2 . Researcher Ruijia Hu said wildlife habitat in crowded places like south went Ohio is becoming increasingly fragmented (分散) as forests give way to new construction. Eventually, this could make trouble to an animal with specific habitat needs like Ohio’s pileated (红冠) woodpecker.
Pileated woodpeckers have the nickname carpenter birds for their never-ending natural woodworking. They peck out holes in trees for their nests every year, creating lots of valuable homes for animals like fox squirrels and owls. “They make new nests every year. They won’t reuse old ones,” Hu said. “Other animals depend on them.”
Pileated woodpeckers are private birds that are more often heard than seen. Studying them can be especially difficult. So Hu turned to citizen science for help. To identify where woodpeckers have been seen, she used eight years of sightings collected by birders and logged into the website eBird, a free online tool and app that anyone can use to record their observations and locations. She overlaid these sightings with remote sensing data and found that corridors along rivers and creeks with abundant mature trees and deadwood helped the birds adjust to their increasingly fragmented urban landscape.
“With fragmented forests, many habitats that were once suitable for wildlife are broken up,” Hu sa id. “Wildlife is unable to find habitat big enough to meet their survival needs. And even if there are suitable habitats, the distance between them can be too great. Wildlife corridors link up these habitat patches. Since wildlife can travel and migrate from one patch to another, the probability of finding food and shelter is higher.”
“There are so many species in urban areas that we don’t pay attention to, especially when they’re not considered vulnerable,” Hu said. “With development chipping away at more forest in this crowded county, the tipping point (临界点) could come quickly and unexpectedly. You can’t fix it overnight. It’s not just about planting more trees. The birds need mature forest, so it could take 30 to 50 years to replace their habitat. At least we can protect these riverside forest corridors and see that existing trees reach maturity.”

4 . The rechargeable lithium-ion (锂离子) battery market is worth more than ＄50 billion. Lithium-ion batteries, whose demand continues to go up day by day, are used in a wide range of electronic devices. They are made of four main components, and cathode (阴极) is one of them. The cathode’s active material type is what determines the capacity of a battery.
A recent study, led by Wang Yan, a material scientist of Worcester Polytechnic Institute, finds that lithium-ion batteries made with recycled cathodes work better than those with new cathodes.
“The battery industry is expected to grow sharply in the next decade. This high demand has led companies to go to extremes, like increasing deep-sea mining, to gain access to the minerals used in lithium-ion batteries,” Wang said. “Mining minerals will have environmental impacts. Recycling spent lithium-ion batteries offers a way out.”
But until now, the prospect of using recycled materials in lithium-ion batteries has some manufacturers (制造商) worrying that it could impact performance. Thus, lithium-ion batteries are still not widely recycled. Aware of decreasing resources and environmental impact, Wang and other researchers set out to find a way to make recycling lithium-ion batteries economically practical. Through experiments, they could recover more than 90% of the key metals from spent batteries. These recovered metals became the basis of the new recycled battery’s cathode’s active material.
In tests between Wang’s team’s recycled batteries and brand-new batteries of the same composition, the recycled batteries outperform the new ones in their ability to maintain capacity. It took 11,600 charge cycles for recycled cathode batteries to lose 30 percent of their original capacity. That was about 50 percent better than the 7,600 observed cycles for new cathode batteries, the team reported. Those thousands of extra cycles could translate into years of better battery performance, even after repeated use and recharging.

5 . Michael Gonsalves, a chef of Golden Oak at Disney World, has a cuisine concept rooted in fresh, locally-sourced ingredients that originated from childhood harvesting produce from their family garden with his mom to eventually leading kitchens at Walt Disney World Resorts to employ a sustainable model.
“Truly the whole process starts with menu planning,” he said. Creating one dish leads into the creation of many more through the end-to-end use of products. As chefs, they are always searching for the best ingredients. It is then their focus to ensure they appreciate and respect all that go into each and every one of them. For example, they source chicken that is naturally grown and fed on a natural plant forward diet, no hormones (激素) or additives — that’s used in many ways throughout menus from a simple grilled chicken breast to bone soup. Nothing goes to waste.
When they do have waste, even if minimal, they shift it from landfills to transform it into compost (堆肥) that’s then used across the Walt Disney World property. They also support Second Harvest, a local community food bank where healthy produce, prepared, but not served, meals eatable for human consumption are donated. Disney also works with pig farmers when they can’t distribute foods past the point of safety for human consumption. Besides, wildlife reservations love to get the meat because tigers and wild cats can still eat that.
Their operations are “on a path to a sustainable zero waste kitchen of tomorrow” where chefs learn the full-life cycle of plants from seed to plate and gain a better understanding and appreciation for the product and their craft.
Golden Oak at Disney has millions of bees that produce up to 300 pounds of honey per year, plus those bees help with cross pollination (授粉) of their gardens on a daily basis. They advocate a culture that helps develop not only the quality of food, but an appreciation for nature.

6 . One man’s trash is another man’s treasure is absolutely the case in Turkey where garbage collectors started collecting books that have been thrown away and ended up opening a library.
It started when garbage man Durson Ipek found a bag of abandoned books when he was working and then it snowballed from there. Ipek and other garbage men started gathering the books they found on the streets that were ready for landfills (垃圾填埋地) and as their collection started to grow, so did word of mouth. Soon, local residents started donating books directly. The library was initially available only to the garbage employees and their families to use but as the collection grew, so did public interest and the library was opened to the public in 2017.
“On the one hand, there were those who were leaving these books on the streets. On the other hand, others were looking for these books,” Ankaya mayor Alper Tasdelen told CNN. “We started to discuss the idea of creating a library from these books. When everyone supported it, this project happened.”
All the books that are found are sorted and checked for condition. If they pass, they go on the shelves. Today, the library has over 6,000 books that range from fiction to nonfiction and there’s a very popular children’s section that even has a collection of comic books. An entire section is devoted to scientific research and there are also books available in English and French. The collection has grown so large that the library loans books to schools and educational programs.
“Village school teachers from all over Turkey are requesting books,” Tasdelen told CNN. The government has to hire a full-time employee to manage the library.
This library is incredibly popular. It is frequently filled with the children of the city’s workers and students from nearby schools. There is a waiting room set up for readers and chess boards for the people who visit the library. You can even enjoy a cup of tea in the waiting room.

7 . Baggy has become the first dog in the UK—and potentially the world—to join the fight against air pollution by recording pollutant levels near the ground.
Baggy wears a pollution monitor on her collar so she can take data measurements close to the ground. Her monitor has shown that air pollution levels are higher closer to ground level, which has helped highlight concerns that babies and young kids may be at higher risk of developing lung problems.
Conventional air pollution monitors are normally fixed on lampposts at about nine feet in the air. However, since Baggy stands at about the same height as a child in a pushchair（婴儿车）, she frequently records pollution levels which are much higher than the data gathered by the Environment A gency.
The doggy data research was the idea of Baggy's 13-year-old owner Tom Hunt and his dad Matt. The English youngster noticed that pollution levels are around two-thirds higher close to the ground than they are in the air at the height where they are recorded by the agency. Tom has since reported the shocking findings to the government in an attempt to emphasise that babies are at higher risk of developing asthma（哮喘）.
Matt Hunt said he was "very proud" of his son because “when the boy gets an idea, he keeps his head down and gets on with it, and he really does want to do some good and stop young kids from getting asthma."
“Tom built up a passion for environmental protection at a very early age," Matt added. “He became very interested in gadgets（小装置）. About one year ago, he got this new piece of tech which is like a test tube. One Sunday afternoon, we went out to do some monitoring, and he said, why don't we put it on Baggy's collar and let her monitor the pollution？'So we did it."
Tom said, "Most of the time, Baggy is just like any other dog. But for the rest of the time she is a super dog, and we are all really proud of her."

8 . This 3-mile stretch of sand and tide pools beneath a castle of 80-foot cliffs is a California tourism poster if there ever was one. Nothing disturbs the perfect, sunny view, except — once you’re aware of them — microplastic particles (颗粒). But you have to look close-on-your-hands-and-knees close-to see one. And once you do, you see another and another — so many that you may not think of this, or any beach, the same way again. These tiny preproduction plastic balls that manufacturers (生产商) melt down to form everything have been escaping factories, container ships, trains, trucks — and public notice — for decades.
The 2- to 3-millimeter, multicolored balls are a subset (子集) of microplastic-plastic particles less than 5 millimeters in size. Microplastic particles accumulate where water takes them, and they’ve been found on shorelines of every continent.
Dr McReynolds is an environmental scientist who’s now joined a global movement studying their trail into the environment. Establishing a baseline count of the presence of microplastic particles — and, more broadly, any microplastics — is the focus of Dr McReynolds’ scientific study here. Charting the count, noting tide, current, and weather conditions will show if amounts are increasing, and perhaps at what rate and why. That knowledge, he says, can inform solutions to plastic pollution such as regulation of their use.
“What are you doing? Picking up trash?” asks a steady stream of beach walkers whenever Dr McReynolds’ crew walks onto the beach and sets up equipment. These are teachable moments for Dr McReynolds.
One recent morning he told some beach walkers how microplastic particles are believed to absorb toxic chemicals, and — because they resemble fish eggs — are eaten by fish and birds and enter the food chain. Almost right on time, a seagull hopped up to a plastic-coated photo of microplastic particles and hungrily pecked (啄食) at it.
Will his work help save the world? Dr McReynolds waves a finger at that idea, “I won’t ever use that word — I won’t save the world from this pollution problem. Preserve it, yes. We want to take care of it.”

9 . Traditionally, profiting from forests often meant capitalizing on timber (木材)——choosing commercial timber. Yet increasingly, there is an understanding that it’s of greater significance to keep trees standing than cut them down for financial profit. Money is not everything. We have to recognize real and lasting value is from natural resources. But money is a fact of life.
Good news is that we can expect entire natural woodland is left undamaged and still provides a revenue (收益) stream. Leaving woodland complete does not necessarily mean that we do not touch it at all. Conservation work may involve building back biodiversity or the removal of foreign plant species.
A healthy woodland system can provide a range of yields (产物). Besides eatable yields——top fruit, berries, and food crops, it produces substances for chemical use. The non-timber forest products provided by natural ecosystems will vary significantly depending on where they are. But there’re almost always ways to explore to acquire revenue.
A project in the U.K. shows woodland is also a draw for visitors. It engages a community who creates a sustainable area of woodland. The sale of handmade wooden items and non-timber forest products is involved. But the community largely obtains revenue by opening up parts of the natural woodland to the public with an adventure playground and outdoor recreational activities on the site. It also offers courses on nest building, special wildlife events and more. The project is thought to have great uniqueness. In terms of revenue, it centers round the existing natural land; the yields woodland can provide become side products.
Recreational activities, tours, and classes are just the commencement. A rich and biodiverse woodland can be an ecosystem that draws in people looking for a beautiful place to stay. Woodland has great value in ecological and social terms. And when you nurse it, it could also add to the income from your land.

10 . Birds’ bodies are becoming smaller in size in response to climate change, even in places like the Amazon rainforest that are relatively untouched by human hands, according to a new study published in the journal Science Advances.
Researchers found that nearly all of the birds’ bodies have become lighter since the 1980s, losing on average about 2% of their body weight every decade. For an average bird species that weighed about 30 grams in the 1980s, the population now averages about 27.6 grams. The study also revealed that wingspan was getting bigger in the Amazon bird species studied.
These birds don’t vary that much in size. When everyone in the population is a couple of grams smaller, it’s significant. This is undoubtedly happening all over and probably not just with birds.
A lower body weight and increasing wing length means that birds use energy more efficiently, the researchers noted. For example, compared with a fighter jet with short wings that needs lots of fuel to fly, a glider plane with a thin body and long wings flies up into the air with much less energy.
The study concluded that a warmer climate was the driving force of these changes. The climate in Brazilian Amazonia, where the birds lived, had gotten hotter and wetter over the study period. Since 1966, rainfall increased by 13% in the wet season and fell by 15% in the dry, with temperatures increasing by 1 degree Celsius in the wet season and 1.65 degrees Celsius in the dry season. The change in climate might have made food or other resources insufficient.
Together, body proportions moved in the direction of more efficient flight and lower metabolic heat production and are consistent with a plastic or genetic adaptation to resource or thermal stress under climate change.
