2 . Growing up in Louisiana, across the Mississippi River from New Orleans, Barry Guillot loved exploring the wetlands with his friends when he was a child. However, as he grew older, a growing concern about the disappearance of wetlands took root. “Imagine if the New Orleans Saints, our football team, were playing on a field that was actually wetlands,” Barry says. “By halftime, that football field would be gone.”
In 1988, Barry became a middle school science teacher. With the intention of bringing home to his kids the importance of wetlands, he founded the LaBranche Wetland Watchers Service-Learning Project, “adopting” a small part of LaBranche Wetlands near their school.
Wetland Watchers activities are tied to academic subjects. Water-quality monitoring, for example, teaches students to use graphs to compare data from different time periods — part of the math curriculum. After Hurricane Katrina, the salinity (amount of salt in the water) was four times as high as before. Students made graphs to show that. As part of English composition, they wrote about seeing jellyfish (水母) , which had never come that far before because jellyfish live only in salty water.
“We obtained more than we would just sitting behind a desk with a book, because you’re out there and you’re getting all wet and muddy and having fun as you learn,” says Kurt, a seventh grader.
Barry is very proud of his students. “It’s amazing what middle school kids can accomplish when they get the chance,” he says. One of his seventh graders wrote, “If the animals and plants could talk, I think they would say we’re their heroes. That’s the way I feel when we do our work in the wetlands.”

3 . The temperature was rising to 90 degrees on Tuesday in the hills of the Delaware Water Gap National Recreational Area, when Lexie Daniel and her friends saw a heroic act of kindness to save a dog’s life.
Lexie and her fellow hikers met a man whose dog was seriously overheated. Even though they donated (捐赠) their water, they were afraid it wouldn’t be enough to save the pup, after seeing how much the dog was already struggling.
“The owner brought along a huge jug, but no water seemed to be helping,” Lexie told GNN.
Too tired to carry the dog himself, the loving owner called the park rangers as soon as possible. Supervisory Park Ranger Kris Salapek soon found them on the trail (追踪). Kris then lifted the huge dog onto his shoulders and carried him down the mountain. “It was a long distance-a couple miles down a difficult rocky path,” says Lexie.
When they reached the stream, Kris laid him in the water as he knelt beside him and poured water on him. The ranger then picked him back up over his shoulders and walked all the way back down to the street for about an hour.
Lexie’s cousin Tori Matyola said, “The owner hiked down ahead of the ranger so that once he got down the mountain he had the car ready to take him straight to the vet. The dog was looking a little better by the time he got to the car and picking up his head.”
When she got home, Lexie, a pediatric (小儿科的) nurse from Hackettstown, New Jersey, posted the good deed on Facebook and it went viral with 35,000 people sharing the post and showing admiration for the ranger.
“This is a HERO,” Lexie wrote. “We are so lucky to have rangers like this who put animals before themselves. This ranger deserves recognition and a standing ovation (列队鼓掌) for his bravery, selflessness, and strength.”

4 . In Canada, you can find dogs, cats, horses, etc. in almost every family. These are their pets. People love these pets and have them as their good friends.
Before they keep them in their houses, they take them to animal hospitals to give them injections (注射) so that they won’t carry disease. They have special animal food stores, though they can get animal food in almost every kind of store. Some people spend around two hundred Canadian dollars a month on animal food. When you visit people’s houses, they would be very glad to show you their pets and they are very proud of them. You will also find that almost every family has a bird feeder in their garden. All kinds of birds are welcomed to come and have a good meal. They are free to come and go and nobody is allowed to kill any animal in Canada. They have a law against killing wild animals. If you killed an animal, you would be punished. If an animal happened to get run over by a car, people would be very sad.
People in Canada have many reasons to like animals. One of them might be: Their family ties are not as close as ours. When children grow up, they leave their parents and start their own life. Then the old will feel lonely. But pets can solve this problem. They can be good friends and never leave them alone.

5 . Scientists say baby sharks are at risk of being born smaller and without the energy they need to survive because of warming oceans from climate change.
Scientists studied epaulette sharks, which live off Australia and New Guinea. They found that warmer conditions expedite the sharks’ growing process. That meant the sharks were born earlier and very tired. The findings could be used in the study of other sharks, including those that give birth to live young.
The scientists studied 27 sharks. Some were raised in average summer water temperatures, about27 degrees Celsius. Others were raised in higher temperatures around 29 degrees Celsius and 31 degrees Celsius. They found that the sharks raised in the warmest temperatures weighed much less than those raised in average temperatures. They also showed reduced energy levels.
Epaulette sharks can grow to a length of about one meter. Their name comes from large spots on their bodies that look like decorations on some military clothing.
One study this year found that worldwide numbers of oceanic sharks and rays dropped more than70 percent between 1970 and 2018. Overfishing is a main concern, while climate change and pollution also threaten sharks.
Carolyn Wheeler is a doctoral student at the University of Massachusetts Boston and with the ARC Centre of Excellence for Coral Reef Studies at James Cook University in Australia. She is the lead author of the epaulette shark study. She said that while all the sharks survived, those raised in warmer temperatures were not strong enough to survive for long in the wild.
She added that if the sharks are born smaller than usual, they are probably going to have to start looking for food sooner, and they’re going to have less time to adjust to their surroundings.
The study should serve as a warning to ocean governing agencies that careful management is needed to prevent the loss of more sharks.

6 . From Jilly Cooper to Winston Clurehill, horse riders have long supported the emotional benefit of the human-horse bond. Hernan Melville, the author of Moby Dick, once argued: “No philosophers so thoroughly comprehend us as dogs and horses.”
When it comes to dogs, we have no doubt about it. But horses can tell when a human being is feeling unhappy, a study has found, although whether or not they care remains an open question.
The latest study, published in the journal Animal Cognition, sought to correct this. The question the researchers wanted to answer was; do horses understand a range of human emotions? To investigate this, they employed a technique often employed in studying baby cognition (认知); they showed the horses something that made no sense, and watched to see whether it puzzled them. One after another, the scientists put 28 horses in a room. Each horse was shown two pictures of the same person at the same time. In one picture the person had a happy face, in the other the person had a long face. At the same time they heard either a happy or sad voice.
From a human perspective, only one of the pictures made sense — the one with a voice that corresponded to the image. The other was “incongruent (不一致的)”. Were the horses similarly confused? It appears they were. What the scientists found was that on average the first time the horses saw the incongruent image, they spent longer looking at it.
Oceane Liehrmann, from the University of Turku in Finland, said this implied a level of emotional and cognitive complexity that we may not always credit to horses.
We don’t know whether horses themselves understand what it is to be sad, or experience the emotion. What the research suggested was that, however, it is possible they learn that it means something for a human — and that when we are sad they expect what we say to match how we look.

7 . Four Beautiful National Parks in New Zealand
Fiordland National Park
With over three million acres, the Fiordland National Park is the largest in New Zealand. It is also one of the most popular tourist attractions, drawing hundreds of thousands of visitors yearly to its dramatic landscape. When visiting, you will find beautiful fiords (峡湾), ancient rainforests, shining lakes, waterfalls, and snow-capped peaks.
Abel Tasman National Park
Located on the north end of the South Island is Abel Tasman National Purk, named after the first European explorer to find New Zealand. At nearly 60,000 acres, it is the smallest national park in the country, but it offers the perfect mix of relaxation and adventure. For instance, the park features sandy beaches, clear streams, forested hills, and mossy valleys. The best way to experience the area is by hiking, camping, kayaking, sailing and swimming.
Arthur’s Pass National Park
Also on New Zealand’s South Island is Arthur’s Pass National Park, featuring primarily mountainous terrain (地形). Arthur’s Pass includes the heart of the Southern Alps and consists of high, rough mountains, steep gorges and wide rivers. Because the area is not as developed as other parks and requires visitors to have a knowledge of route-finding and river-crossing, it is not typically an area for inexperienced recreationists.
Tongariro National Park
Tongariro was the 6th national park established in the world and the oldest in New Zealand. It’s been open to the public since 1887 and is the perfect destination for thrill-seekers and those who appreciate mother nature. The park contains three active volcanoes and features world-famous crossings for some of the best hiking and skiing in the world.

8 . In a world-record effort to help save a valuable sea creature, Australian scientists have released hundreds of baby seahorses into the wild. The tiny seahorses are endangered, and the scientists hope the new seahorses will help their numbers grow.
Seahorses get their name because they look a bit like horses. They aren’t great swimmers, even though they’re fish. They often use their tails to hold onto something in the water. They mostly live in warm, shallow waters around the world. They are often found in coral reefs, in beds of seagrass, and areas where rivers empty into the sea. Seahorses form an important part of the ocean’s food chain. They eat tiny sea creatures and are eaten by bigger sea animals.
Many kinds of seahorses are often threatened by the human actions. Sometimes they’re caught and sold as pets. They are also caught by accident when people are trying to catch other fish.
To begin the project, scientists collected three pregnant seahorses in January. Those seahorses were brought back to the aquarium (水族馆) in Sydney. After the babies were born, the scientists kept them there for five months, feeding the baby seahorses shrimps (小虾) to help them grow strong. Scientist Mitchell Brennan says, “They don’t have a stomach, so they have to eat constantly.”
About a month before the young seahorses were released, the scientists created eight underwater “hotels” for them. The hotels look like cages, providing a safe place for the seahorses to develop. Putting the hotels into the sea early allowed the cages to be covered with small sea life that can help provide food for the seahorses.
This is the fifth time the scientists have released seahorses into the area, and this time was a record. Around 380 seahorses were released. The researchers put tiny tags (标记) under the skin of many of the seahorses to help track them in the future.

9 . Lots of animals play. But the behavior is best known in mammals (哺乳动物) and birds. Now the scientists at London’s Queen Mary University report that bumblebees (大黄蜂) know the same thing. But before this, there were no reports of insects playing.
Dr. Lars Chittka began to wonder if bumblebees played during an earlier test. In that test, Chittka guided bumblebees to move balls into a goal for food. He noticed that some bees were rolling (滚动) balls even when they weren’t given food. He wondered if they were playing.
To test the idea, the scientists at his lab set up a new test. First, they numbered 45 young bumblebees between one and 23 days old. The numbers let them follow bumblebees’ behavior. Then, they set up a clear pathway from the bumblebees’ home to a feeding area. On either side of the open pathway, the researchers placed small colored wooden balls. On one side of the path, the balls couldn’t move. On the other side, the balls could roll around. For three hours a day, over 18 days, the scientists opened the pathway between the home and the feeding area. The bumblebees never had to leave the pathway to find food, but they left anyway. They weren’t interested in the side where the balls didn’t move, but they made lots of visits to the side with the rolling balls.
Catching the balls with their legs, the bees would move their wings to pull on the balls, causing them to roll. The 45 numbered bumblebees did this 910 times during the test. Though some only did it once, others did it a lot. The younger ones liked to spend more time rolling balls while the older ones showed less interest in it. One bee was recorded rolling balls 44 times in a single day. One was seen rolling balls 117 times over the whole test.
The test raises important questions about how the insects’ minds work and whether they have feelings.
