Most of us spend our lives seeking the natural world. We go fishing, sit in the garden, have a picnic, live in the suburbs or go to the seaside. The most popular leisure activity in Britain is going for a walk. When joggers jog, they don't run the streets. Every one of them tend to go to the park or the river.

    But despite this, our children are growing up nature­deprived(剥夺). I spent my boyhood climbing trees. These days, children are robbed of these ancient freedoms, due to problems like crime, traffic, the loss of the open spaces and strange new ideas about what is best for children, that is to say, things that can be bought, rather than things that can be found.

    The truth is to be found elsewhere. A study in the US: families had moved to better housing and the children were assessed for ADHD—attention deficit hyperactivity disorder(多动症). Those whose accommodation had more natural views showed an improvement of 19%; those who had the same improvement in material surroundings but no nice view improved just 4%.

    ADHD is one of the great problems of modern childhood. One study after another indicates that contact with nature gives huge benefits to ADHD children. However, we spend money on drugs rather than on green places.

    The life of old people is measurably better when they have access to nature. The increasing concern for the growing population of old people is in quality rather than quantity of years. And study after study finds that a garden is the single most important thing in finding that quality. Even problems with crime and aggressive behaviour are reduced when there is contact with the natural world.

    We need the wild world. It is essential to our well­being, our health and our happiness.

    “Sesame Street” has been called “the longest street in the world”. That is because the television program by that name can now be seen in so many parts of the world. That program became one of American's exports soon after it went on the air in New York in 1969.

    In the United States more than six million children watch the program regularly. The viewers include more than half the nation's pre-school children, from every kind of economic, racial, and geographical group.

    Although some educators object to certain elements in the program, parents praise it highly. Many teachers also consider it a great help, though some teachers find that problems arise when first graders who have learned from “Sesame Street” are in the same class with children who have not watched the program.

    Tests have shown that children from all racial, geographical, and economic backgrounds have benefited from watching it. Those who watch it five times a week learn more than occasional（偶然的）viewers. In the US the program is shown at different hours during the week in order to increase the number of children who can watch it regularly.

    The programs all use songs, stories, jokes, and pictures to give children a basic understanding of numbers, letters and human relationships. But there are some differences. For example, the Spanish program, produced in Mexico City, devotes more time to teaching whole words than to teaching separate letters.

    Why has “Sesame Street” been so much more successful than other children's shows? Many reasons have been suggested. People mention the educational theories（理论）of its creators, the support by the government and private（私人的）businesses, and the skillful use of a variety of TV tricks. Perhaps an equally important reason is that mothers watch it along with their children. This is partly because famous adult stars often appear on it. But the best reason for the success of the program may be that it makes every child watching feel able to learn. The child finds himself learning, and he wants to learn more.

    In recent years, much of the sea ice that polar bears use as a hunting platform for seal meals has melted, forcing some bears — particularly young males — farther north or onto land, where they are not as skilled at hunting. When stuck on land for months, a polar bear typically is forced to survive on its own fat reserves.

    The bears were listed earlier this year as a threatened species under the U. S. Endangered Species Act as populations have declined. Meanwhile, snow geese are booming near the western Hudson Bay, and there are in fact too many of them. Their eggs can be a good food source. The geese nest on tundra (冻原；苔原) that some bears have retreated to.

    "Over 40 years, six subadult (接近成年的) male bears were seen among snow goose nests, and four of them were sighted after the year 2000," says Robert Rockwell. "I've seen a subadult male eat goose eggs whole or press its nose against the shell, break it, and eat the contents."

    Ice is melting, on average, 0.72 days earlier each year in the region studied. Snow geese are hatching eggs about 0.16 days sooner each year, according to Rockwell and his graduate student Linda Gormezano. Current trends indicate that the arrival of polar bears will correspond to the average hatching period in 3.6 years, and egg consumption could become a viable option, which the researcher concluded in a statement released today.

    A polar bear, the largest land carnivore (食肉动物), would need to consume the eggs of 43 nests to replace the energy gained from the average day of hunting seals, but Rockwell and his colleagues figure that while many polar bears may starve in coming years, the resourceful animals just might survive disappearance.

    Polar bears survived a warm period about 125,000 years ago, when sea level was 12 to 18 feet higher than it is now and trees lived above the Arctic Circle, the scientists point out.  "They've been through the warm period before，" Rockwell said.

    The polar bears' potential movement to a diet of more eggs brought to mind a quote by Ilkoo Angutikjuak, an Inuit who lives in the Canadian province of Nunavut, in the February 2008 issue of Natural History magazine, Rockwell said. Angutikjuak said: "The animals will adapt. I've heard that because they depend on sea ice, polar bears will disappear, but I don't believe it. They are very adaptable. As the sea ice changes, polar bears might get skinnier and some might die, but I don't think they will disappear."

Western monarch butterflies(帝王蝶)spend their winters on the central California coast. A few months later, they produce young in the Central Valley and as far north and east as Idaho. But where they go in between remains an open question to biologists. Therefore, a group of biologists call on anyone who spots a monarch north of Santa Barbara this spring to get a quick shot(镜头)and email them the photo with a date and a location.

"Something's going on in early spring," said Cheryl Schultz, a professor at Washington State University Vancouver. "Winter survival isn't the problem in the short term, but they don't know whether the monarchs are not making it producing places, not finding plants to feed themselves along the way," she said.

The Western monarch population stood in the millions in the 1980s. In 2017, an annual count found 200,000 butterflies. In 2018, the number fell to about 30, 000-a figure that held steady last year. The monarchs' decline is part of a large trend among dozens of butterfly species in the West. What exactly caused the decline? Biologists attach it to a variety of reasons. Many chemicals are sprayed on the milkweed(乳草)monarchs will feed on. Climate change also plays a role in challenges facing monarchs. Yet, they're not nearly as threatening as those leading to loss of their living room. Farms used to have rough borders that were grounds for the plants monarchs love and live in. However, newly applied practices pushed crops to the edge of fields.

"Butterflies often have good and bad years. We do think there's potential to turn the situation around." Dr. Schultz said. And she said she saw two reasons for that. First, the population decline seen in 2017 ~ 2018 wasn't repeated last year. And second, she's seen butterfly populations recover before.

From rolling hills to mountain ranges, views make any road trip memorable, but for blin d passengers this is part of the experience they miss. Motor company Ford tries to change that. It teamed up with GTB Rom a and AedoProject—to develop a technology that will give those unfortunate passengers a way to feel nature's beauty through their car windows.

The prototype (原型) of the smart car window has a device with an outside-facing camera. With just a press of a button, the system takes a picture of the current view. The colorful picture is then turned into an image with different shades of grey through, LED lights, which vibrates (震动) differently. As the finger passes over different regions of the image, its shaking movements provide feedback through the sense of touch to the person using it. The smart window also comes with a voice assistant that uses AI to identify the scene and help the passengers get information on what they're seeing.

"As the prototype started taking shape, we realized we were giving birth to a completely new language that would give blind people a new chance to visualize and experience traveling," Federico Russo.-one director of GTBRoma, said. "When the idea was at its first stage, we looked for suppliers all around the world to make it come to life." He believes the technology can be employed not just in cars. "It could be introduced into schools and in stitutions for blind people as a tool that could be used in multiple ways."

The technology may show up in a Ford autonomous vehicle. It's known that the company is testing their technology and future business model and struggling to figure out how an autonomous vehicle gives different passengers the details needed to get from one destination to another. It's unclear when this technology will be made available. However, the idea of building something for the less advanced is indeed a kind and influential action.
