生存和毁灭
地球上生命的历史一直就是一部生物与其环境相互作用的历史。在很大程度上,地球上动植物的形态以及习性都是由外部环境所塑造的。考虑到地球上生命存在的整个时间,相反作用——即生命对其周围环境的实际改变作用一却相对很小。只有在当前这个世纪才有一个物种——人类,获得了强大的力量,改变了其所生存的世界的自然状态。
在过去的l/4世纪中,这种力量不仅日趋强大,而且其性质也发生了变化。在人类破坏环境的种种行为中,最令人担忧的是人类向大气、土壤、河流以及海洋中排放危险甚至致命物质,而当今这种污染在很大程度上是无法挽救的。在当今这种对环境的普遍污染中,化学制品与辐射狼狈为奸,改变着地球的自然状态,也就是改变着地球上生命自然状态。
地球历经了许多亿年才创造了栖息其上的生命。经过了一定时间——不是以若干年计算而是以上千年计算的时间——生命开始适应环境,并形成了一种与环境的平衡。但是在当今世界,时间这一因素已经没有了。
我不是说人类决不能使用化学杀虫剂。我要说的是,我们不分青红皂白地将这些有毒的、具有强大生物功能的化学制品,交给了那些对这些制品的潜在危害基本上或者完全无知的人去使用。我们使众多的人接触这些有毒物质,却没有征得他们的同意,并常常将他们蒙在鼓中、我还要说的一点是,我们允许使用这些化学制品,却事先很少或者根本没有调查它们对土壤、水、野生生物以及人类自身造成的影响。我们缺乏对万物赖以生存的自然界生态统一的关心,对此,我们的后代是不可能原谅的。
