Everyone looks forward to progress, whether in one's personal life or in the general society. Progress indicates a person's ability to change the way he is living at the moment. Progress must lead a better way of doing things. All these, however, remains true only in so far as people want to accept technology and move forward by finding new and more efficient ways of doing things.

    However, at the back of the minds of many people, especially those who missed the “good old days”, efficiency comes with a price. When communication becomes efficient, people are able to contact one another no matter where they are and at whatever time they wish to. The click of a button allows people miles apart to talk or to see each other without even leaving their homes. With the communication gadgets, such as mobile phones and ipads, people often do not take the effect to visit one another personally. A personal visit carries with it the additional feature of having to be in the person's presence for as long as the visit lasts. We cannot unnecessarily excuse our selves or turn the other person off.

    With efficiency also comes mass production. Such is the nature of factories and the success of industrialization today. Factories have improved efficiency. Unskillful tasks are left to machines and products are better made and produced with greater accuracy than any human hand could ever have done. However, with the improvements in efficiency also comes the loss of the personal touch when making these products. For example, many handcrafts(手工艺品) are now produced in a factory. Although this means that supply is better able to increase demand, now that the supply is quick and efficient, the demand might fall because mass production lowers the quality of the handicraft and it is difficult to find unique designs on each item.

    Nevertheless, we must not commit the mistake of analyzing progress only from one point of view. In fact, progress has allowed tradition to keep up. It is only with progress and the invention of new technology that many old products can be brought back to their old state. New technology is required for old products to stay old.

    It is people's attitude towards progress that causes the type of influence that technology has on society. Technology is flexible. There is no fixed way of making use of it. Everything depends on people's attitude. The worst effects of progress will fall on those who are unable to rethink their attitudes and views of society. When we accept progress and adapt it to suit our needs, a new “past” is created.

    Colorado officials will stick to a plan to kill some mountain lions and bears to support the state's dropping mule deer (长耳鹿) population.

    Wednesday's vote permits organizations to kill up to 25 black bears and 15 mountain lions per year in the central and western parts of the state. The project will run for three years, to be followed by a six-year study of how deer populations respond to fewer predators(捕食者).

    The population of Colorado's mule deer has suffered a puzzling, years-long drop to about 450,000, which state officials said was about 110,000 fewer than there should be. A 2014 state study tied it to seven causes, including predators, whose number has greatly increased in recent years.

    Some experts, however, said the state should focus first on the human-led destruction(破坏) of mule deer habitat(栖息地). “The drop of the mule deer population is obviously not a simple problem with simple causes,” Brian Kurzel, director of the National Wildlife Federation, said. “By far, the greatest problem—the one that I think deserves the most attention in any science-based study—is habitat quantity and quality.”

    Kurzel pointed out that the U.S Bureau of Land Management recently agreed to create 15,000 new oil and gas wells somewhere in western Cororado, which was often called “the mule-deer factory”. There, the number of mule deer has fallen to about 30,000 from more than 100,000 in the early 1980s. Though state officials have known oil and gas development affects the population of mule deer, they didn't go against the plan.

    Other causes like building highways, population growth and human activities are also curbing the mule deer population, according to the study.

    State Parks and Wildlife officials don't necessarily disagree. They started a $4.5 million program as a way to gather research for later decisions.

    Sandra Cisneros was born in Chicago in 1954 to a Mexican American family. As the only girl in a family of seven children, she often felt like she had “seven fathers,” because her six brothers, as well as her father, tried to control her. Feeling shy and unimportant, she retreated(躲避)into books. Despite her love of reading, she did not do well in elementary school because she was too shy to participate.

    In high school, with the encouragement of one particular teacher, Cisneros improved her grades and worked for the school literary magazine. Her father encouraged her to go to college because he thought it would be a good way for her to find a husband. Cisneros did attend college, but instead of searching for a husband, she found a teacher who helped her join the famous graduate writing program at the University of Iowa. At the university's Writers' Workshop, however, she felt lonely－a Mexican American from a poor neighborhood among students from wealthy families. The feeling of being so different helped Cisneros find her “creative voice”.

    “It was not until this moment when I considered myself truly different that my writing acquired a voice. I knew I was a Mexican woman, but I didn't think it had anything to do with why I felt so much imbalance in my life, but it had everything to do with it! That's when I decided I would write about something my classmates couldn't write about.”

    Cisneros published her first work, The House on Mango Street, when she was twenty-nine. The book talks about a young Mexican American girl growing up in a Spanish-speaking area in Chicago, much like the neighborhoods in which Cisneros lived as a child. The book won an award in 1985 and has been used in classes from high school to graduate school level. Since then, Cisneros has published several books of poetry, a children's book, and a short-story collection.

    In 2016, designer Liz Ciokajlo received a task from the Museum of Modern Art (Moma) in New York: revisit the Moon Boot, a fluffy-looking snowshoe inspired by the footwear used by the Apollo astronauts.

    Launched in 1972 at the height of the lunar missions, the Moon Boot is an icon of the 20th Century's “plastic age” and the museum administrators wanted a new take on it.

    Ciokajlo set out to reimagine it. She knew only a biomaterial would work in a “post-plastic age”, but the designer also wanted a new destination to inspire it. Our generation's space travel obsession is not the Moon, she thought, but the red planet Mars. And Mars allows you to really think outside of the box.

    The task led her to an amazing biomaterial that had already attracted the attention of engineers innovating m building materials and of top space agencies like NASA and ESA. Her final design, a tall, female, rough-looking boot, can be made on board a spaceship with almost only human sweat and a few fungus spores (真菌孢子), ideal for a seven-month trip to Mars with limited check-in luggage.

    This magic biomaterial is mycelium (菌丝体), the vegetative part of the fungus It looks like amass of white thread-like structures, each called hyphae. Collectively, these threads are called mycelium and are the largest part of the fungus.

    Mycelium has amazing properties. It is a great recycler, as it feeds off a substrate to create more material, and has the potential of almost limitless growth in the right conditions. It can endure more pressure than conventional concrete without breaking. It is a known insulator and fire-retardant and could even provide radiation protection on space missions.

    On Earth it's currently used to create ceiling panels, leather, packaging materials and building materials, but in outer space it stands out for its architectural potential, says artist and engineer Maurizio Montalti, who has teamed up with Ciokajlo.

    For her revisited boot, Ciokajlo wanted to use the human body as the source for some of the building materials and decided to employ sweat. Reusing sweat is not entirely new in space exploration but a novelty approach for footwear. She thinks it might make astronauts feel closer to home during the long journey to Mars.

    The design is still hypothetical, because the real boot submitted for Moma and currently in display at the London Design Museum did use mycelium but not human sweat, as their deadline was too tight, but the science checks out.

    Known for its historic stone paths and traffic-jammed streets, France forgoes（放弃）traditional bricks and pavement for shiny solar panels（嵌板）with its new roadway project. French officials announced plans to construct a 1,000-kilometer-long solar roadway, with each kilometer capable of providing enough cheap, renewable energy to power 5,000 homes.

    “The maximum effect of the program, if successful, could be to furnish 5 million people with electricity, or about 8 percent of the French population,” Segolence Royal, France's minister of ecology and energy, said at a conference, reports Global Construction Review.

The street — or “Wattway”—was made possible through the cooperation between the National Institute of Solar Energy and French civil engineering firm Colas. Tests for the road will begin in the spring. The entire project will take an estimated five years to complete, but builders won't have to destroy existing roads in the meantime. Only about a quarter of an inch thick, the solar panels can simply be glued on top of existing streets and are durable（耐用的）enough to bear heavy traffic and weather conditions.

    Despite the bad traffic Parisians associate with their journey to work every day, the average French roadway is packed for only 10 percent of the day, according to Colas' figures. That will leave the solar street with the majority of the day to gather energy from the sun, which makes the project quite promising. The panels collect solar power through a thin layer of polycrystalline silicon（多晶硅）and change it into electricity. Electrical connections can be put into existing traffic structures.

    France won't be the first country to roll out a solar road. A 70-meter solar bike path was set up in the Netherlands in 2014. Within six months, the path had created enough to power a house for an entire year.

Plants, and the insects which rely on them, are the living foundations of our planet. But these foundations are under stress because we have a tendency to replace fields and forests with decorative trees and shrubs imported from around the world. Adding to the problem, our obsession (痴迷) with perfection leads us to use a lot of pesticides (杀虫剂).

These actions are part of the reason global biodiversity is crashing. There are over three billion fewer wild birds in North America than there were in 1970. Recent research shows that insect numbers, even in nature reserves, have fallen, and 40 percent of all insect species may be extinct within a few decades. This is discouraging news; however, there are actions we can take to help bring at least some species back.

The first step is to redefine our concept of "garden" to include more than just plants. We need to intentionally share our space, and not just with the birds, bees and butterflies that visit our flowers, but also with the little insects that may eat a part (very rarely all) of our plants. Therefore, we must limit pesticide use. It's crucial to support nature's recovery, and it's much better for everyone: no doctor has ever recommended long-term exposure to pesticides.

Many drought-tolerant plants brought in from across the planet are being passed off as ecofriendly. However, mostly they're not. Yes, you're saving water, but these foreign plants can become disasters when they escape our yards. Helping the environment can be about more than saving water. Even in drier areas, like the American West, the selection of attractive native plants to choose from is vast. If dry is your style, there are native wildflowers, flowering bushes and trees that allow you to save water and nature.

Xeriscapes (节水型园艺) leave many gardeners thirsting for green, and there's an important alternative that has been largely ignored. For those disenchanted with dry landscaping, using underappreciated and water-loving native plants to make your garden a real-life oasis (绿洲) could be lifesaving to wildlife. In nature, this unsung group of native plants is limited to riparian zones, the narrow belts of green along water bodies, but if consumers demand them, nurseries will increasingly carry these riparian species, and the presence of such plants in the garden will provide for many animals including not just butterflies and their relatives but also colorful birds.

The ideal garden would offer a combination of drought-tolerant native plants and a few species that need a little more water, providing options for little guests and the bigger ones that will come to eat them. As more creatures stop by to share our yards, we will be making nature, and us all, a little healthier.
