水是一切有机体的主要组成部分，全球动植物和40亿人体内含有约11200亿吨水。人类社会依赖水而生存发展。古代，人类对水取利避害，适应水而生存；近代，人类对水兴利除害，兴建工程，开发水利，控制水害；现代，随着社会和生产的发展，地球上可资利用的水日趋短缺，水体受到污染，严重影响人类生存的环境，人类逐渐认识到水是一种重要资源和环境因素，从而在更高的水平上开始对水开展了新的兴利避害活动。
世界气象组织1996年初指出：缺水是全世界城市面临的首要问题，估计到2050年，世界2/3以上的人口将生活在城市，而全球有46％的城市人口缺水，必须平衡社会经济发展和城市淡水供应管理二者之间的关系，进行水资源的储存、输送和管理的大规模工程建设。

人的身体就好比一台机器，机器缺了油就会停止运转，人的身体如果没有维生素及蛋白质、脂肪、糖、钙、磷、铁等多种营养元素来源源不断补充，就难以生存。当然，上述的营养元素大部分可以从鸡、鱼、肉、蛋或水果中得到，可是从我们目前的生活水平来看，人体需要的维生素主要还是来自蔬菜。
什么叫蔬菜呢?简单地说，蔬菜就是可以做菜吃的草本植物。它以十字花科和葫芦科的植物居多。我们常吃的，如白菜、菠菜、芹菜、胡萝卜、黄瓜、辣椒、西红柿等，统称之为蔬菜。它们都含有丰富的营养，但又有各自的特点--各种维生素的含量不同，就胡萝卜素来说，同样都是100克蔬菜，菠菜含有3.87毫克，胡萝卜含有3.67毫克，鲜蒜头则是空白。
我们在日常生活中，不但要多吃蔬菜，更需要了解它们。这是因为人体一旦少了某一种营养元素，就会导致疾病的发生。你有贫病吗?请经常食用菠菜，因为菠菜含有不少的维生素B6,而维生素B6可以起到医治贫病的作用。此外，它还含有为数不少的其他维生素B以及钙、磷等营养成分。你的胃口不佳，食欲减退吗?就请食用适量的鲜蒜头，因为它含有维生素B1。据介绍，每100克的鲜蒜头就有0.24毫克的维生素B1，而它的功能是帮助消化的。因此，适当地吃些鲜蒜头就可以增加食欲。你想使自己的伤口尽快愈合吗?请适量地吃些辣椒。因为辣椒含有数量惊人的维生素C.据科学统计，每100克的辣椒就含有185毫克的维生素C，它比其他蔬菜的含量要多好几倍。你患有夜盲症或干眼吗?就请常吃些胡萝卜。因为它含有比较多的胡萝卜素，而胡萝卜素在人体这个特定的环境中，可转化成维生素A,这对夜盲症、干眼病有很好的疗效。以上这些都说明了蔬菜是良药。
古人说：问渠哪得清如许，为有源头活水来。诗句告诉我们，水清，在于有源头活水，同样道理，人体健康，也必须靠多种维生素来补充。因此，即使是一个身体健康的人，在日常生活中也必须尽可能吃多种蔬菜。然而有些人不吃带药味的蔬菜，如芹菜;也有一些人不吃带辣味的，如辣椒;更有一些人不吃带酸味的，如西红柿。另外，还有一些人对合口味的蔬菜，连吃数餐、数日，甚至到吃厌为止。这些都是挑食、偏食的弊病，它不能提供肌体所需的多种维生素，应该尽量克服。
蔬菜是人们一日三餐中不可缺少的，如能食用多样化，那得到的将是健康长寿。
