Yet, when we look carefully at various disasters, we also discover that they all have their long-range causes, in which humans always play a part. That is to say, at a deeper level, when people interact with nature, nothing is completely accidental. People have the responsibility to do what they can to prevent or minimize the damage from even the most unpredictable disaster.
然而當我們正視、檢驗災難的種種，我們也會發現，深遠一點來看，人類與大自然相依相存，沒有一件事情是完全的意外，即使是最不可測的天災，人類有責任也有能力防止。
