I went to the Tsavo National Park in northern Kenya for a film. We set off early for a distant water hole. A huge elephant covered with dry mud, drank calmly and deeply. He might have traveled 50 km to reach the water. He wasn't going to hurry now. We thought he'd drink a while and rest in the shade, and then drink again. What actually happened was that he drank deeply and stepped away. Then he suddenly fell down. Within minutes he was dead.

    We called animal doctor Jeremiah Poghon immediately. He removed the head of a poisonous arrow (箭) from the elephant's body, and let out over 100 liters of drug—the result of the elephant's meeting with a poacher (偷猎者) months before.

    Today's poacher fires an arrow, covered with poison, into the body of an elephant. If the poacher is lucky, the elephant might die in an hour or two; if not, he might have to follow the elephant for days before it dies. Often the arrow head fails to kill the elephant at once—it doesn't mean the poison won't finally kill the elephant, but it will be a slow death.

    Living in Tsavo through these times, I could see the results of poaching from time to time. When I think about the death of that elephant, what stays with me is the great silence after the shocking sound of his body hitting the ground. I couldn't escape the feeling that with the death of such a large animal, the world seemed to be a poorer and emptier place.

    People aren't walking any more—if they can figure out a way to avoid it.

    I felt superior about this matter until the other day I took my car to mail a small parcel. The journey is a matter of 281 steps. But I used the car. And I wasn't in any hurry, either, I had merely become one more victim of a national sickness: motorosis.

    It is an illness to which I had thought myself immune（免疫的）, for I was bred in the tradition of going to places on my own two legs. At that time, we regarded 25 miles as good day's walk and the ability to cover such a distance in ten hours as sign of strength and skill. It did not occur to us that walking was a hardship. And the effect was lasting. When I was 45 years old I raced—and beat—a teenage football player the 168 steps up the Stature of Liberty.

    Such enterprises today are regarded by many middle-aged persons as bad for the heart. But a well-known British physician, Sir Adolphe Abrhams, pointed out recently that hearts and bodies need proper exercises. A person who avoids exercise is more likely to have illnesses than one who exercises regularly. And walking is an ideal form of exercise—the most familiar and natural of all.

    It was Henry Thoreau who showed mankind the richness of going on foot. The man walking can learn the trees, flower, insects, birds and animals, the significance of seasons, the very feel of himself as a living creature in a living world, He cannot learn in a car.

    The car is a convenient means of transport, but we have made it our way of life. Many people don't dare to approach Nature any more; to them the world they were born to enjoy is all threat.To them security is a steel river thundering on a concrete road. And much of their thinking takes place while waiting for the traffic light to turn green.

    I say that the green of forests is the mind's best light. And none but the man on foot can evaluate what is basic and everlasting.

    Facebook founder Mark Zuckerberg took out full-page ads in British and American newspapers on Sunday to apologize for the Cambridge Analytica scandal（丑闻）, admitting the quiz app built by a university researcher that leaked（泄漏）Facebook data of millions of people was a “betrayal of trust”.

    Since the scandal broke, the public has become more aware and concerned about how their online behavior may be used for purposes to which they have not agreed. It emphasizes the urgent need for better protection of personal information.

    To better protect personal data privacy（隐私）, targeted laws are needed. More effective cooperation should be carried out to protect people's privacy online as soon as possible.

    Countries, such as the United States and China in particular, which are global leaders in the use of big data should accelerate legislation（立法）on how it can be collected and for what purposes it can be used.

    At the same time, a closer watch should be kept on the world's major internet companies, such as Apple, Facebook, Amazon, Google, Microsoft, Alibaba, Tencent and Baidu to ensure they do not acquire unnecessary personal information or misuse the information they obtain. Despite the huge challenge such personal data protection may pose to their established profit-making models, these companies should know that the more powerful they are, the bigger responsibilities they shoulder.

    Strengthened efforts for personal privacy protection do not mean that big data must not be used, but that it is used appropriately. Big data is like a mountain or gold, and overemphasis on its security at the expense of its use will undoubtedly waste a valuable resource. The key problem is how to promote its use while guaranteeing people's privacy to be protected.

    Miep Gies, the woman who hid the Dutch girl Anne Frank's diary from the Nazis to become one of the world's most-read books, died after a brief illness at the age of 100.

    It was Gies who guarded Anne's diary, and presented it to the girl's father, Otto, when he returned from the Auschwitz concentration camp(奥斯威辛集中营) at the end of World War Ⅱ—the only one of his family to survive.

    In her diary, Anne Frank wrote about her teenage life hiding from the Nazis in Amsterdam from 1942 to 1944, when the Nazi police discovered her and her family's hiding place. The diary, first published in 1947, has been translated into 70 languages.

    Anne Frank expressed a great wish to live on after her death. Miep Gies saw it as her duty to help in making this happen.

    Born in Vienna in 1909, Gies moved to the Netherlands at the age of 11. In 1933, she began working for Otto Frank at his trading company. At great risk to her own safety, she and four other helpers brought food and supplies to the Frank family hiding in a secret office building for more than two years.

    When she turned 100, Gies tried to play down her own role. "I'm not a hero," she said. "It wasn't something I planned in advance. I simply did what I could to help."

    Every day she received letters from all over the world with questions about her relationship with Anne Frank and her role as a helper. Gies received many honors for her role, including from the Netherlands, Germany and Israel.
