This obviously shows that pollution is affecting the world in a far more serious way than had been previously thought. Environmental pollution does not just affect the locality from which it originates but enters the atmosphere to join other locally produced pollution around the world which then becomes a global problem. Because the earth's atmosphere continually moves and revolves around the world, what seems to be just a problem in one area becomes a problem in a much bigger area. So this problem needs to be treated not only at a local level but at a global level too.
Of course, we should do what we can at home; but unless every country in the world joins forces to combat environmental pollution, no lasting solution can be found.
上图象征性地描绘了一个浓烟笼罩的头骨从一个巨大的烟囱中升起，以一种威胁的姿态覆盖着整个地球。下面的说明文字显示：环境污染。
这显然表明污染对全世界的影响比人们之前料想的要严重得多。环境污染不只是影响污染发源的地区，还进入大气层与世界其他地方产生的污染一起，最终成为一个全球性问题。因为地球的大气层围绕整个世界运动和旋转，所以貌似只是某一地区的问题就成了更大范围的问题。因此治理环境污染不仅需要地区层面的努力，还需要全世界的努力。
当然，在国内我们应该尽己所能；但是除非世界上的所有国家都携手防治环境污染，否则我们是找不到持久的解决办法的。
