Environment problem is nowadays a buzzword in many people?s mind. Unlike other factors, from a politician, a philosopher to a war, this is an enormous international problem, affecting any country regardless of boundaries. Human beings are hence urged to join together in this common struggle for life.
Neither a press-group nor a dramatic event can attract such widespread concerns as an environmental issue.
A politician, with all his credentials, for example, can at most affect citizens in his country through legislations and policies. Meanwhile, the declining environment may soon affect countless people from different countries by no words but a number of hazardous actions.
A philosopher, in another instance, is likely to receive both believers and skeptics for his theories and discoveries. The results of natural disasters, on the other hand, are true and direct enough to convince any conservative person.
