Social media, texting and e-mail all make it much easier to communicate, gather and pass information, but they also present some dangers. By removing any real human engagement, they enable us to develop our abnormal self-love without the risk of disapproval or criticism. To use a theatrical metaphor (隐喻), these new forms of communication provide a stage on which we can each create our own characters, hidden behind a fourth wall of tweets, status updates and texts. This unreal state of unconcern can become addictive as we separate ourselves a safe distance from the cruelty of our fleshly lives, where we are imperfect, powerless and insignificant. In essence, we have been provided not only the means to be more free, but also to become new, to create and project a more perfect self to the world. As we become more reliant on these tools, they become more a part of our daily routine, and so we become more restricted in this fantasy.

So it is that we live in a cold era, where names and faces represent two different levels of closeness, where working relationships occur only through the magic of email and where love can start or end by text message. An environment such as this reduces interpersonal relationships to mere digital exchanges.

Would a celebrity have been so daring to do something dishonorable if he had had to do it in person? Doubtful. It seems he might have been lost in a fantasy world that ultimately convinced himself into believing the digital self could obey different rules and regulations, as if he could continually push the limits of what's acceptable without facing the consequences of "real life."

Past research has found health and wellness benefits of nature for humans, but a new study shows that wildness in urban areas is extremely important for human well-being.

The research team focused on a large urban park. They surveyed several hundred park-goers, asking them to submit (呈递) a written summary online of a meaningful interaction they had with nature in the park. The researchers then examined these submissions, coding (编码) experiences into different categories. For example, one participant's experience of "We sat and listened to the waves at the beach for a while" was assigned the categories "sitting at beach" and "listening to waves."

Across the 320 submissions, a pattern of categories the researchers call a "nature language" began to emerge. After the coding of all submissions, half a dozen categories were noted most often as important to visitors. These include encountering wildlife, walking along the edge of water, and following an established trail.

Naming each nature experience creates a usable language, which helps people recognize and take part in the activities that are most satisfying and meaningful to them. For example, the experience of walking along the edge of water might be satisfying for a young professional on a weekend hike in the park. Back downtown during a workday, they can enjoy a more domestic (国内的，家庭的) form of this interaction by walking along a fountain on their lunch break.

"We're trying to generate a language that helps bring the human-nature interactions back into our daily lives. And for that to happen, we also need to protect nature so that we can interact with it," said Peter Kahn, a senior author of the study.

Attenborough, who received a degree in natural sciences from Cambridge University, joined the BBC full-time in 195. He travelled around the world with his Zoo Quest programme, highlighting different creatures. Afterwards, he created his iconic series Lifeon Earth in 1979. Since then, he has created and starred in countless programmes which have brought nature closer to viewers around the world.

His recent documentary with World Wildlife Fund, David Attenborough: A Life On Our Planet, often returns to a theme which has predominated in Attenborough's later work. He reflects on just how much the environment has changed in his-decades of observation and how swiftly time is running out before·further serious damage can be prevented. This programme was widely streamed and considered a "wake up call" for the world. While Attenborough is far from the first or only voice to raise this call, his reach as a respected and powerful figure within the BBC provides a useful platform.

Although he has received countless awards, Attenborough has used recent accolades (荣誉) as a chance to focus once more on the planet. Shortly after winning the Champions of the Earth Lifetime Achievement Award in 2022, he sent an urgent message about the state of the planet to all viewers. in Frozen Planet Ⅱ. Even after his 97th birthday, he continues to write and speak on preserving the UK and the world for future generations.

Paths have become familiar after years of hiking. But rocks and tree roots have magically appeared from previously1 ground.

Certainly I hit my toe against or2 on some unseen barriers. Fallen branches from last night's storm3 in wait. Layers of autumn leaves create a false floor through which my trusting footsteps4. Sometimes a piece of moon donates some light to the mystery path. But when skies are dark, there are no5 clues (线索) for where I step.

My very first night hike was during summer camp on a warm August night in the woods. Our leader6 bright flashlights so we would not scare away the night creatures we hoped to find.

"See with your feet," the leader told us over and over again.

But mistakes11 happen. My foot gets caught on a trip and I fall. Since the pace is slow, there is little damage except to pride. Once12, I pause to feel the firmness of earth beneath me.

On my way home, as dawn13 day, I think about how similar night hikes are to journeys through life.

The same rules often14 for both: slow down, concentration, "see" with new senses — and don't be scared. Although the path is full of15 — hidden barriers, false surface, wet floor — the earth is solid and firm beneath. It is the nature of night ground. It is the nature of life.
