The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and
bringing about a lot of damage. The change in how coffee is grown from shade-grown，production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world's ecological balance.
On a local level, the damage of the forest required by full-sun fields affects the area's birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees' flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.
On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.
Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate,
and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.
It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology.
But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of
the planet and mankind is surely worth more than an inexpensive cup of coffee.

    “We are good mothers,” I said to my friend, as we sat on our comfortable beach chairs under our beach umbrella and watched our children playing in the waves.

    Out of nowhere, the children took off running. About fifty yards from us, a man—maybe in his fifties—was fishing. The children stood next to him and watched with their little mouths hanging open as he cast the fishing lines. He smiled at them. They ran back to us—all except my three-year-old daughter, Drew.

    My heart beat fast with horror. “Drew! Come here! Play with your friends!” I shouted, very aware that my speeches about not talking to strangers weren't working. It seemed that many parents heard of horrible stories about children being taken away by strangers. Responsible mothers should teach their children that the world is a dangerous place. So I felt relieved when Drew ran towards me and took hold of a shovel (铲子). Then she looked me in the eye: “I want to be with the person.”

    Again, she approached the middle-aged man, and started digging next to him.

    Several seconds later, she returned, waving something shiny.

    “Look, Mommy! A toy fish!”

    It was, indeed, a toy fish—yellow and rubber. This must have been what he was using to attract the fish. And he'd given it to Drew. The three other children were deeply impressed, and they didn't try to hide how jealous(妒忌的)they were—clearly, they all wanted the fish.

    “My friend gave me that fish!” Drew shouted loudly. The sand in front of the umbrella turned into a preschool cage match with a yellow rubber fish flying through the air. I felt like I might cry myself.

    Unexpectedly, there he was: the man, standing right next to us with three more rubber fish in hand. He handed them to each of the children. By their faces, you would have thought he was actually the really kind big brother.

    “Thank you,” I said, realizing that there is good and kindness in strangers.

The Pathfinder

    When we found him, he was a sorry sight. His clothes were torn, his hands bleeding. Before we reached him, we saw him fall. He lay a moment. Then he pulled himself to his feet, walked unsteadily a few yards through the woods and fell again.

    After we got him out, we went back to find the gun that he had thrown down. His tracks showed that for two days he had circled in the forest, within 200 yards of the road. His senses were so dulled by fear and tiredness that he did not hear the cars going by or see the lights at night.

    We found him just in time.

    This man, like others before him, had simply been frightened when he knew he was lost. What had been a near disaster might have turned out as only a pleasant walk, had he made a few preparations before he stepped from the highway or off a known path.

    Whatever sense of direction that a man may have, it's still largely a question of observation. A skilled woodsman always keeps an eye on his surroundings. He notes that the shape of a mountain, the direction water flows through a swamp, and the way a tree leans across a path. With these in mind, he may be turned around many times, but he is seldom lost.

    There are exceptions, of course, and once in a while a man does come across some strange problem that puts him into the “lost” situation. A rainstorm or sudden blizzard may catch him without a compass (指南针) in his pocket. Darkness may find him in a rough area, where travel is dangerous without a light.

    When this happens, the normal first reaction (反应) is the fear of being laughed at as a result of his poor knowledge in the woods. He may also be concerned about the inconvenience that he will cause his friends when he doesn't show up. This false pride may lead him to keep on the move in a false effort to find his way against all difficulties.

    The person who thinks ahead is seldom in great danger. He'll be safe if he observes carefully, thinks ahead, and remains calm.

    New Zealand's chief conservation (环保) officer, Lou Sanson, caused an argument in October by suggesting that it should be time to start charging tourists for entering national parks. New Zealanders are keen fans of these parks. Many would be annoyed at having to pay. But many also worry about the incoming foreign tourists who have been seeking the same fun.

    In 2016 New Zealand hosted 3.5m tourists from overseas; by 2022 more than 4.5m are expected every year — about the same as the country's population. Tourism has become the biggest export. The national parks, which make up about one-third of the country, are a huge draw. About half of the foreign tourists visit one. They are keen to experience the natural beauty promised by the country's "100% Pure New Zealand" advertising campaign (and shown off in the film adaptations of "The Lord of the Rings" and "The Hobbit", which were shot in New Zealand's breath-taking wilderness).

    But for every happy foreign couple posting for a selfie next to a tuatara (楔齿蜥) there is a New

    Zealander who remembers the way things used to be — when you could walk the tracks without running into crowds at every clearing. Many locals now wonder why their taxes, as they see it, are paying for someone else's holiday. Mr. Sanson would seem to agree. Entry fees could be used to upgrade facilities such as car parks and trails. A charge could also help reduce numbers at some of the popular locations by making it cheaper to use lesser-known, but no less beautiful, trails far away from home.

    Some are not so sure it would work. Hugh Logan, a former chief of conservation for the government who now runs a mountain climbing club, worries it would cost too much to employ staff to take money from hikers at entrances. It would also be difficult to prevent tourists from entering the parks without paying.

    Some argue that it would be easier to charge visitors a "conservation tax" when they enter the country. The Green Party, the third-largest in parliament (议会), says that adding around NZ$18 ($12.50) is still acceptable to foreign tourists. But some travel companies don't quite agree with the idea. They note that tourists already contribute around NZ$1.1bn through the country's 15% sales tax. Better, such firms say, to use foreign tourists' contribution to this tax for the protection of the parks.

    Among the fiercest critics of a charge are those who point out that free access to wilderness areas is an important principle for New Zealanders. It is documented in a National Parks Act (法案) which inspires almost constitution-like devotion among the country's nature-lovers. Mr. Sanson has a rocky path ahead.

Foldable phones are once again facing questions about their durability(耐久性).The Galaxy Z Flip and the Motorola Razr are now both available to buy in the US-but early reports suggest the screens are easily damaged.

One media published photos of two layers of the Razr's display separating, affecting the touch screen. The Galaxy flip, meanwhile, boasts(自夸)a "flexible glass" display—but tests appear to show it scratching(刮擦)as easily as plastic.

In a statement, Samsung said the display had a protective layer, and had undergone extensive testing. "While the display does bend, it should be handled with care, "it said.

The Z Flip's "pretty thin glass" is one of Samsung's primary marketing messages for the new phone. But a durability test conducted by popular Zack Nelson, a regular buyer, suggested it was no more durable than soft plastic screen, and could even be dented(痕)by fingernail.

Nelson said Samsung's screen scratched exactly how plastic screen would react. "I don't know what material this is, but Samsung definitely shouldn't be calling it glass," he said. He found that the screen of the Motorola Razr scratched as easily but it is not marketed as "glass".

The Motorola Razr was put on sale 13 days ago in the US, but Raymond Wong, an editor says the flexible screen on his handset has already broken. The upper layer of the Razr's screen separated from the bottom, creating "a giant horizontal air bubble" for no apparent reason. He wrote that the fault appeared after 45-minute train ride during which the phone was in his pocket. The screen was completely warped from hinge-to-hinge with the top layer raised like a poorly applied screen protector. But Mr. Wong said that apart from the visual problem, the damage has affected the responsiveness of the touchscreen.
