第六单元

从理想上说，人们希望知道地震什么时候发生，破坏程度会如何。
在日本和中国，人们长期以来一直相信地震是可以预测的。
在日本，科学家在陆地上和海洋中铺设电线，以监测它们的运动。
而中国人的传统做法是观察动植物以获取地震的警示信号。
例如，中国人注意到，地震之前母鸡的行为会有所异常：它们夜晚不肯进笼。
他们还注意到，蛇会爬出地穴而冻死，狗会狂吠不已，甚至那些平常很安静的狗也会叫个不停。
日本的阪神地震发生之前，有报告说大批鱼群游到了水面。
有些鸟，如鸽子，也显得特别聒噪，据说地震前它们飞行的方式也与往常不同。
也许最有趣、也最容易测量的，是地震前地下水发生的化学变化。
实验数据似乎表明，地震前地下水中氡的含量会增高。

人们还希望能够预防地震会造成的重大财产损失。
要知道，多数在地震中丧生的人都是被倒塌的建筑物砸死的。
所以，具有抗震能力的房屋结构是关注的重点。
钢似乎是最佳的建材，但一旦被焊接成僵硬的结构就不行了。
许多新式结构都采用了一种新型的钢接合方法，即I形接合，它看来是最耐用的一种接合。
这种钢接合在移动时不会断裂。
同样，为了预防财产损失，建筑师如今设计楼房时会使房屋的支柱和横梁力度相等，而垂直支柱则深深插入坚实的地基中。
此外，许多新型房屋都采用了较轻的屋顶和坚实的墙壁。
高架桥的水泥柱先前只是在内部有钢筋，如今外面也包上了钢板。

除了设法改善建筑结构外，地震频发区的人们也需要为可能发生的大地震做好防备工作。
他们应当定期检查和加固房屋，将重物放在低处，将橱柜和柜子贴墙放置，加固房门以防地震时意外脱开。

除做好房屋的防震外，这些地区的人们还需要为自身做些防备。
他们应该在家里和工作地储备些水和食物。
最好每人储备几加仑水。
储备一些可以净化水和消灭病菌的东西也很重要，这样就可以安全地饮用其他来源的水了。
每人准备一周的食物。
地震救生储备还包括无线电接收器、手电、备用电池、急救用品、铁锹、帐篷、绳子和保暖衣物。
此外，专家们还提出了以下建议：

手边备有灭火器。
应该在住处、工作场所和汽车里(如果你有车的话)都存放一个。
灭火器应该是可以扑灭任何火灾的那种。
有必要的话，准备一些能关闭煤气和自来水管道的特制工具。
准备一个备用的户外烹调和取暖用具，可以准备一个便携式露营灶和几小罐煤气。
在住处、工作场所和汽车里放一双厚重、舒适的鞋或靴子。
发生地震时会有大量的玻璃碎片。
轻便的鞋子不能像厚重的鞋子那样保护好你的双脚。

每个家庭都需要制定地震应急计划。
如何让一家人在地震的混乱中安全离开？
大家应该商定一个地震区外的会合点——可能是在几英里外的某个市镇。
同样，协商好地震时家人的联络方式也很重要。
地震若发生在大城市，市里的许多电话线路很可能中断，
剩下的为数不多的可用线路会很忙，因为灾难之后自然会有许多电话，要从市里的一个地方打到另一个地方会很困难。
但可能通向市外的电话是通的。
明智的安排是，让所有的家人都给一个住在一百多英里之外的朋友或亲戚打个电话，以报平安。

尽管科学家们仍无法预测地震，但对地壳中的大板块如何移动，板块间的压力如何，地震如何发生，某地区发生地震的一般概率为多少，他们了解得越来越多。
在不久的将来，精确预测地震将成为可能。
然而，即使可以预测，居住在地震频发区的人们还是应尽力预防灾难，办法是建造能够抵抗地表运动的房屋，同时做好个人准备。
在挽救生命和防止家庭损失方面，这些预防措施会发挥很大的作用。
教育人们如何在地震中求生，应该是所有政府规划和地震研究项目的重点所在。

人的感觉是相对的。

和人相比，一棵树看起来很大。
可是将树和山相比，大树就显得小了。
换言之，自然界的事物是大是小，是新是旧，仅仅是就其所涉及的标准和比较而言的。

人的一生中，不会有很多东西发生变化。
连树也活得比人长，而地球本身就更是个老寿星了。
地球约形成于50亿年前，源于一团循环旋转的尘埃和诸如氢、氮之类的气体。
10亿年后，这个星球冷却下来，于是形成了大陆和大片的水域。

大约35亿年前，又发生了一次巨变。
海洋中开始孕育一个巨大的生物体系，包含各种各样相互依赖的生命形态。
在地球这个有生命的星球上，最早的动物是原始海洋动物。后来，在大约5亿年前，这些海洋动物进化成了甲壳动物。
7,000万年后，首次出现了鱼。
而后，大约4亿年前，出现了昆虫。
又过了2亿年，恐龙和第一只哺乳动物开始在地球上行走。
大约2亿年前，温血动物开始在天空中飞翔——它们是最早的飞鸟。
5,000万年后，鸟和哺乳动物都有了稳固的形态。
科学家们认为，大约300万年前，原始人类开始在地球上行走。
这时生命开始兴旺起来。

就地球上生命的进化而言，人类是姗姗来迟者。
然而，尽管在地球上的时日尚短，人类却已给地球表面带来了巨大的变化——这些变化与人类占据地球的短暂时间相比，是远远不成比例的。

人类企图控制资源

与地球上其他物种相比，人类更能控制其周围的环境。
由于智力与手工技能的结合(手工技能使得人类能够制造和使用工具)，人们已经发现了诸多利用地球动植物资源、矿产资源、燃料和许多其他物产和资源的方法。

随着地球上人口的增加，人类依靠土地资源生存变得越来越困难。
土地的总量是有限的。
虽然使用拖拉机等机械和施用化肥可以提高农业产量，但是土地最终所能产出的粮食只有那么多，不会再增加。
随着人口越来越多，人类的消耗也越来越多。
很明显，地球上某些地区人口已经饱和；在这其中的许多地区，未来的人口增长肯定会带来更多的贫穷和苦难。
然而，富裕国家的人们所使用的能源在比例上远远大于贫穷国家的人们。
他们毫无节制地使用这些资源，因此也造成了大量的浪费。

人类只是这个星球上所有生物的一小部分。
而这一小部分却造成了不可再生资源的流失。
比如说，地球上的水量是有限的，这些水通过自然作用得到净化。
但这些过滤水的自然作用通过去污仅能净化一定量的水。

同样，地表之下只能找到储量有限的石油。
石油是一种珍贵的资源。
难道人们应该为生产汽车用油而耗尽石油资源吗?
难道为了控制整个地球，令生活舒适，人类就要用尽生存所需的所有资源吗?

自然界的平衡

所有自然体系都趋向于在各种对立因素或力量中保持平衡。
而人类活动能够引起或加速自然体系中的永久性变化。
一处小火带来的烟不会危害环境，
因为自然净化作用会将空气中的烟尘清除。
但是，在过去的两个世纪中，从千万家工厂排放出的烟尘已大大加剧了全球大气的污染程度。
要清除这些烟尘已超出了自然作用的保护能力。
森林已不能及时清洁空气。

尽管人口迅速增长，工业快速发展，还是有一些人类群体——常常是居住在偏远地区的人们——能与地球和睦共处。
这些人从未改变过他们祖先的生活方式。
他们被称为土著，保留着历代不变的生活方式。
他们的许多文化价值观念和生活方式都包含向地球归还资源的做法。

人口的增长带来了粮食短缺、空气质量降低、天气状况变化等问题。
是什么在破坏雨林、土壤和海洋?
是什么造成了雨水穿过污染的大气时形成的酸雨?
为什么会有全球变暖的威胁?
所有这些恶果都源于对资源的过度使用和人类对环境的强行控制。

从20世纪初起，各强国竞相利用地球资源。
他们渴望成为帝国的贪欲造成了地球资源被滥用。
如今，全世界的人都在忍受这种滥用所带来的问题。
由于不再无视地球罹难的根源，人们正在寻求各种方法来治疗它，把自己取走的东西归还给地球。
从前人类只会利用地球，
如今每个人都必须保护地球，保护这个身处险境的星球。
