2 . The sighting of a new family of gray wolves in Oregon’s Cascade mountains has given wildlife protectors hope that the recovery of the endangered animal in the state is on the way. The state’s fish and wildlife department (部门) said a group of two adults and two babies was recorded by a track camera in August.
The wolves were found in the area of Warm Springs and officials have named it AKW — a new area of known wolf activity. If the group still has all four members surviving at the end of the year, the animals will be known as the Warm Springs group, the state’s third one in the northern Cascades. “Wolves will move to different places, but when we have resident wolves, like we know they’re sticking in that area, that’s when we create an AKWA to make sure the wolf count rise constantly.” the agency’s worker, Michelle Dennehy, told USA Today.
Many years of hunting of gray wolves almost made them die out across the nearby 48 US states by the middle of the last century. In Oregon at the end of 2009 only 14 wolves were known to exist. With protections from the Endangered Animals Act beginning in 1974, numbers have risen slowly since, to 175 in Oregon by the end of last year, living in more than 35 groups.
“I hope this will be an exciting new chapter in the story of wolf recovery in the state. Having more wolves establish families in western Oregon will be important for the long-term survival of these beautiful animals,” Amaroq Weiss, senior wolf protector at the Center for Biological Diversity, said in a statement.

4 . Buying furniture is easier than ever. You can even order a new table and chairs online without ever leaving home. But did you ever think about how furniture is made? The process begins with trees but now researchers have found a better way: growing it in a lab instead of a forest. Instead of cutting down trees and adding to deforestation, Velasquez-Garcia said, “If you want a table, then you should just grow a table.”
The research group found a way to actually grow plant tissue (组织) — wood and fiber — in a lab that is similar to the way cultured meat is grown. While there is still a long way to go to actually grow a table, the team was able to grow structures from cells from zinnia leaves.
Making furniture and other items from biomaterials could eliminate cutting down trees in forests. “The way we get these materials hasn’t changed in centuries and is very inefficient,” said Velasquez-Garcia. “This is a real chance to avoid all that inefficiency.”
There are other benefits to using lab wood too. Lab grown wood can be handled to take on any shape — like 3 D printing — so it may be possible to build a table without glue or screwing parts together.
Beckwith, a mechanical engineering PhD student, was inspired by a visit to a farm to try to make land-use more efficient and environmentally sound. “That got me thinking: Can we be more strategic (战略上的) about what we’re getting out of our process? Can we get more yield for our inputs?” she told MIT News. “I wanted to find a more efficient way to use land and resources so that we could let more farmlands remain wild, or to remain lower production but allow for greater biodiversity.”
Today, the two largest uses of trees are to make wood products and paper. When new biomaterials become readily available, forests will lose their economic value and will be preserved for their environmental, health, and recreational value. These researchers, like Velasquez-Garcia, are speaking for the trees.

8 . Even if you live a green lifestyle at home,it's possible to ignore that travels may be harmful to the environment. Here are some steps you can take to reduce the harm that comes from traveling.
Make clear the environmental challenges. Every country has environmental challenges to deal with. For some,it is plastic bags,for others the amount of energy used on air conditioning or heating. Make sure you know them and act responsibly. Use water wisely,for example,when you are in dry countries.
A.Be as green as you are at home. |
B.Find eco–friendly accommodation. |
C.Eat locally grown foods as much as possible. |
D.Choose a green means of transportation. |
A Rubbish Collector's Work Is Never Done
Brian Kane was a rubbish collector in Denver, Colorado. Eight hours a day, five days a week, fifty weeks a year, he rode on the back of a garbage truck. At each stop, he would jog to the back of buildings, then drag heavy rubbish cans to the truck. Brian never complained.
Brian saw these hardships as opportunities to become strong and fit. His job was a training ground for his lifelong dream: to climb Mount Qomolangma. On his thirtieth birthday, Brian took a leave from his job and flew to Nepal to begin the long, difficult journey up Mount Qomolangma.
Brian first climbed to a base camp. He planned to bring three oxygen containers with him to the top. At 29, 028 feet, it would be hard to survive without extra oxygen. Over the next two months, Brian climbed to 26, 000 feet, to Camp Four—the last place to rest below the top of the mountain. But when Brian saw this camp, he fell to his knees. “Rubbish!” he cried. Nearly a thousand empty oxygen containers littered the camp area. Humans had turned this beautiful, far-away place into a big rubbish pile. Brian was very sad. But with a strong determination he continued to follow his dream. Two days later he stood proudly on the top of Mount Qomolangma. He had reached the “roof of the world!”
Two days after this great achievement, Brian put a dozen empty oxygen containers in his pack and headed down the mountain He smiled to himself as he realized that the work of a rubbish collector is great and never done.

10 . The world is going through a basic transformation,which is changing the way we live, work and think. The Fourth Industrial Revolution is bringing dramatic change and giving rise to a future filled with exciting opportunities and new challenges. Together, governments and businesses must find solutions to society's most pressing needs—from creating a carbon-free economy to tackling population growth and urbanization.
In any period of rapid change there is a trend to look for a simple method,to greet the new things and replace the old way of doing things. But a closer look at the facts tells a different story. Complex problems require many solutions working in harmony to enable positive change.
The challenge for scientists and engineers is to provide solutions in fact, data and today's realities. And while technologies offer new tools to help uncover solutions, the process also requires hard work, imagination and lots of improvement.
Success rests on performing practical, realistic, long- term solutions that make the world cleaner, safer and more sustainable(可持续的).
The environment is a case in point. Much of the public debate has centered on the central role of renewable power sources in realizing a low-carbon energy future. While the industry is fully behind developing renewables, today we understand that a low or zero-carbon future depends on adopting a multifaceted approach.
We cannot control sunshine levels or decide when the wind blows, which means solar power and wind power generators will produce too much or too little energy at times. The transition to renewables needs to take account of serious considerations.
Batteries have been much discussed as a means of storing extra energy, but there are other choices. Power-to- X technologies enable spare energy created by renewables to be stored and redistributed when and where it is needed.
