2 . Have you ever imagined being able to communicate with your pet at home and have it understand everything you say? It sounds too good to be true, but scientists have started using artificial intelligence (AI) to help communicate with animals.
Professor Karen Bakker—who is the author of a book called The Sounds of Life: How Digital Technology Is Bringing Us Closer to the Worlds of Animals and Plants—said that AI is already helping humans communicate with bats and honeybees and this could change what we know about nature and our non-human relationships.
Scientists have worked out how bats speak to each other to argue over food and how mother bats communicate with their young.
Professor Bakker explained how researcher Yossi Yovel had used recordings and AI to understand bats.
“Bats argue over food; they actually distinguish between genders when they communicate with one another; they have individual names, or ‘signature calls’,” she said.
“Mother bats speak to their babies in a kind of ‘motherese’.
Bats learn to ‘speak’ with signals from their mothers.
But while human mothers raise the pitch(音高) of their voices when talking to babies，mother bats lower the pitch.
She said it was a great example of how animal patterns could be revealed using sensors and microphones that would otherwise never be heard with the human ear.
AI makes this possible because a computer can be trained to listen like a bat.
With honeybees, the computer combines listening with vision of the bees’ body movements to understand what they are communicating. Researchers now know how be essay things such as “hush” or “stop”.
Researcher Tim Landgraf even created a robot honeybee that entered a hive(蜂房) and was able to communicate with other bees when it wanted them to stop doing something or fly.

4 . WHY SHENNONGJIA?
As we know, in 2016, Shennongjia made it on to the UNESCO World Heritage List. But there are so many important places not yet on this list. So you might ask: why Shennongjia?
UNESCO awarded Shennongjia this status because it meets two criteria required by the list. It contains a naturally-balanced environment that allows the many and various species to live and prosper. It is also one of the rare locations in the world where scientists can observe in real time the ecological and biological processes that occur as the plants and animals develop and evolve.
For the first criterion, Shennongjia is apparently one of the most “complete” natural areas in the world. The region rises from about 400 metres to over 3, 000 metres above sealevel, giving it the name the “Roof of Central China”.
For the second criterion, we can see that Shennongjia has incredible biodiversity. Look at this slide. According to official statistics, over 3, 000 plant species have been recorded there. This represents more than ten percent of China’s total floral richness.
It is a challenge to look after so many species. In winter, scientists brave heavy snow and freezing temperatures to supply food to the Golden Snub-nosed Monkey. Thanks to their efforts, the monkey’s population has doubled since the 1980s.Their number reached over 1, 300 in 2015 and continues to grow.
But the most impressive aspect of Shennongjia is the local people, who take things from nature without causing damage. I visited a local village which is known for its home-made honey. What is special about the honey is that it is produced by the earliest species of Chinese bee. All of this explains why Shennongjia earned—and deserves—its place on the UNESCO World Heritage List, as well as highlighting how understanding, awareness and hard work have contributed towards protecting a unique and wonderful part of our natural world.

7 . Margot doesn’t have a garbage can. It doesn’t need one because Margot simply doesn’t cause anything to get thrown away. The restaurant doesn’t allow any type of single use plastic. Margot, which opened last year, is one of the small but growing restaurants around the world aiming to avoid not only food leftovers, but also any garbage.
“Food waste has been increasing as an issue for restaurants over the last 10 years,” says Calvin Brown. He runs the Sustainable Restaurant Association. Based in the United Kingdom, the organization helps food business become more environmentally responsible. He says that food waste contributes to releasing the greenhouse gas, so there is strong motivation to reduce waste and help the environment.
In the USA, food waste and packing account for nearly half of the material sent to landfills. Restaurants from McDonald’s to Starbucks are addressing this issue with “no straw Mondays” and limits on single-serving plastic, but a handful of restaurateurs are trying to get rid of rubbish entirely. There’s also economic case to be made for waste reduction. One study shows that restaurants save seven dollars for every dollar invested in anti- waste methods.
Avoiding food waste is the first and perhaps most obvious challenge for sustainable restaurants. Doug McMaster, chef at Silo in London, only serves a set menu. This removes the worry that one particular item won’t sell well, and will spoil in the refrigerator. Compost (堆肥) is a necessity as well. Nolla (meaning “zero” in Finnish) in Helsinki, Finland is giving compost to its suppliers as well as its diners. Nolla also has food- tracking software more commonly used among corporate food service companies to keep track of what sells and what rots.
Sometimes restaurants call themselves environmentally friendly, but they might just be using the label. Calvin offers some pointers on what to look for to make sure a restaurant is truly committed to sustainability.

8 . Beavers (海狸) and their dams can positively impact essentially any environment they’re placed in, even the extreme heat of the Moab Desert in Utah. And that is what a university researcher has founded. Looking for solutions to drought and wildfires, a Utah State University student Emma Doden began relocating (搬迁) beavers caught in other parts of the state into small, struggling waterways around the Price and San Rafael rivers.
Studies have shown that beaver dams can vastly improve the quality of wetlands and streams leading to better animal life and improved river health. It was for this service that the “ecosystem engineer” was targeted by Doden as a potential rescuer, even if the idea relocating beavers to the desert caused a few raised eyebrows. “We believed the system could support a lot more beavers”, Doden said, “and we wanted to supplement it with beavers.”
“Beaver dams are gaining popularity as a low-tech, low-cost strategy to build climate resiliency (还原能力) at the landscape scale,” says one study. “They slow and store water that can be accessed by plants during dry periods, effectively protecting riverside ecosystems from droughts.” Another study found that the ponds which are created on the dammed side of the beaver homes can store huge amounts of sediment (沉淀物) then distribute it more safely around the river ecosystem.
This is the case, the study found, both in entirely wild areas with no human activities and those near to intense agricultural regions, meaning that no matter the conditions of sedimentation, beaver dams can help keep waterways clearer. Doden’s university has a program for catching beavers and relocating them to the desert, where they will build dams to provide these benefits. “The eventual goal is to get them to build dams,” she said. “The dams are what are going to increase habitat complexity and restore water.”

9 . The Australian Koala Foundation says Australia has lost about 30 percent of its koalas over the past three years. The non—profit group says drought, wildfires and development projects played a part in the drop in the koala population. They are asking the government to do more to protect the creature’s environment.
The group said the koala population has dropped to less than 58,000 this year from more than 80,000 in 2018. The biggest decrease(减少) was in the state of New South Wales, where the numbers have dropped by 41 percent. Deborah Tabart leads the Australian Koala Foundation. She called the drop quite huge. Only one area in the study was estimated(预估) to have more than 5,000 koalas. Some areas were estimated to have as few as five or ten.
Tabart said, “What we’re concerned about are places like western New South Wales where the drought over the last ten years has just had this cumulative(积累) effect, river systems completely dry for years, and red gum plants, which are the lifeblood of koalas, are dead.” The loss in New South Wales likely sped up after large forest areas were destroyed by wildfires in late 2019 and early 2020. But some of those areas already had no koalas.
Tabart said the country needs a koala protection law. Land clearing by property developers and road builders has also destroyed the koala’s environment. “I think everyone gets it that we’ve got to change. But it bulldozers (推土机) keep working, then I really fear for the koalas,” Tabart said.
