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.

    要成为an“ecological service"的例子要满足以下两个条件:
    1、是生态服务,关于生态保护的服务措施(例如自然保护区这种,不是工厂、公司)
    2、能够创造出经济价值(例如可以带来就业或者经济收入)

    问下面哪个例子可以作为ecological service的例子?
    
    关于ecological service,我们可以看看后面的for example怎么说?Tourists visiting wildlife preserves, for example, create jobs and generate income...我是这么认为的,wildlife preserves是一种ecological service,就是你保护生态,建立自然保护区是一种ecological service,建立了之后人们可以去visit,就会对旅游业有所发展,会创造就业和产生income,毕竟旅游业是第三产业,属于economic的范畴,就是指economic services。因此,ecological services是指可以创造出经济价值的生态服务(例如生态旅游业ecotourism)
