我们越来越多地通过功利主义的视角来看待自然，这导致我们试图衡量和管理物种、栖息地和生态系统提供的服务。令人惊讶的是，我们往往只考虑生态系统的积极价值，即它们的生态系统服务。除了提供我们的食物和水，大自然还杀死我们，主要是通过疾病。如果我们要有效地管理地球，我们还需要管理物种、栖息地和生态系统，以最大限度地减少这种对生态系统的破坏。我考虑了我们所知道的一种伤害的空间模式，病原体的流行，以及栖息地的变化是如何影响它的。我考虑了栖息地变化对病原体流行的影响，从而对生态系统造成了破坏。归根结底，我们需要权衡特定生态系统、栖息地和物种的成本和收益--考虑利弊。要做到这一点，我们需要了解比目前更多的关于生物群的知识。
Increasingly, we view nature through a utilitarian lens that leads us to attempt to measure and manage the services that species, habitats and ecosystems provide. Surprisingly, we have tended to consider only the positive values of ecosystems, their ecosystem services. In addition to providing our food and water, Nature also kills us, primarily through disease. If we are to effectively manage the terrestrial Earth, we need to also manage species, habitats and ecosystems so as to minimize such 'ecosystem disservices'. I consider what we know about the spatial pattern of one disservice, pathogen prevalence and how changes in habitat influence it. I consider the effects of habitat changes on pathogen prevalence and, consequently, ecosystem disservices. In the end, we need to weigh both the costs and the benefits of particular ecosystems, habitats and species - to consider the bad with the good. Doing so requires that we learn much more about the biota than we currently know.
