1 . Earthquakes are a terrible natural disaster that will cause lots of danger and damage. In the last few years, we have seen some of the worst earthquakes in history.
Dogs have been known to warm their owners that dangerous weather was coming. We can take the ways our dog reacts (反应) in certain situations to give us a hand in predicting when something like an earthquake may be about to happen.
Although the signs of a dog sensing an earthquake aren’t very clear, dogs who sense earthquakes will show certain signs before the event actually happens.
On the other hand, dogs will instinctively look for shelter when they sense bad weather or they feel like they are in danger.

3 . The Banaue Rice Terraces (梯田) in Ifugao Province in the Philippines offer a great sight. This UNESCO World Heritage Site is also rich in history and features how human creativity can produce amazing outcomes. Through hard work, the Ifugao native managed to survive by flattening the mountain’s surface layer by layer and using them as farmlands. This practice of more than two thousand years has put together a well-known wonder.
There are several rice terraces in the Ifugao region but the Banaue Rice Terraces are the most popular tourist spot. The photos of this area are often used in printed materials like textbooks magazines and postcards. After getting a good look at the rice terraces, I was reminded of the first time that I saw their pictures in our textbook during my elementary days. I already found them amusing as a kid and seeing their beauty as an adult got me more amazed.
The tourism officer told us that we were lucky to catch them in their greenest form. If you plan to visit this tourist spot as well, you should take note that we got there last June 1. You can also take into consideration that the rice planting cycle is typically 3 to 6 months.
Unlike the other terraces, the local government created a platform that makes it easy for everyone to get a closer look at the rice terraces. The platform has four stone statues that they refer to as rice protectors.
It’s sad that the younger generation of Ifugaos are slowly abandoning the rice terraces. According to tour guide Alvin, the part of the rice terraces where people can see thick bushes and trees were former rice fields. But the children who inherited (继承) those decided to give up farming and work in big cities instead. I hope that a new farming method with modern equipment will encourage the Ifugaos to continue their rice terraces farming tradition to protect this cultural treasure.

4 . Cities have been described as essential to climate change solutions, but they can also raise the kinds of ecologists that will bring us into a more comprehensive biological future.
As a black wildlife biologist from Philadelphia, I stood out among my coworkers. My presence in ecology has challenged assumptions about not only what a biologist looks like, but also where a biologist comes from. In the U.S., ecology was and is mainly white and conducted in rural landscapes, but I had no history of camping, fishing, hunting or hiking. I had yet to recognize that Philadelphia, with its four seasons and richness of squirrels (松鼠), row homes and festivals, was actually my first ecological classroom. There I witnessed wild cats eating birds and rats, people shooting bats from their homes and snakes being killed by lawn mowers (割草机). This is as much ecology in action as anything we witness in fields and forests.
Urban wild animals exhibit many features and behaviors that set them apart from their rural twins: they may be bigger, eat more diverse food sources, are active at different times of the day, move differently and have different personalities. Some biologists argue they are even “smarter”. Besides, urban wildlife balances more risks—such as road chemical poisons and diseases from domestic animals—with rewards. Some of those rewards come from humans providing food and some from the distribution of our parks and water bodies.
In our professional lives as biologists, living with such wild animals can make us more tolerant of species diversity, which can benefit the natural world. Nature is no longer only primitive wilderness but includes sounds of human laughter and garbage trucks. We expect more biologists from urban settings because urban environments naturally train keen observers who are the future of ecology.

5 . Victoria Falls is one of the Seven Natural Wonders of the World. Statistically speaking, it is the largest waterfall in the world. Victoria Falls is located on the border between Zambia and Zimbabwe. The falls are also close to the border of Botswana. The Zambezi River, which originates in northern Zambia, serves as the falls’ water source.
There are basically two seasons for the Victoria Falls area. The rainy season runs from late November to early April with the remaining months accounting for the dry season. One would imagine that the rainy season with more water would make the falls more spectacular (壮观的), however, the additional water and subsequent mist(水汽) in the air makes it nearly impossible to see the base of the falls.
The months of June and July are probably the best time to view the falls. The water levels are still high enough to show the beauty of the falls, but the amount of water is less, creating less mist and more visibility of the falls.
As you move into the later part of the dry season, August through October, it is quite possible that you will see more rock face than falls. However, this also opens the door for walking across the top of the falls, which can be a unique and exhilarating experience as well.
During the rainy season and high water, Victoria Falls can be a challenge to capture (抓拍) with a camera because of all of the mist in the air. However, this increases the probabilities that you will be able to capture rainbow images around the falls.
The lower water levels can create more dramatic pictures with various rocks cropping out between the falls. You should also be able to see the canyon and base of the falls. You will also be able to walk across the top of the falls and take images down the face of the falls.

6 . In 2015, the last golden eagle in England died at Haweswater in the Lake District National Park. Its death was the latest in a series of losses in the Lake District. In his book, Wild Fell, published by Doubleday on 24 February 2022. Haweswater Site Manager Lee Schofield calls on the local people to revive the landscape—telling the ups and downs of taking over the management of two hill farms in 2012 and how his team are combining ancient practices with new ambition so that farming and nature can develop well, and that one day eagles may surge once again.
In the Lake District, Lee and his team, working with landowner United Utilities, have changed a polluted river, restored wetlands, and equipped cows with GPS collars to protect endangered wildflowers. As well as helping wildlife, this is also good for people—there are twice as many people working at Haweswater than a decade ago, thousands of tons of carbon are being locked away in new woodlands and restored wetlands, and changing the river has added 180m to its length, slowing the flow of water and reducing flood risk. By restoring the habitats in the area, it will also finally help improve the water quality in the reservoir at Haweswater that provides water for more than two million people across North West England.
Lee says, “Change is possible, but we can’t depend on reserves as lifeboats for nature—we need a great transformation with people and wildlife at the heart of every decision made up and down this country. Wild Fell is not intended to be an instruction book, and there’s never a one-size-fits-all solution, but I hope it can serve as an example of what can happen when we work together to fight for our wildlife and our livelihoods.” Isabella Tree, author of The Return of Nature to a British Farm, says of Wild Fell, “It is an inspiring journey into the restoration of our lands. Reasoned, intelligent and well-informed, this is a story of hope and renewal for both nature and farming.”

8 . He’s as big as a small golden dog and covered with scales (鳞片). He is the pangolin (穿山甲), an endangered animal.
According to the wildlife trade monitoring organization Traffic, about one million pangolins were killed from 2000 through 2013, mainly for their scales, which are used in medicine. Pangolins are sensitive creatures and picky eaters that only eat certain species of ants, a diet that’s very difficult to copy in the food chain.
“In the last decade, there’s been a huge growth trade in pangolins between continents, especially their scales,” says Dan Challender, chair of the pangolin specialist group. Previously, most pangolin killing happened within Asia, he says. This shift means that Asian pangolins are becoming difficult to find but that the value of the scales makes it worth the extra cost to take pangolins from Africa to Asia secretly.
All eight species of pangolins, four in Africa and four in Asia, are in danger of extinction due to the illegal trade. International trade in the four species of Asian pangolins has been banned since 2000. In the past few years, a ban on international commercial trade in all eight species has gone into effect. It was voted by 183 governments that are parties to the Convention on International Trade in Endangered Species (CITES), which is in charge of cross-border trade in wild animals and their parts.
Pangolins are eaten as bushmeat in western and central Africa and by some local groups in South and Southeast Asia. Their parts also are used in Ghana, Nigeria, South Africa, and elsewhere in sub-Saharan Africa as traditional medicine. Typically dried, ground into powder, and put into pills, pangolin scales are used in a range of traditional medicines to help mothers who have given birth to babies to recover. But they are now endangered. Perhaps no pangolins can be seen when our next generation grow up.

9 . Scientists from Deakin University in Australia have traced how about 30 species changed across various time periods in response to rising temperatures. They searched through nearly 100 past studies by other researchers, and tracked comparisons that date back a century or two in some cases. They found many creatures are changing the sizes and shapes of certain body parts.
“Warm-blooded animals in the wild rely on their own bodies to avoid overheating. They release heat through their appendages (肢体),” explains Sara Ryding, who led the study. For little creatures. like mice, tails do the job. For birds, their bills (喙) do the work.
The animals’ shape-shifting changes make sense, researchers say. In biology, an established concept called Bergmann’s rule shows that creatures that live in colder climates tend to be larger and thicker than those closer to the equator (赤道). Later, a biologist, Joel Asaph Allen further expanded the concept, saying that animals that adapted to cold climates have shorter limbs (肢) and bodily appendages — to keep the warmth in. For similar reasons, in hotter climates, warm-blooded animals"appendages become larger, relative to their body size. Larger appendages can help animals release more heat into the surrounding air.
Ryding’s team also conducted various field studies. One of them measured the bills of Galapagos finches from 2003 to 2011 and found they enlarged in response to temperature rises. Other data the researchers analyzed focused on European rabbits, which were brought to Australia and settled in areas with different weather. Those that found themselves in hotter places developed longer ears over time.
However, the researchers aren’t sure whether this shape-shifting is a good development. If larger ears or bills can help the animal cool off, that’s a good thing. But certain changes may damage some creatures’ ability to hunt for food. “If you’re a hummingbird and your bill is getting broader and wider, it may become too large to effectively feed on flowers where you’ re drawing your nutrition from,” says Ryding.

10 . Plants don’t have ears or a central nervous system, but new research out of the University of Missouri has demonstrated that they might still have the ability to “hear”. More specifically, plants have been shown to exhibit an immune (免疫) response to the mere sound of a hungry insect.
For the study, researchers played the sound of a caterpillar chewing to a group of plants, which caused slight vibrations (振动) on the plants’ leaves. The plants were able to recognize these vibration patterns as danger, and responded by mounting the appropriate immune response. In other words, it appears that plants can “hear” themselves being chewed on.
Researchers assume that plants achieve this remarkable ability thanks to proteins that respond to pressure found within their cell membranes. Vibrations cause pressure changes within the cell, which can change the behavior of the proteins; however, additional study will be required to confirm or deny this theory.
Once researchers identify the exact mechanisms at play in this process, it could lead to advances in crop protection. Farmers could potentially learn to use sound to cause a plant’s natural chemical defenses against insect threats, rather than turning to poisonous chemicals.
“We can imagine applications of this where plants could be treated with sound or genetically engineered to respond to certain sounds that would be useful for agriculture,” said study author Heidi Appel.
The study adds to the growing list of ways that plants have been shown to sense their environments. They are not the boring organisms that many people assume they are. For instance, some plants are able to communicate with each other and signal upcoming danger to their neighbors by releasing chemicals into the air. Plants can respond to light (think about sunflowers) and temperature. Some can even respond to touch, such as the Venus flytrap (捕蝇草), which snaps shut when an insect stimulates its hairs.
