The argument for "monetizing"—or putting a monetary value on—ecosystem functions may be stated thus: Concern about the depletion of natural resources is widespread, but this concern, in the absence of an economic argument for conservation, has not translated into significant conservational progress. Some critics blame this impasse on environmentalists, whom they believe fail to address the economic issues of environmental degradation. Conservation can appear unprofitable when compared with the economic returns derived from converting natural assets (pristine coastlines, for example) into explicitly commercial ones (such as resort hotels). But according to David Pearce, that illusion stems from the fact that "services" provided by ecological systems are not traded on the commodities market, and thus have no readily quantifiable value. To remedy this, says Pearce, one has to show that all ecosystems have economic value-indeed, that all ecological services are economic services.Tourists visiting wildlife preserves, for example, create jobs and generate income for national economies undisturbed forests and wetlands regulate water runoff and act as water—purifying systems, saving millions of dollars worth of damage to property and to marine ecosystems. In Gretchen Daily’s view,monetization, while unpopular with many environmentalists, reflects the dominant role that economic considerations play in human behavior, and the expression of economic value in a common currency helps inform environmental decision-making processes.

    一段分为4个层次 1、解释monetizing,是在缺乏环境经济论据的情况下,尽管对自然资源枯竭很担忧,但是这种担忧并没有转化为自然保护的进展,意识是在缺乏保护经济的情况下,担忧资源枯竭也是白担忧,所以要重视保护的货币化。 2、评论家的观点:把僵局归咎于环境保护论者,认为他们没有处理好环境退化的经济问题,同时指出资源保护就是无利可图的 3、DP 又解释说“认为资源保护无利可图”这种说法是一种错觉,这种错觉是因为生态系统提供的服务没有量化价值(从而导致环境“无利可图
