1 . The first rule of popular science is to reveal the wonder and mystery of the world. For that reason, Sentient (Picador), written by photographer and wildlife film-maker Jackie Higgins, is my pick of the year. According to my interviews with many readers, I select other four newly-published books in 2022.
Delicious
This book describes how our ancestors hunted and consumed ancient animals such as mammoths, bison, giant camels and many more now-extinct species. The diet of the Clovis peoples of North America was a menu described as “a record of a lost world”. This book explains how our dinners robbed the world of so many large animals. It gives inspiration for how modern humans can be at peace with nature.
The New Climate War
In 1999, Mann published a graph showing the rapid post-industrial rise in global temperatures. Two decades later, his book The New Climate War remains convinced that we can prevent climate change. This book sets out a common-sense approach to carbon pricing and a revision of the Green New Deal. Of course, there are still many people who deny that climate change is even happening.
The Geodesic Dome
Physicist Kate Greene imagines that she spends four months in a geodesic dome in Hawaii, with five other people, to mimic living in a colony on another planet. The story describes the future of our Earth. Kate makes readers cherish the natural environment. “No sunshine on our skin, and no fresh air in our lungs,” Greene turns the frustrations into a moving story.
Florida Scrub-Jay
The birds were once common across the peninsula. But as development over the last 100 years reduced the habitats on which the bird depends, the species became endangered. Mark Walters travels the state to report on the natural history and the current situation of Florida’s flag ship birds. This book can raise people’s awareness of protecting the birds’ habitats.

2 . With greater climate disasters lying ahead, it is natural for us to make every effort to stop a series of floods, unusual snowstorms, and alarming reports from scientists. For many of us, part of that means running out to buy reusable drinking tubes, organic cleaners, and packaging-free products.
However, before you are joyful of your “green” purchases, take a second to consider a principle that should be obvious: simply consuming less is better for the planet. After all, every new item a factory pumps out requires some resources to produce. But in the confusing stream of environmental news, this simple truth can get lost. Take plastic bag bans for instance. If your city is getting rid of single-use shopping bags, it can be tempting to pay for that fashionable organic cotton bag hanging in the check-outline of supermarkets. However, experts who have analyzed the data on environmental impact insist that growing cotton is actually no better for the Earth than producing the conventional plastic bag. Any bag you already own is your best bet for carrying your groceries if you care about sustainability.
It is not just the Earth that will be happier if you buy less. You will feel more contented too. There is a common view that green buying patterns mean people are going green. However, it doesn’t seem to be that way. Reduced consumption has positive effects on increased well-being, but you don’t see that with “green” consumption.
Many studies have shown that materialism in general makes us unhappy and lonely. It is perfectly possible to be a materialist and an environmentalist at the same time. Lusting (欲望) for every new “green” product on the market might make you feel good about yourself but it presents the same emotional traps as lusting for whatever the Joneses next door are buying. If you relieve yourself of that burden of ownership, most people report feeling a lot better and freer.

G.The plus invites people to continue their action even after Earth Hour is finished. |
4 . Lisa Gautier receives nearly a dozen parcels of human hair every day. With her San-Francisco-based non-profit organization Matter of Trust, Gautier turns donated hair into mats used to soak up oil spills on land, and booms(long tubes)used for spills at sea.
A standard way to clean up oil from land is to use mats made from polypropylene(聚丙烯). But polypropylene is a non-biodegradable plastic, and producing it ultimately means more drilling for oil. Hair, by contrast, is an environmentally friendly resource that can soak up around five times its weight in oil, according to Matter of Trust, and it is abundant.
Oil spills can pollute drinking water, endanger public health, harm plants and wildlife, and damage the economy. According to Gautier, the spills that hit the headlines only make up 5% of global oil pollution.
Megan Murray, an environmental biologist at the University of Technology Sydney, develops sustainable technologies to tackle oil spills. Her research indicates that as well as being biodegradable, human hair is often just as effective as polypropylene, and in some circumstances even better. “The hair mats are very beneficial to land spills,” says Murray but adds that when raw oil is spilled on beach sand, it is very difficult to absorb it using any of the materials she has tested. Another advantage of hair is that it costs less than conventional materials and is “globally available as a recycled material,” she says.
However, Murray cautions that hair mats are not a perfect solution, because they are single-use, and can only be dealt with by burning or by burying into soil which then isn’t suitable for growing food. She is now researching methods to extract the oil from a used hair mat, meaning both can be reused.
As the hair mat designs aren’t under patent, other groups have begun producing their own mats and booms. Gautier is pleased to see the movement growing. “Anyone can make a hair mat,” she says. “It creates green jobs, it cleans water, it reduces waste in landfill, and it’s promoting renewable resources.”

5 . Vast lands of America are dominated by corn, nearly 100macres of it, stretching from Ohio to the Dakotas. What once was forest today produces the corn that feeds people, cattle and, when made into ethanol (乙醇), cars.
Now, the nation’s airlines want to power their planes with corn, too. United Airlines signed a deal with a Nebraska ethanol company to buy enough sustainable fuel, to power 50,000 flights a year. The government could decide on its tax incentives (税收激励) for the industry as soon as December. “Mark my words, the next 20 years, corn farmers are going to provide 95% of all the sustainable airline fuel,” President Biden said in July.
The airlines’ ambitious goal would likely require nearly doubling ethanol production, which airlines say, with great expectation, would decrease their greenhouse gas emissions. If they succeed, it could transform America’s Corn Belt, stimulating farmers and ethanol producers, but potentially further damaging one of the nation’s most important resources: groundwater.
Corn requires a lot of water to grow and it can take hundreds of gallons to produce a single gallon of ethanol. But as airlines take the idea of ethanol, the vital groundwater faces serious risks. “We’re on track to massively increase water usage without any real sense of how sensitive our groundwater is,” said Jeffrey Broberg, who is concerned about groundwater in Minnesota, a major corn state.
The Department of Energy said in a statement that “water use is a critical part of the conversation surrounding bio-energy sustainability”. It pointed to a 2022 department study that concluded that the United States could significantly reduce pressure on groundwater by shifting fuel production away from water-intensive crops like corn, instead growing more crops that don’t require irrigation (灌溉), like various types of straw, grasses and trees. Hopefully, a better approach will be soon studied and adopted.

6 . Buying furniture is easier than ever. You can even order a new table and chairs online without ever leaving home. But did you ever think about how furniture is made? The process begins with trees but now researchers have found a better way: growing it in a lab instead of a forest. Instead of cutting down trees and adding to deforestation, Velasquez-Garcia said, “If you want a table, then you should just grow a table.”
The research group found a way to actually grow plant tissue (组织) — wood and fiber — in a lab that is similar to the way cultured meat is grown. While there is still a long way to go to actually grow a table, the team was able to grow structures from cells from zinnia leaves.
Making furniture and other items from biomaterials could eliminate cutting down trees in forests. “The way we get these materials hasn’t changed in centuries and is very inefficient,” said Velasquez-Garcia. “This is a real chance to avoid all that inefficiency.”
There are other benefits to using lab wood too. Lab grown wood can be handled to take on any shape — like 3 D printing — so it may be possible to build a table without glue or screwing parts together.
Beckwith, a mechanical engineering PhD student, was inspired by a visit to a farm to try to make land-use more efficient and environmentally sound. “That got me thinking: Can we be more strategic (战略上的) about what we’re getting out of our process? Can we get more yield for our inputs?” she told MIT News. “I wanted to find a more efficient way to use land and resources so that we could let more farmlands remain wild, or to remain lower production but allow for greater biodiversity.”
Today, the two largest uses of trees are to make wood products and paper. When new biomaterials become readily available, forests will lose their economic value and will be preserved for their environmental, health, and recreational value. These researchers, like Velasquez-Garcia, are speaking for the trees.

7 . Chinese scientists say they have developed a robotic fish that can remove microplastic particles from water environments. Researchers working on the project say the robots could help to clean up plastic pollution in oceans around the world.
The robotic swimmers are about 1.3 centimeters long. They are made of a soft chemical Compound. The robots are designed to absorb microplastics while moving through the water. The project was launched by a team at Sichuan University in southwestern China. The researchers said the robots have already performed well in shallow water and they plan to carry out more tests in deeper waters. The scientists reported their findings in a new study in Nano Letters. The publication comes from the American Chemical Society, a nonprofit organization supported by the U.S. Congress. The robotic fish were built to target microplastic particles, which are smaller than five millimeters. Studies have confirmed that microplastic pollution has been discovered in many natural environments. The material comes from the breakdown of manufactured plastic products and industrial waste.
The team said the robots can be controlled by light. Turning “a near-infrared light laser” on and off causes the fish’s tail to move back and forth, the American Chemical Society said. The robotic fish can swim up to 2.76 body lengths per second. The researchers said this is faster than most similar soft robots. Wang Yuyan was a member of Sichuan University’s research team. She told Reuters news agency that the small, lightweight robot is currently being used to collect microplastics for research purposes. But Wang added that the team plans to expand that use so the robot fish can remove larger amounts of microplastic waste from deep ocean areas. The fish can take in different kinds of microplastics and even repair itself when damaged, the researchers said. And if a robot fish is accidentally eaten by a real fish, it could safely digest the material, the team added. Wang said similar robots could be developed to be placed inside the human body to remove unwanted materials or disease.

F.Foods need proper storage to prevent them going bad. |
G.If you can’t see what foods you have, you’ll forget them. |
9 . The sunflower sea star has been listed as a critically endangered species following a groundbreaking population study led by Oregon State University (OSU) and The Nature Conservancy.
“These giant sea stars used to be easy to find and were a hit with divers. Unfortunately, your chances of finding one now are next to nothing in most of the areas near the United States—this listing is one step to extinction—and I don’t think they’re coming back without help,” said OSU’s Sarah Gravem, a research associate in the College of Science and the lead author of the study.
Populations of the sunflower sea star suffered dramatic crashes because of a marine (海洋的) wildlife epidemic event, which began in 2013. Scientists used more than 61,000 population surveys from 31 data sets to calculate a 90.6% decline in the sunflower sea stars and estimated that as many as 5.75 billion animals died from the disease, whose cause has not been determined. Moreover, the research showed no sign of population recovery in any region in the five to seven years since the event.
Sunflower sea stars are a key catcher of purple sea urchins (海胆) and the sea star decline has helped the increase in the urchin population in many regions. Too many urchins are linked to a decline in kelp forests(海藻林) already facing pressure from marine heat wave events, making the future uncertain for ecosystems that provide habitat for thousands of marine animals and help support coastal economies.
“Because most people are not out in the ocean every day, we don’t realize how much it’s being changed and impacted by humans. We need to think about how to keep our ocean healthy. While reducing the release of carbon dioxide is the most pressing need, rebuilding key catcher populations, like the sunflower sea star, can be an important piece of the puzzle too,” said study co-author Sara Hamilton, a Ph. D. candidate in the OSU College of Science.

10 . With greater climate catastrophe (气候突变) on Earth, it is natural for us to make every effort to stop the potential floods, snowstorms, and alarming reports from scientists. For many of us (myself included), part of that means running out to buy reusable straws, organic cleaners, and packaging-free products.
However, before you are delighted at “green” purchases, take a second to consider the results of a new study from Arizona University. By comparing the shopping habits, mental health and environmental impact of young people, the researchers reconfirmed a principle: Buying less beats buying “green” stuff without effort. And that is true whether you are looking at the impact that your purchases have on the Earth or on your own happiness.
It should not come as a shock that simply consuming less is better for the planet. After all, every new item a factory yields requires some resources to produce. Take plastic bag bans for instance. If your city is getting rid of single-use shopping bags, it can be attractive to pay for a fashionable organic cotton bag hanging in the check-out line of your local supermarket. However, experts insist that growing cotton is actually no better for the Earth than producing the conventional plastic bags. Then what is your best bet for carrying your groceries if you care about sustainability? Any bag you already own.
It is not just the Earth that will be happier if you buy less. You will feel more contented too, according to the new study. “People believe that they might well be self-satisfied about becoming environmentally conscious through ‘green’ buying patterns, but it doesn’t seem to be that way”, said the lead researcher Sabrina Helm. “Reduced consumption has effects on increased well-being, but we don’t see that with ‘green’ consumption.”
“Owning every new ‘green’ product on the market might make you feel contented, but if you relieve yourself of that burden of ownership, most people report feeling a lot better,” said Helm.
