《美國頁岩油熱潮不再》
目前美國每日產油780萬桶,是25年來的最高記錄。來自頁岩的 原油降低了美國對進口石油的依賴,令該國處於1989年以來最接 近能源自主的狀態。國際能源總署(IEA)去年預測,到2020 年,美國將超越沙地阿拉伯,成為全球最大的產油國。
但美國當前的產油量能否持續,已經成為爭議話題。地質學家暨全球可持續發展研究總裁曉士研究過頁岩井的壽命周期。他表示: 「紅心皇后症越來越嚴重。產量越高,你就需要越多油井來彌補產量 之衰退。」
在北達科他州的巴肯頁岩區,一口名為「Robert Heuer 1-17R」的油井2004年5月投產時,出油量為2358桶。 這產量證明巴肯的石油鑽探生意有利可圖,引發北達科他州的石油開 採熱潮。該油井的產量第一年下跌69%。石油地質學家伯曼指出: 「我認為頁岩熱潮是一場退休派對而非一場革命,這是最後一口氣。 」

http://en.wikipedia.org/wiki/Red_Queen_hypothesis
The Red Queen hypothesis, also referred to as Red Queen's, Red Queen's race or The Red Queen Effect, is an evolutionary hypothesis which proposes that organisms must constantly adapt, evolve, and proliferate not merely to gain reproductive advantage, but also simply to survive while pitted against ever-evolving opposing organisms in an ever-changing environment. The Red Queen hypothesis intends to explain two different phenomena: the constant extinction rates as observed in the paleontological record caused by co-evolution between competing species[1] and the advantage of sexual reproduction at the level of individuals.[2]
The original idea of the Red Queen hypothesis (macroevolutionary) was given by Leigh Van Valen in order to explain the “Law of Extinction”.[1] Leigh Van Valen showed that in many populations the probability of extinction does not depend on the lifetime of this population. In addition, the probability of extinction is constant over millions of years for a given population. This could be explained by the coevolution. Indeed, an adaptation in a population of one species (e.g. predators, parasites ...) may change the selection pressure on a population of another species (e.g., prey, hosts), giving rise to an antagonistic coevolution. If this occurs reciprocally, a potential dynamic coevolution may result.[3] The phenomenon's name is derived from a statement that the Red Queen made to Alice in Lewis Carroll's Through the Looking-Glass in her explanation of the nature of Wonderland:
Now, here, you see, it takes all the running you can do, to keep in the same place.[4]In another idea (microevolutionary), the Red Queen hypothesis is used by Bell to explain the evolution of sex,[2] by John Jaenike to explain the maintenance of sex [5] and W. D. Hamilton explain the role of sex in response to parasites.[6][7] In all cases, sexual reproduction confers species variability and a faster generational response to selection by making offspring genetically unique. Sexual species are able to improve their genotype in changing conditions. Consequently co-evolutionary interactions, between host and parasite for example, may select for sexual reproduction in hosts in order to reduce the risk of infection. Oscillations in genotype frequencies are observed between parasites and hosts in an antagonistic coevolutionary way without necessitating changes to the phenotype.
