■感言
1990年2月14日，旅行者1号太空船，距地球40亿英里外（64亿公里外）拍摄的照片中，地球只是小小的一点。
（当时，旅行者一号，完成了主要任务，
离开太阳系的旅行者1号被NASA（美国国家航空航天局）命令转动相机，
最后拍了一张横跨了广阔空间的地球照片）
现在是4月23日，这张照片距今已经有30年了，
我们人类在近几百年内，技术突飞猛进，取得了惊人的进步。
尤其是这30年来，更为迅猛，小时侯，看动画片“星际迷航”中的视频通话，早已经实现。
登山远望、畅游在大海之中，会感受到自己的渺小，
而观看这张照片看，地球就犹如宇宙中的一粒尘埃，在宇宙之中显得如此渺小。
我们只有一个家园，地球。

我们成功地（从外太空）拍到这张照片，细心再看，你会看见一个毫不出奇的小点。再看看那个光点，它就在这里。那是我们的家园，我们的一切。你所爱的每一个人，你认识的每一个人，你听说过的每一个人，曾经有过的每一个人，都在它上面度过他们的一生。我们的欢乐与痛苦聚集在一起，数以千计的自以为是的宗教、意识形态和经济学说，所有的猎人与强盗、英雄与懦夫、文明的缔造者与毁灭者、国王与农夫、年轻的情侣、母亲与父亲、满怀希望的孩子、发明家和探险家、德高望重的教师、腐败的政客、超级明星、最高领袖、人类历史上的每一个圣人与罪犯，都住在这里——一粒悬浮在阳光中的微尘。
在浩瀚的宇宙剧场里，地球只是一个极小的舞台。想想所有那些帝王将相杀戮得血流成河，他们的辉煌与胜利，曾让他们成为光点上一个部分的转眼即逝的主宰；想想栖身于这个点上的某个角落的居民，对别的角落几乎没有区别的居民所犯的无穷无尽的残暴罪行，他们的误解何其多也，他们多么急于互相残杀，他们的仇恨何其强烈。
我们的心情，我们的妄自尊大，我们在宇宙中拥有某种特权地位的错觉，都受到这个苍白光点的挑战。在庞大的包容一切的暗黑宇宙中，我们的行星是一个孤独的斑点。由于我们的低微地位和广阔无垠的空间，没有任何暗示，从别的什么地方会有救星来拯救我们脱离自己的处境。
有人说过，天文学令人感到自卑并能培养个性。除了这张从远处拍摄我们这个微小世界的照片，大概没有别的更好办法可以揭示人类妄自尊大是何等愚蠢。对我来说，这强调说明我们有责任更友好地相处，并且要保护和珍惜这个淡蓝色的光点——这是我们迄今所知的唯一家园。

英文原文：
From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar" every "supreme leader," every saint and sinner in the history of our species lived there– on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that in glory and triumph they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Our posturings, our imagined self-importance, the delusion that we have some privileged position in the universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity– in all this vastness– there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known, so far, to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment, the Earth is where we make our stand. It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale blue dot, the only home we've ever known.
