The oddness of life in space never quite goes away. Here are some examples.

    Meet big brother Blue and his sisters Meadow and Little Willow, a family of three blind cats that got adopted by the family Catherine Magno.

    Their story starts just before the Christmas of 2014 when the kittens (小猫) were found in an abandoned house in Dubai. By then they had already lost their sight due to a cat flu that was left untreated by their previous (先前的) owner. After that they came to an animal home. At some point, brother Blue almost got adopted by the previous owner's neighbor, but the poor confused cat couldn't bear living without his sisters and cried all night while searching for them. Soon they were all united in the animal home until the important night of 19 February 2015, when Catherine took under her wing.

    “I had zero experience having adopted my first ever rescue kitten just a couple of months ago,” Catherine said. “But their story touched my heart so much that I couldn't bear the thought of them being put in a cage for a very long time or even worse.”

    Catherine was worried about the special needs of her new pet friends: “My worry was that it's going to not only be challenging but also require a lot of adjustments on my part,” but apparently it wasn't that much different. “The only adjustment early on was keeping everything where it was but they are soon adaptive(适应的).” And as she wonderfully put it: “Blind pets see through their hearts.”

    {#blank#}1{#/blank#} When a starving man gets a meal, he begins to think about an overcoat; when a manager gets a new sports car, visions of country clubs dance into view.

    The many wants of mankind might be regarded as making up several levels. {#blank#}2{#/blank#}.

    The first and most basic level of wants is food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. {#blank#}3{#/blank#} It included such items as cars and new houses.

    By 1957 or 1958 this third level of wants was fairly well satisfied. Then, in the late 1950s a fourth level of wants appeared: the “life-enriching” level. While the other levels mean physical satisfaction－the feeding, comfort, safety, and transportation of the human body－this level stresses mental needs for recognition, achievement and happiness. It includes a variety of goods and services, many of which could be called “luxury” items(奢侈品). Among them are vacation trips, the best medical care, and entertainment. {#blank#}4{#/blank#}

    On this level, a greater percentage of consumer spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?

    A fifth level probably would be wants that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime and prejudice. {#blank#}5{#/blank#} In this way, we can enjoy more fully the good things on the first four levels.

 A．Then a third level appeared.

 B．Human wants seem endless.

 C．When there is money enough to satisfy one level of wants, another level appears.

 D．There are several levels of wants in one's life.

 E．At this stage, we now may seek to ensure the health, safety, and leisure.

 F．Also included here are fancy foods and the latest styles in clothing.

 G．Different people have different wants on each level 

    Many years ago, people relied on the sun, the moon and stars to find their way around. Later, the compass was introduced. And now, we have satnav（卫星导航）systems to guide us. A satnav system uses groups of satellites to show the user's location. They send information to a receiver, such as a smart phone, to show us where we are.

    The earliest built satnav system is the Global Positioning System, which belongs to the US. Then there is Russia's Global Navigation（导航）Satellite System, the European Union's Galileo and China's own satellite navigation system, BeiDou.

    On October 14, 2017, an ARJ21-700 plane, which was the first domestically-produced jet equipped with the BeiDou navigation system, successfully completed a test flight. The results showed the performance of the system developed by China matches that of similar systems produced abroad, according to the Commercial Aircraft Corporation of China.

    Since its introduction in 2000, the Beidou navigation system has seen increasing numbers of applications linked to everyday life, from shared bikes to farming.

    When it comes to shared bikes, smart locks that support BeiDou chips offer more accurate positioning than others, making it easier to find a bike.

    Farmers can use BeiDou-enabled tractors to plow（犁）the soil and use unmanned aircraft with BeiDou to sow seeds, which can improve efficiency and make better use of resources. BeiDou's farming applications have spread from Heilongjiang province to Beijing, Liaoning, Shanxi, Hubei and other regions across China.

    With its many uses, the Beidou navigation system is even playing a big role in the Belt and Road Initiative（— 带—路）. “To date, the BeiDou system has covered most parts of the Asia-Pacific region, as well as counties along the Silk Road Economic Belt and the 21^st Century Maritime Silk Road” said Yang Changfeng, Chief designer of the BeiDou system.

    Today, there are more than 20 BeiDou satellites above our heads, and China plans to launch even more this year to expand the BeiDou network to better serve the Belt and Road Initiative.

    “As BeiDou expands its overseas reach, it will be increasingly popular in the logistics （物流）industry,” said Miao Qianjun, secretary-general of the navigation services association. “Ships, for example, can use it to position themselves while sailing across oceans to European countries, no longer limited to Southeast Asian regions in the near future.”

Everyone gets anxious when the world takes an uncertain turn. And often, we treat that anxiety with a little panic buying.

A study published last year in the Journal of Consumer Research found that people buy things in troubled times as a means of keeping control over their lives. The researchers noted that utility items — specifically, cleaning products — tend to move most quickly from store shelves. The hoarding (囤积) of toilet paper, as perhaps the most fundamental cleaning product, may represent our most fundamental fears. An invisible enemy moves slowly and quietly towards us. We need to hold on to something in uncertain times. Maybe a hoard of toilet paper brings promises.

The thing is, it's not actually going anywhere. For all the sharp words and even sharper elbows thrown around by the crazy toilet paper shoppers, they seem to be missing one essential fact: There is no toilet paper shortage.

As The New York Times points out, shop owners that see their shelves emptied often fill up the shelves again in a day, often in just a few hours.

"You are not using more of it. You are just filling up your closet with it," Jeff Anderson, president of paper product manufacturer Precision Paper Converters, tells the Times.

The thing is, the toilet paper-obsessed shoppers have been infected with something many times more contagious (感染性的) than any coronavirus: fear.

"People are social creatures. We look to each other for cues for what is safe and what is dangerous," Steven Taylor, a clinical psychologist at the University of British Columbia, tells Fox News. "And when you see someone in the store panic-buying, that can cause a fear contagion effect. People become anxious ahead of the actual infection. They haven't thought about the bigger picture, like what are the consequences of hoarding toilet paper."

Recycled, reused and renewable textiles（纺织品）only go so far in solving the fast-fashion crisis, writes Alexandra Carlton. The answer may lie in consumption.

Australia is the world's second-largest consumer of clothing, generating 800,000 tonnes of textile waste yearly. Individuals consume about 27 kilograms of new clothes annually and cast 23 kilograms of waste. Globally, the situation is even more severe, with an estimated 92million tonnes of clothing waste produced each year. This equates to a truckload of clothes entering landfills every second.

If you want to stop our unwanted clothes from jamming the planet, you'd assume that reusing and recycling would lead the discussion. However, full clothes recycling—breaking clothes down to their base fibres to create new ones—is no simple task. Clothes consist of various fibres, fasteners, and decorations that traditionally require painstaking manual（手工的）separation. Yet, innovation is underway, such as the Swedish large-scale sorting facility Siptex, where textiles can be sorted by color and material using infrared（红外线）technology.

Brands like Adelaide's Autark focus on minimizing output. "I keep my collections tightly designed and production numbers slim," says designer Sophia McMahon. Sometimes this means she doesn't have the exact clothes someone wants in store, but customers are patient while she makes items to order because they understand her brand's essence.

Startups like AirRobe are giving clothes a second life and could be part of the solution. The clothing resale market is currently worth 49 billion and is expected to reach 103 billion by 2025. AirRobe lets customers add new purchases to their digital wardrobe so they can be resold later without uploading photos or descriptions. "The ‘re-economy'—the reuse and recycle market sector—will be a real opportunity for us," says Erica Berchtold, CEO of The Iconic.

Researchers Samantha Sharpe and Taylor Brydges from the University of Technology Sydney advocate a widespread shift among consumers towards buying fewer, higher-quality clothes besides these innovations.
