原文呈现

Plan B: Life on Mars①？

In the 1960s and 1970s，the greatest fear was that the human race，and possibly all advanced② life forms on the planet，could be wiped out③ by nuclear④ missiles⑤，just at the push of a button.Today，however，environmental problems have taken over⑥ as the greatest risk to life on Earth.Scientists are thinking of ways to lower this risk，such as replacing coal and oil with forms of renewable⑦ energy.But they are also preparing for the worst: what can we do if the terrifying⑧ scenes in films such as The Day After Tomorrow happen in real life? What is our Plan B for Earth?

One option is to explore other planets to see if we could live on them.The most likely choice is Mars，which is relatively⑨ close to Earth and has an environment less hostile⑩ than that of other planets.Mars has fascinated people since ancient times，and today our interest in Martian exploration is greater than ever before.Films such as The Martian enjoy worldwide popularity⑪.More governments and organisations are making efforts to⑫ educate the public on the Red Planet，for example，the Mars Desert Research Station in the Utah desert of the US and the Mars Village in North­west China's Qinghai Province.

Since the 1960s，we have been sending unmanned⑬ spacecraft⑭ to Mars.Our probes⑮ have orbited⑯ the planet，sending back valuable data and stunning⑰ images.Our robots have explored the Martian surface，testing the soil and searching for resources，water and signs of life. Encouraged by discoveries over the years，space agencies⑱ of various countries are planning manned missions⑲ to Mars that could take place within the next 25 years.

There is no doubt that humankind is drawn towards Mars，with dreams of making it our second home.However，sending people there will require all the skill，courage and intelligence of the human race.While the Moon can be reached within days，it would take months to reach Mars，travelling through dangerous solar⑳ radiation.And even if the first settlers do reach Mars safely，they may not be able to return to Earth—ever.Staying alive will be a daily challenge，but as proved by the Biosphere 2 experiment，not impossible.As early as the 1980s，scientists were building Biosphere 2 in the Arizona desert.It consisted of a closed space in which people，animals and plants could live together.The “closed” concept meant that the space was designed to function with its own oxygen，food and water，needing nothing from the outside world.Although the two­year experiment was not a success，it did provide us with a better understanding of how humans might be able to live on another planet.More recently，scientists have succeeded in growing a variety of plants in an environment similar to that on Mars.That definitely is a big step forward.

For now，human settlement of Mars is still decades away.In the meantime，scientific research shows that the planet Earth is getting warmer.This change is being caused by human activity and is having a terrible effect on the biosphere.Until we are finally able to live on another planet，we need to take much better care of our own.Right now，it's the only one we have！

B计划：在火星上生活？

在20世纪60年代和70年代，最大的恐惧是只要一按按钮，人类就可能和地球上所有的高级生命形式，一起被核导弹消灭。然而今天，环境问题已经变成地球上的生命面临的最大威胁。科学家们正在思考降低这一风险的方法，例如用各种可再生能源替代煤炭和石油。但他们也在做最坏的打算：如果《后天》等电影中的恐怖场景发生在现实生活中，我们该怎么办？对地球，我们的B计划是什么？

一种选择是探索其他星球，看看我们能否在上面生活。最有可能的选择是火星，它离地球相对较近，环境不像其他行星那么恶劣。火星自古以来吸引着人们，我们现在对探索火星的兴趣比以往任何时候都更浓厚。像《火星救援》这样的电影在全世界都很受欢迎。越来越多的政府和组织正在努力对公众进行有关“红色星球”的教育，例如美国犹他州的火星沙漠研究站和中国西北部青海省的火星村。

自20世纪60年代以来，我们一直在向火星发射无人飞船。我们的探测器已经绕火星轨道运行并发回了宝贵的数据和令人惊叹的图像。我们的机器人已经探索了火星表面，测试了土壤并且在寻找资源、水和生命的迹象。受到多年来这些发现的鼓舞，各国航天机构正计划在未来25年内进行载人飞船登陆火星的任务。

毫无疑问，人类对火星充满兴趣，梦想着把它变成我们的第二个家园。然而，把人类送上火星将要求人类具备所有的技能、勇气和智慧。到达月球只需要几天的时间，而到达火星却需要数月的时间，并要穿越危险的太阳辐射。而且即使第一批开拓者安全抵达火星，他们可能永远无法再回到地球。活着将会成为一个日常挑战，但正如“生物圈2号”实验所证明的这也并非完全不可能。早在20世纪80年代，科学家们就在亚利桑那州的沙漠中建造了“生物圈2号”。它由一个封闭的空间组成，人、动物和植物可以在里面一起生活。“封闭”的概念意味着这个空间被设计成依靠自身的氧气、食物和水来运作，而不需要外界的任何东西。尽管为期两年的实验并不成功，但它确实让我们更好地了解了人类如何能够在另一个星球上生活。最近，科学家们成功地在类似火星的环境中种植了各种各样的植物。这无疑是向前迈出的一大步。

到目前为止，人类要在火星上定居还需要几十年的时间。同时，科学研究表明地球正在变暖。这种变化是由人类活动引起的，而且对生物圈产生了严重的影响。在我们最终能够生活在另一个星球上之前，我们需要更好地保护好我们自己的星球。现在，它是我们唯一一个赖以生存的星球！
