2 . People often say that man can change nature or human being is the king of nature. According to the power of nature, however, man cannot live without nature that is offering man with fresh air to breathe, clean water to drink and various food to eat. Besides, animals in nature can help our human in some way.
One man shared his story with some special animals on TikTok.
Ten months ago, Ben started living on his own in Sydney because of the outbreak of the COVID-19. He was feeling very lonely during lockdown（封锁）-he missed his families and friends so much-and that’s when the birds started visiting him.
At first it was just one. He began interested in the regular friend and named it Peter.
“I couldn’t leave for the next hour and a half-I just sat there just let him play. It’s full of life and hope,” Ben told ABC News.
Over the next few months, Peter would come and go. Eventually, Peter started bringing his “girlfriend”.
“That was a turning point,” he said. “And it was strange, because it was when I started to really feel my loneliness in lockdown that the birds were coming more and more often. And whether or not that happened by chance, that’s when I started to take notice of them. They saved me from the deep and helpless loneliness and began to value life.”
Ben posted a video of his new friendship to TikTok where it instantly went viral.

4 . “The pile of ice is so thick; it extends more than 10, 000 feet above the ocean. And if all that ice were to melt and go into the ocean, global sea levels would rise by about 24 feet everywhere around the world,” said Jason Briner, a geologist who studies the ice sheet in Greenland at the University of Buffalo. The ice sheet of the biggest island in the world is melting, and the ice sheet that sits atop it is massive. The ice sheet is melting, of course. But just how much, compared to the past?
Briner’s team did a computer simulation (模拟) of the southwest part of the Greenland ice sheet — which he says is a good indicator for ice melting across the entire ice sheet. The researchers plugged past climate data into that model to “hindcast,” rather than forecast, the past activity of the ice sheet. They then checked the model’s predictions of the past shape and size of the ice sheet by looking at piles of rocks and dirt on Greenland today, which outline the edges of ancient ice. And the simulation was in good agreement with the actual situation.
Using that reconstruction of the ice sheet over time, the team could compare the ice sheet’s historic losses to those happening today under human-caused global warming. And they determined that Greenland is on track to lose more ice this century than during any century in the past 12,000 years — possibly four times as much.
Finally, it’s up to us how much ice actually melts. If the world goes net carbon zero by 2100, for example, Briner says ice loss could stop entirely at the end of the century, according to one model. “That was what kept me from being completely depressed about our study.” Dozens of countries have already announced goals to go net zero by the middle of this century — so far the U. S. is not one of them.

5 . Reducing, reusing, and recycling is a way of life in Sweden. Recycling is required by law and garbage is sorted at home before if goes to a recycling center. Recyclables are sorted into seven categories and recycling stations are within just 300 meters of all residential areas. " Recycling almost everything is a must in Sweden now. It actually feels very uncomfortable when you visit another country and cant find easy ways to recycle, " said Owen Gaffney, an expert at Stockholm Resilience Centre and Future Earth.
But not all of its garbage is recycled. Sweden uses alternatives that include incineratinggarbage to make electricity instead of using fossil fuels（化石燃料）to heat 1.2 million homes. About half of household garbage is sent to one of the 33 waste﹣to﹣heat plants. Sweden is importing garbage from other countries to keep these plants running. Sweden is also a world leader in turning food waste into eco﹣friendly biogas（沼气）. It has made food waste collection compulsory beginning in 2021. There is a food waste biogas plant, which allows biogas to be used to run public buses and to heat apartment buildings.
Sweden now wants to deal with those remaining items that cannot be recycled by using a circular（循环论证的）economy approach. It means that products can be reused and only recycled when absolutely necessary. The Swedish government formed an advisory group to find a way of making this part of its environmental policy.
This will not work effectively unless people are taught to change their behavior. Now the government is reforming its tax code so that people could get cheaper repairs or buy used things. The large Swedish clothing retailer（零售商）H&M operates a recycling program that gives customers discounts when they bring back old clothing.
Sweden is fighting climate change by doing all the right stuff. Waste recycling and the plans to switch to a circular economy will go a long way in reducing its carbon footprint and will help stop global warming.

7 . Scientists say they have found high levels of small plastic particles(颗粒) in Arctic snow. A German-Swiss research team collected snow samples(样本）from the Arctic and other areas. They included northern Germany, the Bavarian and Swiss Alps, and the North Sea island of Heligoland.When the researchers examined the samples in a laboratory, they were surprised to find very high levels of microplastics.
Microplastics are very small pieces of plastic. These plastic particles are generally smaller than 5 millimeters in length. They come from the breakdown of man-made plastic products and industrial waste.
The study found the highest levels of microplastics came from the Bavarian Alps. One snow sample from the area had 154,000 microplastic particles per liter. Samples collected from the Arctic had much lower levels. However, even samples from the Arctic contained up to 14,000 particles per liter.
The study also attempted to explore how some of the material could have been carried in the atmosphere. A limited number of earlier studies did find microplastics in the air of some cities, including Paris, Tehran and Dongguan, China.
Bergmann Melanie co-wrote the report on the new study. She believes the new study clearly shows that “the majority of the microplastic in the snow comes from the air.” The new study suggests that much of the microplastic found in Europe and the Arctic comes from the atmosphere and snow.
While there is growing concern about the effect of microplastics on the environment, scientists are still studying their possible harmful effects on humans and animals. “I hope the new study will lead to more research on this issue. I think microscopic plastic particles should be included in worldwide observations of air pollution levels.We really need to know what effects microplastics have on humans, especially if inhaled with the air that we breathe.” Bergmann said.

8 . I live in a second-floor flat with an ancient tree right on the corner of the house. House and tree have been here, side by side, for well over a century. No one really knows how old the tree is, but it was already there when builders started on the house at the beginning of the 1900s.
It was still rather young and flexible back then, so it easily welcomed the new structure into its path. It bent and adjusted itself to make room, and to find the space to grow big and strong and wise, which means that some hundred years later, the solid, strong branches of the tree reach around two full sides of my home. It’s covered in moss（苔藓）, which is, in turn, crawling with all sorts of insects. I have never seen the insects, by the way, I just know that they’re there because of all the birds trying to pick them out. They are always hopping around, looking for this and that and singing songs.
I feel like I have become part of the ecosystem. When I’m eating breakfast or making dinner in the kitchen, I can look out and see a bird hopping around skillfully, gathering its own meal while I tend to mine. When I’m sitting in the living room, reading or drinking tea, I can suddenly find myself face to face with another bird. We’ll be staring at each other and, after some time, decide we can both carry on with our business, living side by side. Even as I write this—the large windows open to a lovely, soft evening—a white feather comes floating down by my side, probably from one of the resident pigeons.
As I don’t have the luxury of a garden, this tree makes me feel connected to the outdoors. Such is an ancient tree, a tree that is itself home to many other creatures—that feels different. It is as if it has adopted me and made me a part of its world, without ever asking for something in return. But if needs be, I know that it can count on me and I will protect it with all my strength.
