1 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.
As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

2 . When I give public lectures about the climate crisis, the most common question people ask is: “Are you an optimist?” My answer is yes. The second most common question is: “What can I, personally, do?”
That’s a tough one. About half of all greenhouse gas emissions come from electricity generation and industrial fossil-fuel use. Some people have argued that calls for individual action actually distract us from company’s responsibility. Oil giant BP promoted the idea of a carbon footprint, moving attention to its customers who, it suggests, should take personal responsibility by lowering their carbon footprints. One study found that focusing on personal activity will ruin support for more effective policy initiatives (提案) such as a carbon tax.
Another problem with personal behavior is that people do not like to be told what to do. As former congressperson (国会议员) Bob Inglis of South Carolina said, people think, “You’re saying that I shouldn’t have this house in a suburb? I shouldn’t be driving this car.”
Cutting meat consumption (消耗) is a powerful and personal thing most Americans can do to deal with the climate crisis, and they can do it immediately. About 40 percent of greenhouse gases come from agriculture, deforestation and other land-use changes. Meat—particularly beef—drives climate change in two ways: first, through cows’ emission of methane(甲烷), and second, by destroying forests as land areas as required to the cows to live on. Despite the economic slowdown caused by the COVID 19, atmospheric greenhouse gas levels continued to rise in 2020, in large part because of emissions increase in the Amazon as rain forests were changed into land for cattle to satisfy the global demand for beef. By eating less beef, we can start to reduce that demand.
You do not have to become a vegan (素食主义者) to do this. Cutting back on red meat also has the added benefit of being good for your health. While I wouldn’t advise governments to order people to stop eating hamburgers, if anyone asks, “What can I do?” a simple and accurate answer is: “Eat less meat. It’s in your control, and you can begin right now. It benefits both you and the planet.”

The Great Wall’s
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.

9 . Carbon dioxide emissions from transportation are now thought as the top source of green-house gases. One of the most effective ways to reduce your carbon footprint is to reconsider how much, and how often, you travel.
Going car free for a year could save about 2. 6 tons of carbon dioxide, according to a study from the University of British Columbia. How can you stop using a car? Try taking a train, bus or better yet, riding a bike.
But let’s be realistic. You will likely need to use a car this year. So, when you do, here are some tips to make your trip more climate-friendly. Driving efficiently can help to reduce emissions. Go easy on the gas and brakes and drive like you have an egg under your foot. Regularly service your car to keep it more efficient. Keeping your tires pumped correctly can re-duce emissions. Low tire pressure will hurt your fuel economy. Air conditioning and frequent city driving can make emissions go up. So cut down on these as often as possible. Use cruise control (定速巡航) on long drives-in most cases, this can help to save gas. Don’t weigh your car down with extra things that you don’t need on your trip.
Fly often? Taking one fewer long round-trip flight could reduce your personal carbon footprint significantly. If you use public transportation often and fly less, your carbon foot-print might still be relatively sustainable, but if you drive and fly a lot, your emissions will be sigher. If you can’t avoid flying, you can offset them by donating money to sustainable proacts, such as supplying efficient stoves to rural homes, or projects which help farmers deal with crop waste environmentally.

10 . The world’s first 3D-printed wood log hive (蜂箱) is a new project developed by the Lacrima Foundation in Edinburgh to reduce the troubling decline of honey bee populations around the world.
The Lacrima Foundation is a charity that is “committed to the conservation and protection of one of the Earth’s most important inhabitant.” The charity teamed up with beekeepers in Europe to work towards a rewilding approach that would offer bees a natural nest habitat and, in turn, create resilience (复原力) among bee communities.
Honey bees are one of the most important pollinators (授粉者), and although they may seem small and insignificant, they are vital for the production of our food — we couldn’t eat without them! However, in recent years, bee populations have been severely impacted by the growing climate emergency and our intensive agriculture practices, including the overuse of pesticides.
With help from local partners, the Foundation created 3D-printed wood log hives, which allow the bees to live in an undisturbed ecosystem where they can carry out their lives. They install these hives in high sections of tree trunks to model natural conditions for the big honey bee populations.
Vince Moucha, chairman of the Lacrima Foundation, said, “Even though there are other people and organisations working in the field of natural beekeeping, the impact, progress and scope of these projects is minimal and slow, due to limited access to resources and clear vision. I am driven by responsibility and decided to act on it due to the urgency and importance of this matter.”
The Foundation will continue to work with beekeepers in the UK, Europe, and the United States to help our bee populations survive and thrive for them and us! Check out the Lacrima Foundation, where you can see their mission and donate to the cause and even get a honey bee gift bracelet in return.
