1 . Wild beavers (河狸) are back! Experts say that the wild beaver families are doing well. The beavers are even boosting wildlife and the environment!
Over ten years ago, a family of beavers turned up in a part of the river Otter, in Devon. No one knew exactly where they came from. It was a big surprise wild beavers hadn’t lived in England for around 400 years!
In 2015, the government allowed the beavers to stay there as part of a test. They wanted to see if these animals could be reintroduced to the wild. The test ends in February. Some scientists from the University of Exeter already say the beavers help the wildlife in the area. One scientist called it “an amazing story”.
A lot of this is because of dams (水坝). Beavers build dams along the river. This creates deep pools in the riverbed and slows the water down. Scientists say this is perfect for many different types of plants and animals! Many plants are growing near the beavers. Different types of animals are also becoming more and more in the river. Beavers also help make flooding less, scientists say. The beavers’ dams slow down the speed of the river, especially after heavy rain.
Beavers aren’t the only animals that are being reintroduced to the wild! In 2019, red squirrels were brought back to an area of the Scottish Highlands. Further away, the world's rarest (罕见的) duck, the Madagascar pochard, is making a comeback. It was set free into the wild on the African island in 2019 and is doing well.
Who knows what other animals might be making a comeback?

2 . All living things on Earth need water to live. Yet humans are facing serious water problems. According to the United Nations, today over 663 million people live without a safe water supply close to home.
To remind people of the importance of water, the UN first set up World Water Day in 1993. It is on Mar 22 each year. From Mar 22 to 28 is also the China Water Week. The first year’s theme is “Waste water”. It tried to call people to reuse waste water instead of wasting it.
In Australia people make good use of waste water. Most Australians have a grass lawn around their home instead of washing the car in the street. Many of them wash it on the lawn to keep the grass longer so that it covers the ground and reduce evaporation.
Rainwater may seem useless to you. But you can also reuse it. People in Germany collect rainwater to wash their toilets. Most houses in the country that are built in the last few years have rainwater collection devices (设备). Rainwater is collected from the root, and then linked to the toilet. But if you don’t have the device just put a bucket (桶) under your roof when it rains.
Water makes up 71 percent of Earth’s surface. But we can only use a very small part of it. Only about 3 percent of the world’s water is fresh water. It’s in lakes, rivers and underground.
Over 80 percent of the w
aste water in the world goes back into the nature. It has not been cleaned and pollutes the rivers and lakes. Unsafe water makes around 842,000 people die each year.
By 2030, about half of the world’s population could be facing water problem. By 2050, as many as seven billion people across the world could not have enough water supplies. The world’s population might be 9.3 billion by then.

I never grasped the importance of conserving and protecting nature and wildlife, but five months was all it took to turn my indifference into a passion that has changed the track of my life.
Early last year, I was lost and troubled by an anxiety that crippled (削弱) my ability to do anything, even those I loved. I felt like a storm cloud hung over me. For almost a year I struggled on, constantly staring at this wall that faced me. My pursuit of perfection was the main root of this: I wanted to be the best at whatever I did, which obviously in life is not possible. My perfectionism has always been with me. My time in a small junior school made it easy for me to rise to the top. Upon entering a bigger senior school, though, my pursuit of perfection was far from accessible. Perfectionism in small amounts is brilliant, however in overwhelming doses it can be damaging.
One day, I attended a presentation by wildlife conservationist Grant Brown at my school. His presentation not only awed and inspired me, but also helped emerge an inner desire to make a difference in the world. Luckily, as a member of the Environmental Society, I was invited to join a pre-presentation dinner with him and that smaller setting allowed me to slowly build up my courage to speak one-on-one with him—an idea that had seemed completely impossible. This first contact was where my story began.
First, an application to join the Youth For Our Planet and UK Youth For Nature groups was sent around through my high school. I decided to submit my application, and soon I found myself a part of a growing global team of young people working to protect nature and creating climate solutions. Later, Brown invited me to attend the World Youth Wildlife Conference.

Spring has come with all its beauty! Trees have turned green or flowers can be seeing everywhere. Last Friday, my friends and me went on a spring outing. It was such a great fun! We cycled along the streams and down the paths. It didn’t take us long to get the foot of the mountain, that we left our bikes. Then we begin hiking. As we reached the top of the mountain, we were shocking to see many plastic bottle and food bags here and there. All of us started to collect the rubbish and then took it down the mountain. We felt happily to have done our part for the environment.
7 . According to the World Food Program, one third of the food of the world is lost or wasted. It’s up to some 1.3 billion tons every year, worth about $1 trillion. Moreover, a report in 2021 Sugests that 8 to10 percent of global greenhouse gas emissions (排放) are associated with wasting food.
“For our parents and the older generations,‘clearing your plate’ is more about saving some food for a rainy day.”Liu Jichen, founder and CEO of Clear Plate, an anti-food wasting program, told us.
The idea for Clear Plate came to Liu after one dinner at a restaurant in late 2017. The customers who finished all the food they’d ordered would be given a card, and then they could exchange their cards for rewards. “Yet it was limited to one restaurant’s actions, so I thought, why not try it on a larger scale (规模)? And how?” Liu wondered. And then he teamed up with some of his friends,founded a startup and developed the Clear Plate applet.
“The Clear Plate team is trying to deal with the issue (问题) of food waste. After a meal, users of WeChat take photos of their clean plates, post these on WeChat, collect points, and then exchange their points for gifts or charity donations,” Liu explained.
Starting in 2018, Clear Plate has now more than 4.3 million users with about 45 million participations in anti-food wasting actions, reducing food waste by 1,700 tons and carbon emissions by 6,600 tons. Liu’s determination represents a small change of the Chinese lifestyle and more people are turning toward a healthier, greener and more low-carbon lifestyle.

10 . Today, you can buy a pair of sneakers (运动鞋) partially made from carbon dioxide pulled out of the atmosphere. But measuring the carbon-reduction benefits of making that pair of sneakers with carbon dioxide is complex. There’s the carbon dioxide that stayed in the ground, a definite carbon reduction. But what about the energy cost of cooling the carbon dioxide into liquid form and transporting it to a production facility? And what about when your kid outgrows the shoes in six months and they can’t be recycled into a new product because those systems aren’t in place yet?
Researchers are trying to help companies figure out how to account for each step in a product’s life.
As companies try to reduce their carbon footprint, many are doing life cycle assessments to measure the full carbon cost of products, from the obtaining of materials to energy use in manufacturing, from product transport to users’ behavior and end-of-life disposal (处理). It’s an impressively complex measurement, but such bean-counting is needed to hold the planet to a livable temperature, says low-carbon systems expert Andrea Ramirez Ramirez of the Delft University of Technology in the Netherlands.
Carbon use can be reduced at many points along the production chain—by using renewable energy in the manufacturing process, for instance, or by adding atmospheric carbon dioxide to the product. But if other points along the chain like transporting consume more energy or give off more carbon dioxide, Andrea notes, the final record may show a decrease rather than a reduction. A product is carbon-reduction only when its production actually removes carbon from the environment, temporarily or permanently.
In the rush to create products that can fight climate change, however, some companies have been charged with “greenwashing”—making products appear more environmentally friendly than they really are. Examples include labeling (用标签表明) plastic garbage bags as recyclable when their whole purpose is to be thrown away; using labels such as “eco-friendly” or “100% Natural” without official certification; and claiming a better carbon footprint without acknowledging the existence of even better choices.
