In 1968 an American ecologist, Garrett Hardin, published an article entitled “The Tragedy of the Commons”. He argued that when a resource is held jointly, it is in individuals‟ self-interest to deplete it, so people will tend to undermine their collective long-term interest by over-exploiting rather than protecting that asset. Such a tragedy is now unfolding, causing serious damage to a resource that covers almost half the surface of the Earth. The high seas are a commons.词汇突破：

解释：一个向众人开放的牧场，在其中每个牧羊人的直接利益取决于他所放牧的牲畜数量的多少。由于在缺乏约束的条件，当存在过度放牧问题时，每个牧羊人虽然明知公地会退化，但个人博弈的最优策略仍然只能是增加牲畜数量，久而久之，牧场可能彻底退化或废弃。这就是“公地悲剧”。
