The flooding
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.

3 . 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.

5 . 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.
| A．Many dogs can tell smelly gas. |
| B．Your dog may run off or hide under a bed. |

| D．If there is a coming earthquake, your dog will act strangely. |
| E．They will also often bark for what seems to be no right reason. |
| F．Earthquakes generally come with no warning and are hard to predict. |
| G．There may be other reasons dogs may act this way or appear afraid for seemingly no reason. |
Tomatoes: The Real Magical Fruit
“Fresh tomato plants! Straight out of the ground! 50 cents each!” I shouted in the school hall. In my hands, I carried a shoebox with little tomato plants. Their homes were plastic bottles, without the top half. Most people ignored my product, but some handed me 50 cents and picked out a 2-week-old baby tomato plant.
About a month before this, I started gardening. I pulled up grass in my little garden for several days in a row. Satisfied with my work, I continued to the second step — begging my dad to take me to the supermarket. He agreed!
When my dad turned off the engine and opened the door, I practically skipped inside the supermarket. We headed straight for the garden center. I picked up planters, seeds and dirt. My dad helped and showed me the best dirt and tomato plant types to get. We got to the register, and my dad, knowing what would happen, helped me pay.
As soon as I got home, I began to plant them in my garden. The following days witnessed my visits to the garden and my parents were amazed by my devotion to my new-found love.
Then was the part where I met my problem — I planted too many tomato seeds. I realized this all too late, about 10 days later when they all started sprouting (发芽) up and I counted 45 tomato plants. A few days went by and then I ended up with 85 tomato plants.
I did what all high schoolers would do when they messed up — I asked people around. I even got a notebook to write down their suggestions. Sadly, I got the same answer from most people, “Just let them die.” WHAT?! Let my beautiful plants die? They had so much potential! They could make 20 — 30 tomatoes per plant! We were talking about the possibility of around 2,550 tomatoes!

Mauna Loa, the world’s largest active volcano, started erupting late Sunday in the U.S. island state of Hawaii in the Pacific Ocean. The volcano last erupted 38 years ago. But it is not expected to put people in danger.
At this point, melted(熔化的) rock, called lava, is predicted not to come near populated areas, but officials warned people to be ready to move away. The path of lava flows can change quickly.
Island officials warned people to stay away from the areas where lava is coming out because it can shoot 30 to 60 meters in the air. The gas coming from the eruption is also harmful. At the moment, however, the state said air quality on the island is good.
The eruption is a new experience for many people on the island. There are more than twice as many people living there compared to the last time Mauna Loa erupted. State officials are most concerned about an area about 50 kilometers to the south of the volcano where about 5,000 people live.
There is some concern about a weak area on the southwestern part of the mountain. If lava escapes from that area, it could threaten places where people live in just hours or days. The lava has never come up through that area during past eruptions.
The lava could flow toward the city of Hilo, which has about 45,000 people. That could take about a week. Scientists say they hope the lava flows like it did in 1984, when it moved slowly.
Hawaii mayor is Mitch Roth. He said the eruption “will be remarkable”, but he does not think it will cause problems for people visiting Hawaii. He said many people come to Hawaii to see volcanoes, but they have to travel a long way to a national park. Now, they can see an eruption much more easily. “You can just look out your window at night and you’ll be able to see Mauna Loa erupting,” he said.

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 . 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.

10 . 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.
