RomainLacombe_2018U-_个人空气质量追踪器——让你了解你呼吸的空气_
So for the past 12 years, 在过去的12年中,
I've been obsessed with this idea that climate change is an information issue that computers will help us fight. 有一个想法一直 在我脑海中挥之不去: 气候变化是一个事关信息的问题, 而电脑会帮我们解决这个问题。
obsessed:v.使痴迷;使迷恋;使着迷;(obsess的过去式和过去分词) issue:n.重要议题;争论的问题;v.宣布;公布;发出;发行;
I went from data science to climate policy research, from tech to public service , in pursuit of better data to avoid the wasted energy, resources , opportunities that lead to runaway carbon emissions . 我从数据科学转向气候政策研究, 又从科技转向公共服务, 只为了追求更好的数据, 以避免因浪费能源、资源和机会 导致的碳排放失控。
policy:n.政策,方针;保险单; public service:n.公共事业;公营事业;公益事业(或服务);政府; in pursuit of:寻求,追求; resources:n.[计][环境]资源; v.向…提供资金(resource的第三人称单数); runaway:adj.逃亡的;逃走的;n.逃跑;逃走的人; carbon:n.[化学]碳;碳棒;复写纸;adj.碳的;碳处理的; emissions:n.(光、热、气等的)发出,排放;排放物;散发物;(emission的复数)
Until one day, running in the streets with a friend, it hit me: the same cars, factories, power plants whose emissions are wrecking our climate over time also release harmful, local pollutants that threaten our health right here and right now. 直到某一天,当我和朋友 一起在街上跑步时,我突然想到: 那些汽车、工厂、发电厂, 长期来看,它们排放的废气 正在破坏我们的气候, 同时它们还在当地排放有毒污染物, 此时此刻,正威胁着我们的健康。
wrecking:v.破坏; n.破坏; (wreck的现在分词) release:v.释放;发射;让与;允许发表;n.释放;发布;让与; pollutants:n.[环境]污染物(pollutant的复数);
All this time I'd focused on the long-term environmental risk when I should have been up in arms about the immediate health impact of pollutants in the air. 我一直专注于长期环境威胁, 但我真正应该反对的 却是空气中那些 会立刻损害健康的污染物。
long-term:adj.长期的;从长远来看; up in arms:竭力反对;进行武装斗争; impact:n.影响;效果;碰撞;冲击力;v.挤入,压紧;撞击;对…产生影响;
Air pollution is a burning public health crisis . 空气污染是一项 非常严重的公共健康危机。
crisis:n.危机;危险期;决定性时刻;adj.危机的;用于处理危机的;
It kills seven million people every year, it costs five trillion dollars to the world economy and, worst, it robs us of our most precious gift, the years in our lives: 每年7百万人因此而丧生, 它对世界经济造成了 50亿美元的损失, 更糟糕的是,它会削减 对我们至关重要的东西, 我们的寿命长度:
trillion:n.[数]万亿;adj.万亿的;num.[数]万亿; economy:n.经济;节约;理财; precious:adj.宝贵的;珍贵的;矫揉造作的;
six months of life expectancy in my hometown of Paris and up to three, four, five years in parts of India and China. 它使得我家乡巴黎的 人均寿命缩短6个月, 使得印度和中国部分地区的 人均寿命最高缩短3到5年。
life expectancy:预期寿命;
And in the US, more people die from car exhaust than from car accidents. 而在美国,汽车尾气造成的 死亡人数甚至高于交通事故。
exhaust:v.耗尽; n.(车辆、发动机或机器排出的)废气;
So how do we protect ourselves from pollution? 那么,我们该如何 保护自己远离污染呢？
The reason it's difficult is an information gap . 我们之所以很难保护自己, 是因为信息缺失。
gap:n.差距;间隙;缺口;间隔;v.使豁裂;豁开;
We simply lack the data to understand our exposure . 我们缺少关于周围环境的信息。
exposure:n.暴露;显露;揭露;面临;
And that's because the way we monitor air quality today is designed not to help people breathe but to help governments govern. 因为现在空气质量监测系统的目的 并非保证人们的呼吸质量, 而是帮助政府进行监管。
air quality:n.空气质量;
Most major cities operate networks of air-quality monitoring stations like this one in London, to decide when to cut traffic or when to shut down factories. 大多数城市都有空气质量监测站, 就像伦敦的这个, 用来决定在什么时候进行 交通管制,或是让工厂停工。
And these machines are like the computers from the '60s that filled entire rooms. 这些机器就像是60年代的电脑, 能占据整个房间。
They're incredibly precise but incredibly large, heavy, costly -- so much that you can only deploy just a few of them, and they cannot move. 它们非常精准,但是体积庞大, 十分笨重,价格昂贵—— 因为这些原因,你只能部署有限的几台, 而且无法灵活的移动它们。
incredibly:adv.难以置信地;非常地; precise:adj.准确的;确切的;精确的;明确的; costly:adj.昂贵的;代价高的; deploy:v.部署;利用;[军事]展开;(使)张开;
So to governments, air pollution looks like this. 所以在政府眼中, 空气污染只是屏幕上的几个点,
But for the rest of us, air quality looks like this. 但对于其他人而言, 空气污染到处都是。
It changes all the time: hour by hour, street by street, up to eight times within a single city block. 空气质量时刻都在变化: 每个小时,每条街道, 在一个街区中 变化就有八次之多。
And even more from indoor to outdoor . 如果你算上市内和户外, 变化次数就更多了。
indoor:adj.(在)室内的;在户内进行的;在室内用的; outdoor:adj.户外的;露天的;
So unless you happen to be walking right next to one of those stations, they just cannot tell you what you breathe. 除非你正好走过一个监测站, 不然你无法得知自己呼吸的空气质量。
So what would environmental protection look like if it was designed for the age of the smartphone ? 如果它被设计用于智能手机, 环境保护会变成什么样呢?
smartphone:n.智能手机;
So for the past three years, my team and I have been building a technology that helps you know what you breathe and fits in your hand. 在过去的3年中, 我和我的团队研发了一项技术, 通过一台手持设备来帮助你们 了解当前的空气质量。

It's packed with miniature sensors that monitor the most important pollutants in the air around you, like nitrogen oxides , the exhaust gas from cars, or particulate matter that gets into your bloodstream and creates strokes and heart issues . 它内置微型传感器, 能够监测你周围空气中最大的污染物, 例如,氮氧化物, 也就是汽车尾气的主要成分, 或是能够进入你血液 造成中风和心脏疾病的悬浮颗粒,

And that makes this data actionable and helps you understand what you're breathing by telling you where and when you've been exposed to poor air quality, and that way you can make informed decisions to take action against pollution. 上述的原因让这项数值 具有实际的参考价值, 能够让你了解你呼吸的空气质量, 它会提醒何时何地 在你周围的空气质量较差, 以帮助你做出明智的决定, 行动起来,对抗污染。

route:n.路线;路途;固定线路;途径;v.按某路线发送; peaking:n.剧烈增加; v.憔悴;
Over time you build better habits to decrease your exposure to pollution, and by tracking air quality around them, cyclists , commuters , parents will also contribute to mapping air quality in their city. 长此以往,你会养成 更好的习惯,更少接触污染, 不仅如此,通过监测那些骑手、 通勤者和父母周围的空气质量, 我们也能构建出城市空气质量地图。

device:n.装置;策略;图案; community:n.社区;[生态]群落;共同体;团体;
And last summer, we sent early prototypes of our technology to 100 volunteers in London, and together they mapped air quality across 1,000 miles of sidewalk and 20 percent of all of central London. 上个夏天, 我们在伦敦将原型机 分发给100个志愿者, 他们的数据合起来,构建出了 横跨一千英里街道 和伦敦中央20%地区的空气质量图。
prototypes:n.原型;技术原型;雏型; volunteers:n.志愿者; v.自愿做; (volunteer的第三人称单数和复数) sidewalk:n.人行道;
So our goal now is to scale this work around the world, to crowdsource data so we can map air quality on every street, to build an unprecedented database so scientists can research pollution, 所以我们现在的目标 是把这张地图扩大到全世界, 收集大众信息,以采集 每一条街道的空气质量信息, 来构建一个前所未有的数据库, 这样科学家就可以研究污染,
