We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置)well after they go out of style. That's bad news for the environment—and our wallets—as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life—from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s.Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992.Digital cameras arrived on the scene in 1997.And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones.“The living-room television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house,” said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007.We're not just keeping these old devices—we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放)more than doubling during the 1992 to 2007 window.
So what's the solution (解决方案)?The team's data only went up to 2007,but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
In 1985, 16-year-old Douglas Casa, ran the championship 10, 000 meter track race at the Empire State Games. Suddenly, with just 200 meters to go, he collapsed on the final straightaway, with his body temperature at dangerous levels. He had suffered an exertional heat stroke(运动型中暑)or sunstroke. {#blank#}1{#/blank#}
From ancient soldiers on the battlefield to modern warriors on the gridiron(足球球场), exertional heat stroke, has long been a serious concern. And unlike classical heat stroke, which affects people such as babies and the elderly during heat waves, exertional heat stroke is caused by intense exercise in the heat. {#blank#}2{#/blank#}
So how do you diagnose an exertional heat stroke? The main criterion is a core body temperature greater than 40℃ along with signs of central nervous system disfunction such as confused behavior, or loss of consciousness.
As far as treatment goes, the most important thing to remember is cool first, transport second. The human body can withstand a core temperature above 40℃ for about 30 minutes before cell damage sets in. {#blank#}3{#/blank#}After any athletic or protective gear has been removed from the victim, place them in an ice water tub while stirring the water and monitoring vitals continuously. {#blank#}4{#/blank#}As you wait, itˈs important to keep the victim calm while cooling as much surface area as possible until emergency personnel arrive. If medical staff are available on site, cooling should continue until a core temperature of 38. 9℃ is reached.
{#blank#}5{#/blank#}As Dr. J Levick wrote of exertional heat stroke in 1859, "It strikes down its victim with his full armor on. Youth, health and strength oppose no obstacle to its power. " But donˈt be frightened so much for it has been 100% survivable with proper care.
A. Fortunately he survived with immediate treatment. B. When possible seek out places with air-conditioners. C. So itˈs necessary to start cooling as quickly as possible. D. But emergency services should be called before you start. E. The sun can also take lives away if people are not careful. F. So far it has been one of the top three killers of athletes in training. G. It is important to keep the body temperature close to its normal temperature. |
