3 . We usually divide a year into four seasons. However, in Traditional Chinese Medicine (TCM) theory, there are five seasons — spring, summer, late summer, fall, and winter. Each of the five has many features which guide us to change our habits to keep the balance between our body and the external environment.

Winter in TCM

The ancient Chinese believed that winter is the Yin “阴” season in nature.     1     So, winter is the time of year to reflect on health, save strength and regain energy, preparing ourselves for the start of new life in the spring. Different aspects of our lives like exercise, diet and emotions can influence our health and, therefore, our well-being in winter.

    2    

In TCM theory, winter is a season to feed ourselves both spiritually and physically. Activities in the season have a turn inwards. For example, we can do more writing, reading and other soul-nourishing (滋养灵魂的) activities. Although energetic exercise should be avoided, it’s important to keep our body healthy with gentle exercise, especially outdoor activities, in which we can get fresh air and sunlight. In addition, we should also go to bed earlier to save more energy.     3    

Foods for winter

The principle of harmony between what we eat and the season is based on hundreds of years of experience in TCM. It suggests that we embrace locally-grown and seasonable foods, which is the way nature intends us to eat. During the winter, there are many foods beneficial to us.     4     — pumpkins, potatoes, root vegetables, winter greens, carrots, cabbage, mushrooms, and pears. Besides, hot soup, whole grains and roasted nuts also offer nourishment to feed the body in cold winter months. But always remember, moderation in all things is important.

Moods in winter

According to TCM theory, stress, depression and unresolved anger can also weaken our immune system, allowing external factors to affect our body in winter.     5     Meditation (冥想) and breathing techniques are particularly helpful, especially in relieving stress. TCM also offers a variety of treatments such as massage (按摩) and herbal formulas to manage our moods.

4 . Wildlife biologist Purnima Devi Barman remembers the first time she ever saw the nest of a greater adjutant stork (秃鹳) in a tree near her grandmother’s home. Her grandmother would tell her stories about birds and animals under the tree. The love for the natural world developed in those years led Barman to devote her life to saving the endangered greater adjutant stork.

Known as the Hargila in Assam, the greater adjutant stork is the second-rarest stork in the world. Unlike pandas or lions, whose attractive appearances help gain widespread support for their protection, these tall, bald, clumsy birds meet with bias in conservation campaigns.

“Hargilas also bear a reputation of bringing bad luck,” says Barman. “What was the point of writing my paper on them if there was no way of actually saving these birds? I had to start with changing the misconception.”

Not one to shy away from a challenge, Barman put her PhD on hold and set to work. “I started engaging with the women in the village. In our experience, educating and securing the participation of women ensures that the learning passes on to the next generation,” Barman says.

Today, around 400 women have been trained to work on conserving this rare bird. The group’s activities include awareness-building in schools and plantation drives in which 45,000 trees were planted to support the stork’s future populations.

A key component allowing Barman to successfully integrate conservation efforts into the village cultural life was her idea of building related livelihoods. Weaving (纺织) is a long-standing craft in Assam, so Barman created a self-help group employing women to weave stork patterns on textiles. This innovative idea was highlighted at the UN Champion of the Earth Awards she won in 2022.

Currently the number of greater adjutant nests in Assam’s Kamrup district has grown from 28 in 2010 to more than 250. The once unlucky stork is now a symbol of community pride, its pictures appearing on bags, blankets and celebration decorations.

5 . Nzou is one of the quiet stars of the Rhino& Elephant Conservation(保护) Programme at Imire in Zimbabwe(津巴布韦). The oldest elephant in the protected area, Nzou is around 55 years old, and has been there since she was two years old.

It is said that elephants never forget, but this special animal seems to have forgotten she is an elephant，and now thinks of herself as one of the buffaloes(水牛).

Nzou was brought to the area in the 1970s, when she lost her parents. She was encouraged to stay with the elephants. But she was happy with the buffaloes and has lived with them ever since. They could understand each other. Their relationship is amazing but not easy. Buffalo leaders are usually male(雄性的). Over the 40+ years that Nzou has been the leader, she has killed 14 young male buffalo who challenged her.

Nzou has never lost her elephant's instinct(本能) for loyalty(忠诚). One day, one of her keepers was attacked by a young male buffalo. Nzou stood over him as he waited for help to arrive, protecting him against more attacks from the buffalo.

Nzou no longer communicates with the other elephants at Imire perhaps she has forgotten how and no longer understands what they are saying. She is happy with the buffalo, and as long as they don't step out of line, she is happy and pleased to be their leader.

6 . Boston Marathon runners in recent years may have seen a smiling furry face around the two-mile mark. It’s Spencer, the therapy (治疗) dog, who became known as an unofficial mascot (吉祥物) for the marathon, He’s shown up on the sidelines every year since 2015—rain or shine.

One particularly rainy marathon catapulted Spencer’s fame, In 2018, his owner, Richard Powers, decided to put a bright yellow rain coat on the dog, making him stand out even more than he usually does. Photos of Spencer, who holds a “Boston Strong” flag in his mouth, went viral, and he became an inspiration to runners and onlookers alike, During the marathon, some runners stop in their tracks to take selfies with the dog-the line sometimes growing to 20 runners long.

But in 2020, Spencer was diagnosed with a tumor (肿瘤). His owner was worried, but Spencer is a fighter. He got the care he needed and survived. In 2021, he was back on the course and it was really kind of a miracle and that really hit home to a lot of people.

Unfortunately, Spencer caught another tumor—this one cancerous—and Spencer began chemotherapy. Powers didn’t think his beloved dog would make it out to the marathon of 2022. “Miraculously, he’s still here with us and an even bigger miracle, he was strong enough to go to the marathon,” he said.

After recovering, Spencer was back to work—not just at the marathon—but as a therapy dog, alongside his companion, Penny, who is also a golden therapy dog. Powers takes his two therapy dogs around to schools, hospitals and senior living centers.

“He’s a gift to us and we’re very lucky to have him. He’s too good so we want to share him with as many people as we possibly can. He does make a difference,” Powers said.

7 . Humans have always been working Earth’s land, and they also have always been studying and hoping to work the land of Mars one day.

Planetary scientist Abhilash Ramachandran at the Lunar and Planetary Science Conference reported that Martian dirt may have all the necessary nutrients for growing rice, one of humankind’s most important foods. However, he emphasizes that the plant may need a bit of help to survive in perchlorate (高氯酸盐), a chemical that can be harmful to plants and has been detected on the surface of Mars.

Ramachandran says they want to send humans to Mars, but they cannot take everything there, especially food. He thinks it’s going to be expensive, but growing rice there would be ideal.

Ramachandran and his colleagues grew rice plants in a Martian soil simulant (模拟物). They also grew rice in pure potting mix as well as several mixtures of the potting mix and soil simulant. All pots were watered once or twice a day. The team found rice plants did grow in the artistic dirt of Mars. However, the plants developed slighter shoots and thinner roots than the plants that grew from the potting mix and hybrid soils. The researchers also tried growing rice in soil with added perchlorate. They sourced some rice varieties—modified to stand environmental stressors like drought—and grew them in Mars-like dirt with and without perchlorate. No rice plants grew in a concentration of 3 g of perchlorate per kilogram of soil. But when the concentration was just I g per kilogram, one of the rice varieties grew both a shoot and a root, while another managed to grow a root.

The findings are encouraging, suggesting that by changing to improve with one successful modified gene, humans might eventually be able to develop a rice cultivar suitable for Mars.

9 . Wildlife conservation is the practice of protecting plant and animal species and their habitats. As part of the world’s ecosystems, wildlife provides balance and stability to nature’s processes. Wildlife conservation is aimed to ensure the survival of these species and educate people on living sustainably with other species.

The number of people has grown to more than eight billion today, and it continues to rapidly grow. The economic growth endangers the habitats and existence of various types of wildlife around the world, particularly animals and plants that may be displaced for land development, or used for food or other human purposes. This threat is at top of the list and means natural resources are being consumed faster than ever by the billions of people on the planet. The introduction of invasive species from other parts of the world is another threat to wildlife. Other threats include climate change, pollution, fishing and hunting.

International organizations like the World Wildlife Fund, Conservation International, Wildlife Conservation Society and the United Nations work to support global animal and habitat conservation on many different fronts. They work with the government to establish and protect public lands, like national parks and wildlife protection areas. They help write legislation(法规), such as the Endangered Species Act(ESA)of 1973 in the United States, to protect various species. They work with law enforcement to charge those with wildlife crimes. They also promote biodiversity to support the growing human population while preserving existing species and habitats.

National Geographic Explorers, like conservation biologists Camille Coudrat and Titus Adhola, are working to slow the extinction of global species and protect global biodiversity and habitats. Environmental filmmakers and photographers, like Thomas P. Peschak, are essential to conservation efforts as well, documenting and bringing attention to endangered wildlife all over the world.
