2 . 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.

3 . A lot of people find it difficult to do exercise regularly, even though they know it’s good for their physical and mental (身心上的) health. Yet keeping on a workout routine doesn’t necessarily go to the gym or run around your neighborhood. Gardening is a great example of a popular hobby that can be used as a workout.
Nashville resident Tom Adkinson, 72, is on board with the idea of gardening to stay fit. He has three gardens, which he uses primarily to grow tomatoes, sweet banana peppers and okra. Like traditional exercise, Adkinson does a lot of preparation before gardening, and then he spends hours watering and weeding (除草) all three gardens, involving bending and stretching, which he compares to performing garden yoga.
“It is wise of Adkinson to do so. Even though gardening may not appear difficult, using the body in new ways can make you hurt if you don’t warm up beforehand,” said Zeller, who teaches at the Rutgers Cooperative Extension of Cape May County in New Jersey.
Working in your garden just two hours a week could improve your mood. And the communal gardening, which is done by a number of people as a group in communities and schools, provides social benefits that can reduce stress and help fight against loneliness and even dementia according to studies.
“With all these benefits, gardening for fitness will be a trend (趋势) in the coming year,” announced Mandal, CEO of the fitness coaching app Future, “Our users at Future have already been asking their coaches to add gardening and landscaping activities into their routines because it’s easy to get and fit into their lifestyle.”

4 . The dry land in Gir National Park and Wildlife Preserve, located near India western tip, is the proud — and only — home of the Asiatic lion. By the early 1900s, however, their populations had decreased for homo loss and hunting, leaving fewer than 50 known individuals alive. Though their numbers have risen over the past several decades — climbing to around 670 in 2020, a successful story — the lions are still considered endangered.
One of the biggest challenges to keep the lions’ future is to track them, a hard work. Some animals, like tigers and zebras, have special coat patterns (图案) that provide useful marks to the researchers. But for the Asiatic lions, researchers must look elsewhere.
In 2019, Banerjee, who worked for Indias National Tiger Conservation Authority, developed an AI system to recognize the lions with high accuracy (精准). The AI program, SIMBA, has been applied in practice. “It will be a fantastic tool for long-term lion monitoring,” says Banerjee. He adds, “It could help forest officials arrive at a more accurate estimate (评估) of Gir’s lion population. In a few years, the group will have a rich collection of information — how many lions are male, female, how many will bear babies and how many are dead.”
Despite the advantages, Baneijee also adds his worries. He suggests certain rules be made to prevent main information from being stolen. “Where tools like SIMBA really shine”, he says, “is in helping researchers develop monitoring plans that are keys to the protection of at-risk animals,” he says, “otherwise, all your efforts will be in vain.”

5 . The Australian sand octopus (章鱼) was discovered in 1990 and is the only octopus species known to bury itself deep in the sand to hide from enemies. A team of researchers are studying the venom (毒液) of this kind of octopus. They have discovered that the venom may greatly slow cancer growth. And it can also help fight drug resistance in patients with a BRAF-changed skin cancer. BRAF is involved in managing cell growth. A change in it results in abnormal cell growth. These BRAF changes are seen in half of all cases of skin cancers.
“We and other groups have previously discovered that other animals-snakes, spiders, bees-have anticancer properties,” said Dr. Maria, the study’s lead author. “However, in my current knowledge, the anticancer properties of an octopus species have never been studied or confirmed before.”
Current treatments face a few challenges including low response rates, poisoning and side effects, as well as drug resistance. The octopus venom slows the growth of BRAF-changed skin cancer. More importantly, it is safe to be used in large quantities — it is not poisonous. Therefore, in combination with other drugs, the treatments could potentially achieve better and safer patient outcomes.
It is very unlikely that the octopus has specifically developed its venom to contain an anticancer substance. According to the researching team, the octopus venom contains over 1,000 unique substances with several functions such as reducing pain and anticancer.
“In this study, we have shown that the octopus venom specifically targets BRAF-changed skin cancer. The next step is to examine whether similar promising results are applicable for other BRAF-changed cancers.” said Dr. Maria. “Before it can be used on patients, the team will need to perform several rounds of lab testing and clinical trials to understand how it works and its full potential as a drug against skin cancer.”

6 . It’s reported that about 20 percent of the Amazon rainforest has disappeared during the past 50 years. Deforestation is not only threatening the millions of unique plant and animal species native to the Amazon River area, it’s affecting humans worldwide. When it comes to the protection of the Amazon, it’s hard for many people to relate because they don’t feel connected to the area. There are actually a lot of direct connections, no matter how far away we are.
A connection that affects everyone on the planet is climate (气候) change. Planting new trees in the forest is basically a way of removing CO2 from the air. Rain forests have a carbon (碳) reduction nearly equal to half of what is in the air. About half of that is in the Amazon. Another case in point is a big snake called the bushmaster that lives in the Amazon. Today, millions of people use medicines made from its venom (毒液) to treat high blood pressure. So they have longer, fuller, and more productive lives.
In the 1960s, there was only one highway in the entire Amazon. That’s an area as large as the continental United States with one highway and three million people. Today, there are between 30 million to 40 million people, countless roads, and about 20 percent forests have been cut down. But on the plus side, 50 years ago there were only two national parks and a national forest and a reserve in Brazil. Today, more than 50 percent of the Amazon is under some form of protection.
“There’s been a lot of damage done and forest lost, but nothing is gone until it’s gone”, noted National Geographic explorer Dr. Thomas Lovejoy. “We want to see more shared planning between the departments of transportation, energy, agriculture, and the other industries in the area. We think Amazon cities can have higher quality of life and keep people in existing cities so there’s less reason to deforest.”

8 . Hummingbirds (蜂鸟) are a very important part of Mexico’s ecosystem, but because of the ever-spreading city landscape, they face all sorts of serious dangers. That’s where 73-year-old Catia Lattouf de Arida comes in. As a self-taught hummingbird care-taker, she devotes most of her free time and resources to nursing the tiny birds back to health. Her home in Mexico City has become known as a hummingbird hospital
Catia’s story as a hummingbird nurse began in 2011, at a very dificult moment in her life. At that time, she focused on her battle with cancer and fell into a depression (抑郁) . She was walking on the strect one day when she noticed a hummingbird that had suffered a serious eye injury. The kindhearted woman took it home and named it Gucci. She managed to nurse Gucci back to health, but she said it was Gucci that saved her. Why? Because the hummingbird managed to pull her out of the sadness and loneliness that had taken over her life.
Word of her success spread among Catia’s friends, and before long some of them began bringing her injured hummingbirds. She didn’t repulse them at all. She began to study the bird and their habits in order to better take care of them, and after 11 years of experience, the 73-year-old woman is considered an expert on hummingbirds.
In order to raise awareness of the difficult situation of hummingbirds in Mexico, Catia Lattouf de Arida started posting videos of the patients in her Mexico City apartment on social media, and many of them became popular. That’s when the need for her nursing services really blew up. She has cared for hundreds of hummingbirds in her 11-year career, when she has had as many as 50 of them in her apartment at any one time. She spends pretty much all her time looking after the tiny birds.

10 . Whenever I order food for delivery, I play a little game to guess how many sets of tableware(餐具)the restaurant will provide with my meal. Sometimes restaurants will throw in two, three or four sets for just one order. But I rarely need any tableware at all, and the waste goes into the trash or collects dust in a kitchen drawer.
Researchers working with Chinese technology group Alibaba tried a simple approach to this problem. Instead of just wastefully doling out tableware, the company required food-delivery customers in some cities in China to pick how many sets of tableware they wanted to receive.The default (默认设置)was set at zero. The result, published today in the journal Science, was a 638% increase in the share of no-tableware orders. If applied across China, researchers found, the approach would save nearly 22 billion sets of plastic tableware. The study doesn’t cover carbon emissions, but it’s safe to say that the impact would be significant. It struck me as a useful reminder of the many low-hanging fruits across the economy that can cut waste, and emissions.
Nudging its customers cost Alibaba nothing more than a few hours of software engineering time and the impact it brought was immense. The concept of nudging comes from the field of behavioral economics known as nudge theory. It suggests that a slight action can encourage good human behavior without the need for policies that limit choice or economic punishment that raises the cost of bad behavior. To nudge customers to eat better, for example, a restaurant might organize its menu by listing healthy options first and bury unhealthy ones at the bottom. More recently, some big companies like Google have also begun to use nudges to advance climate objectives.
Behavioral economics broadly, and nudges more specifically, aren’t without controversy. Some might think it assigns consumers responsibility for addressing environmental challenges. But there is another way to look at it. In the absence of necessary policy—and policy is needed一companies can help encourage a widespread shift of consumer behavior.
And all of that behavioral change can add up. The International Energy Agency found in 2021 that small behavioral changes in energy consumption such as walking instead of driving and adjusting the thermostat could in total shave off 4% of global emissions. The more that companies can do to facilitate such changes, the better.
