When you think of a terrible hunter, lions and sharks may first come to your mind. However, some scientists now find that humans are the most terrible hunters. Human activities even bring animals close to extinction. In the last 500 years, more than 300 types of animals have disappeared (消失). How do human activities make the wild animals in danger?
On one hand, hunting and fishing make the number of wild animals become smaller and smaller. Some people hunt animals just for food. It’s a real shame that people in some parts of the world often eat dolphin meat. What’s more, some hunt animals for fashion. Animal skin is used to make coats and bags. Still others hunt animals just for fun. They kill deer and enjoy the excitement of deer hunting.
On the other hand, building more farms or factories causes less and less space for wildlife. Many animals have no comfortable places to live, or enough food to eat. Humans also put animals in danger without going into their living areas. Because of serious pollution from ship traffic and other human activities, the number of wild animals drops greatly.
Luckily, now humans have known the importance of protecting wild animals and already taken action. Our government has made a 10-year fishing ban (禁渔令) on the Yangtze River. Fishermen once fished there for a living. They had to say goodbye to their old job because of the ban. Instead, some fishermen joined a team to clean up rubbish in the Yangtze River and report where to see finless porpoises (江豚). It’s glad to see so many people act to protect animals’ living areas. Keeping on protecting wildlife can make the earth a healthy and beautiful home.

【推荐1】The other side of the wall
There was a young woman who was proud of the growth and care of the flowers in her flower garden. She had been raised by her grandmother, who taught her to love and care for flowers as she herself had done. So, like her grandmother, her flower garden was second to none.
One day while looking through a flower catalogue (目录) she often ordered from, a picture of a plant immediately caught her eye. She had never seen blooms (花) like that before. “I have to have it,” she said to herself, and she immediately ordered it.
When it arrived, she already had a place prepared to plant it. She planted it at the foot of a stone wall at the back of her yard. It grew eagerly, with beautiful green leaves all over the vine (藤), but there were no blooms. Day after day she continued to water it, feed it, and she even talked to it. However, it was useless.
One morning weeks later, as she stood before the vine, she was disappointed that her plant had not bloomed. She was thinking about cutting it down and planting something else in its place.
It was at this point that her neighbor, whose yard was right next to hers, called over to her. “Thank you so much! You can’t imagine how much I have enjoyed the blooms of that vine you planted.” The young woman walked through the gate into her neighbor’s yard, and sure enough, she saw that on the other side of the wall the vine was filled with blooms.
They were indeed the most beautiful blooms she had ever seen. The vine had grown quietly through the crevices (裂痕) and it had not flowered on her side of the wall. It had flowered thickly on the other side.
Just because you cannot see the good result of your work does not mean that it produces no fruit.

【推荐2】If you feel stressed at school, what can you do to make yourself happier? Some may eat their favorite food or listen to some music. Others may go for a walk or get some exercise. A new study found another great way to lower students’ stress—playing with dogs.
Scientists studied 105 students between the ages of eight and nine. 35 trained dogs and their trainers also took part in the test. The children were divided into 3 groups. The students in the first group spent 20 minutes with a dog and its trainer. They watched the trained dogs perform and even played with them. They did this twice a week for 4 weeks. The second group spent the same amount of time (时长) doing exercise to relax. The last group did neither of these things.
During this time, the scientists recorded the students’ cortisol levels (皮质醇水平). Cortisol is a stress hormone (激素). The more stressed you feel, the more cortisol you will have in your body. What did the scientists find? Both the second and third groups showed rises in cortisol levels. The first group, however, showed no big increase. And the children in this group had the lowest cortisol levels right after playing with the dogs.
According to the study, students enjoy playing with dogs, and it helps them become happier. The stress hormone falls over time this way, which is good for students’ health. But here comes the next question: Is 20 minutes of playtime with a dog the best amount of time? Scientists are going to keep working to find out the answer.

Global Footprint Network has been watching the Earth Overshoot Day since 1971. This year, the day came five days earlier than it did last year (Aug. 13th), 11 days earlier that the year before (Aug, 19th) and is the earliest date yet.
Global Footprint Network said that humans now use 1.6 Earths worth of crops, forest, livestock, energy and other resources (资源) every year. By the 2030s we will be using more than two Earth’s worth of resources every year. The situation is more and more serious and the world needs to find better balance in how to use the Earth’s resources.
Overshoot Day is a red light warning of trouble ahead. “That is, we’re using up what our planet does for us, so year after year, there is less for us to use,” Stuart Pimm, an American professor of ecology, explained. “Less forest, fewer fish in the ocean, less productive land.” Two of the main causes are over-population and pollution.
Small actions make a big difference and all of us play an important role in creating a better world where we live. Even a few simple changes around our home can reduce the resource that we waste, from taking a shower instead of a bath, to using our own reusable bags at the store instead of ones that are made of plastics. In this way we can reduce waste and pollution. Let’s start today to live greener in no time.

【推荐1】With more and more rain falling, it’s time for snakes to be active. Living in the city, it never crosses your mind that we might meet them face to face.
Most people are afraid of snakes. They may think snakes are dangerous and ugly. There are more than 2,000 kinds of snakes. Most of them live in mountains or forests, and in cities sometimes we can find them in grass or other dark places. Snakes can’t walk or run because they have no legs or feet, but these long and thin animals can move very fast on their stomachs. Snakes usually have green, yellow or black skins, which make it difficult for their enemies to find them. In winter they hibernate in holes. They look for a hole to stay inside, in the ground, or in a rock or a tree. They do not wake up again until spring comes. Snakes feed on mice, frogs, bird eggs and so on.
Snakes play an important part in nature. We can make useful medicine with them. Without their help, the rodents (啮齿动物) will be out of control. But many of them are in danger of disappearing. Houses and buildings take up the land where snakes live. Many snakes lose their lives in traffic, and people often kill snakes for their skins or meat.

In the past nine years, Li Jin, who was born in Guangxi but raised in Sanya, has made great efforts to protect the waters of Sanya city in Hainan. He is now spreading the knowledge of environmental protection through new media platforms (媒体平台).
Around 2014, he began doing volunteer work to clear rubbish from the beaches and officially registered (注册) as a volunteer in May, 2017. Li Jin immediately took the lead in a cleanup activity on the Sanya River.
In April, 2021, he used his own money to set up a volunteer service center which has 1,170 registered members who take part in activities without asking for payment. So far, he has spent about 3,800 hours on volunteer activities in over 550 events. More than 2,300 people have joined in with his encouragement. They’ve drawn the attention of both the adults (成年人) and the children to the importance of protecting the oceans and beaches. Since it was set up, his center has organized 51 beach-cleaning activities that have seen about 1,800 people join in. In 2021, because of Li’s growing influence in environmental protection circles, the city government invited him to make a number of short videos, in which he uses simple words to explain how to protect the environment. Several of the videos have been watched millions of times.
“My volunteer work would be meaningless if I got paid. But the work itself is of great value. So I will continue doing the environmental protection work,” he said.

【推荐3】Some white cliffs appear in Denizli Province, Turkey. In them are small, bluey-green pools—it looks as if the snow is melting. In fact, those aren’t icy cliffs—they’re terraces of rocks. Because of its appearance, the site is known as Cotton Castle.
Cotton Castle is more than 325 feet high and nearly 9,000 feet long. There are 17 hot springs at the top and the spring water is between 35℃ and 60℃.
The springs are the reason for Cotton Castle’s unusual appearance. Forced by earthquakes, the mineral-rich water comes up from inside the Earth. When the mineral in the water meets air, it forms a jellylike thing as it makes its way down the cliff. Eventually the jelly dries and hardens into white rocks. Some water also collects to create pools. Because the water cools several degrees as it flows into the pools, it’s possible to swim in these natural hot springs.
The process has gone on for tens of thousands of years. Cotton Castle has been a popular attraction since around 200 B.C., when a king founded a town called Hierapolis near the site. People believed the hot springs had healing powers. By the 1970s, Cotton Castle was so popular that hotels were built nearby, even on top of it.
Unfortunately the construction caused parts of Cotton Castle to break off, and heavy foot traffic turned some pools brown. To avoid any future damage, the government listed it as a protected World Heritage Site. The hotels were soon torn down, and now only some pools are open to visitors. With these steps, Cotton Castle will hopefully be around for many years, its ice-like beauty frozen in time.
