阳光、空气、水,对于人类,三者不可缺一。说阳光、空气重要者多,说水重要者,似乎较少,也似乎往往说得不够份量。 “万物生长靠太阳”。不错。然而,难道不也应当大唱特唱“万物生长靠水”么? 是空气包围着并保护了地球,使人类得以生存繁殖,这是我们不应忘记的。然而,若是没有了水,人类能够在地球上出现么? 天文学家还没有发现地球之外任何一个可以有生命存在的星球,也即还没有发现任何一个拥有足够的水以培育生命的星球,科学家告诉我们:地球上的生命是从大海大洋里首先萌生的。 我们拥有水。我们何等幸福!

Astronomers have yet to find any living planet on Earth, that is, have not found any planet that has enough water to nurture life, scientists Tell us: Life on earth is the first to emerge from the ocean. We have water. How happy we are!
