian Xinming, an associate research fellow at Northwest Institute of Plateau Biology, Chinese Academy of Sciences.
According to research, the number of Tibetan antelopes that migrate back has been rising. A total of 5, 952 Tibetan antelopes were spotted migrating in 2020, and 233 more in 2021. “This year’s migration season is expected to finish in early September. The population is expected to continue to increase,” Lian said.
Tibetan antelopes are mostly found in Tibet autonomous region, Qinghai province, and Xinjiang Uygur autonomous region. The species is under first-class state protection in China.
In the 1980s, the Tibetan antelope population declined sharply from 200, 000 to 20. 000, due to illegal hunting. It has recovered thanks to the country’s efforts to improve its habitat and crack down on poaching (盗猎).
To make sure the species go back to their habitats safe and sound, the reserve’s management bureau has staff monitor their migration. When they come over in large groups, they temporarily close some sections of the road to make way for the animals and prevent them from having interactions with humans.

8 . Climate Acts Must Focus on Youth
Children and young people are bearing the burden of climate change. However, they are consistently overlooked in the design and content of climate policies and related measures. The rights of the youth need to be put in a central place in a country’s climate change plan as extreme weather events are threatening their lives and destroying the infrastructure critical to their well-being.
The scientific community has sounded the alarm that climate change is a global emergency, and the risks of deadly drought, frequent floods, heat waves, extreme weather, and poverty will significantly worsen.
Over half a billion children live in high flood zones and nearly 160 million live in areas of extremely high drought, said a report released in 2015 by the United Nations Children’s Fund, or UNICEF. Polluted air has a huge impact on children’s brain development. It is estimated about 2 billion children live in areas with air quality that is well above international pollution standards. Air pollution, lack of safe water, undernutrition is strongly linked to pneumonia, a leading cause of death among children, killing nearly 2, 400 children a day. The increase of diseases such as malaria and dengue fever has the greatest impacts on children, for example, 90 percent of the disease burden that is attributable to climate change is born by children under the age of five. The UNICEF report said all these challenges are exacerbated by climate change.
Through the intergovernmental cooperation on climate change, the UN has made it clear the impacts of climate change are global in scope and unprecedented in raising. Actively responding to climate change is not only imperative, but also key to sustainable development for generations to come as children and young people are the future of mankind.
We are all glad to see children and young people are encouraged to play a key role in addressing climate-related risks by promoting environmentally sustainable lifestyles and setting an example for their communities.
