“可持续性”这一概念无疑具有某种直观的吸引力。任何既解决环境问题同时又促进人类健康的提议,至少经过推理论证后,是很少遭到异议的。但是,“可持续性”这个词(或者同样时髦的“可持续发展”)实际上是什么意思呢?这个问题并不象它第一眼看上去那么平凡,因为对此明显已有太多的定义(根据一个资料统计,至少有40个)。这些众多的意思和内涵表明该概念带有一定程度的不确定性。一、什么是可持续发展?解答这个问题,可以简单地求助于布伦特兰委员会(Brundt-land Commission)的意见,即“可持续发展”被认为是一种既满足当前需要又不损害后代满足他们自己需要的能力的这样一种发展体系。“可持续发展”这一概念明显意识到我们(特别是发达世界)以往的经济增长的形式在生态意义上不是“可持续发展的”。因此,对现存的生态系统 The concept of “sustainability” undoubtedly has some intuitive appeal.
