2 . I wanted the pleasure of being in Africa again. Feeling that the place was so large that it contained many untold tales and some hope and comedy and sweetness too, I aimed to reinsert myself in the bundy, as we used to call the bush, and to wander around. There I had lived and worked, happily, almost forty years ago, in the heart of the greenest continent.

In those old undramatic days of my school teaching in the bundu, folks lived their lives on bush paths at the end of unpaved roads of red clay, in villages of grass-roofed huts. They had a new national flag, they had just gotten the vote, some had bikes, many talked about buying their first pair of shoes. They were hopeful, and, so was I, a schoolteacher living near a settlement of mud-huts among trees and fields—children shouting at play; and women bent double—most with infants on their backs—hoeing(锄地) the corn beans; and the men sitting in the shade.

The Swahili word safari means “journey”, it has nothing to do with animals, someone “on safari” is just away and unobtainable and out of touch. Out of touch in Africa was where I wanted to be. The wish to disappear sends many travellers away. If you are thoroughly sick of being kept waiting at home or at work, travel is perfect: let other people wait for a change. Travel is a sort of revenge(报复) for having been put on hold, or having to leave messages on answering machines, not knowing your party’s extension, being kept waiting all your working life. But also being kept waiting is the human condition.

Travel in the African bush can also be a sort of revenge on mobile phones and email, on telephones and the daily paper, on the aspects of globalization that allow anyone who chooses to get their hands on you. I desired to be unobtainable. I was going to Africa for the best of reasons—in a spirit of discovery—simply to disappear, to light out, with a suggestion of I dare you to try to find me.

Home had become a routine, and routine made time pass quickly. I was a sitting duck in this predictable routine: people knew when to call me, they knew when I would be at my desk. I was in such regular touch that it was like having a job, a mode of life I hated. I was sick of being called up and asked for favors, hit up for money. You stick around too long and people begin to impose their own deadlines on you.

Satellites Can Help Us Fight Climate Change

At the beginning of 2021, President Joe Biden exclaimed that “science is back” as we continued our efforts to     1     the COVID emergency. That phrase continues to ring true across the federal government. Science and its applications are being used at every agency to deal with public health     2    , build new transportation infrastructure, inform policy decisions and tackle the climate crisis.

Recently the Interior Department’s U.S. Geological Survey assumed     3     of Landsat 9 from NASA, which built and launched it in 2021.This satellite is designed to     4     Earth’s land, water and other natural resources. Landsat missions support environmental sustainability and climate resilience. The Landsat program, which launched in July 1972, has helped us understand our planet and the changes that are occurring on it. That partnership has propelled research and observation forward through the launch of     5     Landsat satellites, each replacing its predecessors and working in tandem with new capabilities and strengths.

I attended the historic launch of Landsat 9 in California. It was nothing     6     of amazing. I toured the mission control center and met a young scientist from the Navajo Nation living far away from home. She uses Landsat     7     to see her home from many miles away, and with such data, she enables her community to manage water resources in the face of a changing climate. This is the power and beauty of science at work.

All around the globe, scientists are using Landsat and other imagery to interpret what is happening on Earth today and to compare it with the 50 years’     8     of data the Landsat program has collected.

This science-based program and those like it across federal agencies are powerful tools in our efforts to responsibly manage our resources. Their prioritization helps to demonstrate the Biden-Harris administration’s commitment to lead with science. So, too, the resources provided through the president’s Bipartisan Infrastructure Law and Inflation Reduction Act will be key to the development of longer-term sustainability measures as we     9     to climate change, including building more resilient communities and protecting our natural environment.

Landsat NEXT is the upcoming mission we will develop with NASA to power better science and decision-making for the next 50 years. Science is indeed     10     us on a path to a brighter future.

Most underrated pleasures of one’s life

One of the biggest drivers of good relationships in our lives is a developed level of understanding in those relationships. The relationships     1     this understanding end up creating too much maintenance work. So it becomes more like luggage or at least something that needs attention or care rather than fun.

I realized it with a couple of friends of mine. Recently my “friend ecosystem” had a sudden change. A couple of them     2     (leave) although I still have a couple around. I am also adding a couple of new ones.

The whole change made me thoughtful. I started to think about the cause of being better friends with some. It turns out that among the large number of other factors, one of the key ones is     3     (understand). It can then be extended to personal and even business relationships.

While     4     (hire) a key employee, one can be sure that it will work well if the other person enjoys and understands you well. It will be far     5     (productive) as the relationship related maintenance is low and you can focus on actual output. It     6     help you even when you are looking for funding partners, seed capital or business joint ventures (企业).

Finally, how do you ensure you are understood? To start with, make sure that the people who     7     (matter) to you in any capacity like business, managerial, personal or family have an open relationship with you. Creating an open environment     8     others can discuss constructive aspects or difficult discussion is important.

Being caring and respectful to     9     and being truthful are two different things. Truthfulness is as important as being respectful and caring. In the long term, truthfulness will result in a caring relationship.     10     you are understood well and have an open relationship, you can’t be truthful.

When you get to that level with the person where you are completely understood, it will be an awesome feeling!

8 . The goal of this book is to make the case for digital minimalism, including a detailed exploration of what it asks and why it works, and then to teach you how to adopt this philosophy if you decide it’s right for you.

To do so, I divided the book into two parts. In part one, I describe the philosophical foundations of digital minimalism, starting with an examination of the forces that are making so many people’s digital lives increasingly intolerable, before moving on to a detailed discussion of the digital minimalism philosophy.

Part one concludes by introducing my suggested method for adopting this philosophy: the digital declutter. This process requires you to step away from optional online activities for thirty days. At the end of the thirty days, you will then add back a small number of carefully chosen online activities that you believe will provide massive benefits to the things you value.

In the final chapter of part one, I’ll guide you through carrying out your own digital declutter. In doing so, I’ll draw on an experiment I ran in 2018 in which over 1,600 people agreed to perform a digital declutter. You’ll hear these participants’ stories and learn what strategies worked well for them, and what traps they encountered that you should avoid.

The second part of this book takes a closer look at some ideas that will help you cultivate (培养) a sustainable digital minimalism lifestyle. In these chapters, I examine issues such as the importance of solitude (独处) and the necessity of cultivating high-quality leisure to replace the time most now spent on mindless device use. Each chapter concludes with a collection of practices, which are designed to help you act on the big ideas of the chapter. You can view these practices as a toolbox meant to aid your efforts to build a minimalist lifestyle that works for your particular circumstances.

9 . As cities balloon with growth, access to nature for people living in urban areas is becoming harder to find. If you’re lucky, there might be a pocket park near where you live, but it’s unusual to find places in a city that are relatively wild.

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 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 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.
