A world government would enhance the probability of mitigating global environmental problems  A world government would enhance the probability that effective means will be developed and implemented toward ameliorating the global problems of resource depletion and environmental decay. In a world divided into a host of jealously independent and self-righteously sovereign nations, national leaders tend to point the finger of blame for these problems at other nations, and to resist international efforts toward resource conservation and environmental preservation. As the mutual accusations and recriminations go on and on, the problems are left to fester. If a world government existed, it might muster sufficient respect and possess sufficient authority to enable the nations to arrive at a workable consensus on how to share equitably the short-term costs and inconveniences necessary to securing long-term sustainability of resources and preservation of environmental quality.
