1 . The ocean depths contain the metals needed for the widespread use of battery-dependent technologies like electric vehicles, which will help reduce greenhouse gas emissions. Interested parties see this as a solution to our technological demands and the pressing need for a “green transition”. However, it raises a crucial question: should we mine the deepest stretches of the world’s oceans?
Some scientists and activists warn that seabed mining could cause an irreversible (不可逆的) chain reaction, severely harming the ocean and threatening entire ecosystems on the ocean floor. There are also potential risks to our health, including toxic metals entering the human food chain, and affecting climate change. The most significant direct impact of mining in remote ecosystems is the probable loss of habitat and biodiversity.
Dr Chong Chen is a deep sea biologist at the Japan Agency for Marine-Earth Science and Technology (JAMSTEC). “There are undoubtedly many undiscovered species with abilities and functions that we cannot even imagine exist,” he says, “and we could lose them without knowing they ever existed.”
The mining process also disturbs seabed sediments (沉积物) and releases them back into the sea, raising additional concerns among scientists. Mining is for metals, whose stability of the construction are unchecked. “Some of those may be broken down and be directly into the water column,” says Jeffrey Drazen, professor of Oceanography with the University of Hawaii at Manoa. “Some of these metals are toxic to life.” says Professor Drazen. At the same time, he acknowledges the core challenge is ensuring whether the benefits of extracting (提取) deep-sea mineral resources outweigh the potential harm to our ecosystem. He notes that it’s a tough choice.
The positive development is that, for the first time, companies, governments, and civil society are actively participating in international discussions to create rules and regulations for the deep-sea mining industry before it begins.

3 . Thanks to the 1999 Environment Protection and Biodiversity Conservation Act, 26 endangered species in Australia have seen their populations recover.
It seems like that we're always hearing about new animals that have become endangered, but there's some good news in Australia: 26 animal species no longer meet the criteria to be listed as threatened. Australia’s biodiversity has been in decline, with more than 1, 700 species and ecological communities known to be on the line. In 1999, the Environment Protection and Biodiversity Conservation (EPBC) Act was passed to introduce protections for endangered animals. The burrowing bettong is one of 26 Australian species that have returned from the edge of extinction.
Seemingly these are working, as a recent study published in the journal Biological Conservation reviewed the animals that were previously or currently listed as threatened between 2000 and December 2022, and discovered that 26 species had recovered to no longer meet the criteria. Species that have seen improvement include the charmingly named burrowing bettong, the golden bandicoot and the bulloo grey grasswren.
Factors behind this improvement include habitat management, control of introduced predators (捕食者) and translocation of endangered animals to predator-free islands. However, the species have not been officially delisted at this time. The EPBC Act only allows species to be delisted if doing so will not have a negative effect on their survival, and researchers believe that conservation gains could be lost should management efforts be stopped.
Dr Michelle Ward, a conservation scientist at WWF Australia, told The Guardian, “The key problem with delisting species is that then they no longer have monitoring and no longer need certain funding plans.”
However, it is promising that researchers have found signs of improvement. Hopefully this will continue among these and other species!

4 . The maleo (塚雉), a bird with black feathers and a pink chest, is native to Indonesia’s Sulawesi island and a few neighboring ones. The International Union for Conservation of Nature (IUCN), which identifies wildlife across the world currently facing threats, estimates only 800 to 1,400 adult maleos remain in the wild. Experts do not know how many maleos still live across West Sulawesi island. They were only able to record the presence of nesting grounds in 23 villages based on reports from locals in the area. But of those, only 18 are considered active nesting areas.
Recently, the birds have been faced with new threats, which accelerate their decline. The Indonesian government plans to move the nation’s capital from Jakarta to a new city on Borneo island, which is just a six-hour boat trip apart from Sulawesi island. The island takes on the building of new roads and seaports to be used to transport materials to the new capital. Activities also include tree clearing, digging, and removing stones. The process already has changed the forest environment on West Sulawesi and is harming maleo nesting areas near the beach. These changes have made the trip for maleos to lay their eggs increasingly difficult.
Another problem has been poachers. The Associated Press reports that, regardless of official ban, they steal maleo eggs that the males’ parents have hidden in the sand, and sell the eggs for about $1 to people as food. The eggs are a traditional gift for many people in Mamuju and other parts of Sulawesi.
“As far as I know, maleo birds are in decline,” said Andi Aco Takdir, chief of the West Sulawesi Forestry Agency. He pointed to several reasons for the decline, including destruction of beach areas, and expanding human development activities. He added that government officials there are prepared to take steps to protect the maleos even with the new capital development. Andi said, “Nature conservation must be used as an achievement and must not be built leaving behind problems.”

5 . Humans can make do with scarves, coats and gloves in cold weather. Some animals can hibernate (冬眠) for the winter. A new study finds that reptiles (爬行动物) and birds do something that is similar to hibernation, but a little different. In very cold weather, their body temperatures greatly drop into an energy-saving state in order to survive. The ability to thermoregulation (体温调节) for reptiles and birds is possible.
In Texas, where the city of Beaumont reached a low of 18 degrees Fahrenheit last month, it looked as if alligators (短吻鳄) had died of cold — yet alive in iced-over water. By ensuring their long noses stayed above the water line, the cold-blooded creatures were able to lower their body temperatures to survive the sudden short period of very cold weather. The process, in the case of cold-blooded animals like reptiles, is called brumation — it’s like a short state of hibernating. While in this state, reptiles become sleepy and they can go for a long time without eating or drinking. For example, alligators can be in brumation from just a few hours to months.
Like reptiles and mammals, birds can go into a state called torpor in order to save energy under very cold conditions. “Torpor is somewhere between a short sleep and hibernation,” said Justin Baldwin, a PhD candidate in biology at Washington University in St. Louis. Baldwin studied 29 species of hummingbirds living in Colombia. Researchers found that hummingbirds can enter into deep or shallow torpor, depending on several factors, including their size and weather conditions. In deep torpor, the birds are much more likely to be affected by disease. And what’s more, they would be easily harmed by their enemies.
Some bird lovers want to help the birds when they are in torpor. For example, the Bird Alliance of Oregon offers a few tips on how to keep the birds from danger.

7 . Hotter, drier conditions over the past four decades have been decreasing the rainforest birds’ body size while lengthening their wings, a study published in the journal Science Advances said on Friday. “This maybe an adaptation to hotter temperatures. Even in the middle of the primitive Amazon rainforest, we are seeing the global effects of climate change caused by people,” said Vitek Jirinec, lead author on the study.
The scientists have studied measurements and weigh-ins of 77 different bird species in the Amazon rainforest since the early 1980s. Nearly all of the bird species have gotten lighter as time goes on. On average, most species became about 2% lighter every decade. These birds don’t vary that much in size,” said co-author Philip Stouffer, a professor of conservation biology at Louisiana State University. “But when everyone in the population is a couple of grams smaller, it’s significant.”
The researchers found that bird species living in higher parts of the forest—as opposed to closer to the forest floor —saw the most pronounced changes in terms of body composition. Those are the species most exposed to high temperatures. Longer wings and smaller bodies mean that birds have to useless energy to move around, helping them stay cool.
Brian Weeks of the University of Michigan in 2019 researched the average sizes of 52 species of migratory birds in North America from 1978 to 2016. He also found all of them had smaller bodies and longer wings in 2016. This is another example of climate change-human actions globally—affecting a fundamental thing such as the size and shape of the birds. The same effect is likely to be true of other species across the world living in extreme environments.

9 . The impact of fast fashion on the environment is significant. Recently Zara, one of the largest fast-fashion retailers (零售商) in the world, put forth a concept that only sustainable fabrics are used in clothing production. But how can Zara ever be sustainable? They produce around 450 million garments (衣服) a year and release 500 new designs a week, about 20,000 a year. Zara’s fast-fashion model has been so successful it has inspired an entire industry to follow them.
Clothing production doubled from 2012 to 2022. The average consumer bought 60 percent more clothing in 2022 than in 2012, but kept each garment half as long. And less than one percent of all clothing produced globally is recycled.
I spend a lot of time reading the corporate social responsibility reports of large brands and interviewing micro-to-small sized enterprises to see how they approach sustainability. The largest significant difference between them is culture.
Small brands focus on creating a culture of sustainability by using strategies like producing made-to-order, so they are not making more than what is sold. Most small brands are opting to work under, an “anti-fashion calendar”. They choose not to follow the intense seasonal calendar that fashion functions under. They do this because waste is one of their biggest concerns. They also design clothing to be of the highest quality, ensuring durability and longevity, so you may keep it longer.
Fast fashion is a “grow or die” business, and the fast-fashion growth model used by all large companies is predicated on limitless growth. Large global corporate retailers are not seeking to change their fundamental business model or create cultures of sustainability. That would require re-working their entire business structure and ultimately hurt their bottom line.
I would start to believe Zara and other large fashion brands had good intentions to fight climate change if they started to look at how to move away from their continuous offerings of weekly new products. They need to introduce alternative sustainable business model practices. One small step could be to offer repair or tailoring services. Tailoring creates clothes that fit perfectly, subsequently increasing their emotional value, so that we love them and keep them longer.

10 . A key part of protecting endangered species is figuring out where they’re living. Using environmental DNA, or eDNA, to track species isn’t new. For a few years now, researchers have been using DNA in water.
Two teams of scientists — one in Denmark led by Dr Kristine Bohmann and one in the UK led by Dr Elizabeth Clare — came up with the same question at about the same time: Could they identify the animals in an area from DNA that was simply floating in the air? DNA in the air is usually so small that it would take a microscope to see it. “I thought the chances of collecting animal DNA from air would be slim though much time had been spent on it, but we moved on,” said Bohmann who was trying to think of a crazy research idea for a Danish foundation that funds far-out science.
One team collected samples from different locations at Denmark’s Copenhagen Zoo, and the other at Hamerton Zoo Park in the UK. Clearly, they both chose the zoos. “We realized we have the Copenhagen Zoo,” Bohmann recalls. In fact, both the zoos in the UK and Denmark were almost like the zoos that were custom-built for the experiments: The animals in the zoos were non-native, so they really stuck out in DNA analyses. “If we detect a flamingo (火烈鸟), we’re sure it’s not coming from anywhere else but the zoo,” Bohmann says.
In the laboratory, by comparing their samples with examples of DNA from different animals, the scientists succeeded in identifying many different animals at the zoos.
Neither team knew that the other team was working on a similar experiment. The two were nearing submission to a scientific journal when they discovered about the other experiment. Rather than compete to rush out a publication first, they got in touch and decided to publish their findings as a pair. “We both thought the papers are stronger together,” says Clare.
“The next step is to figure out how to take this method into nature to track animals that are hard to spot, including endangered animals,” says Bohmann.
