" species have the potential to sink or save the ecosystem, depending on the circumstances. Knowing that we must preserve ecosystems with as many of their interacting species as possible defines our challenge in no uncertain terms. It helps us to focus on the ecosystem as an integrated functioning unit, and it deemphasizes the conservation of single species. Surely this more comprehensive approach is the way to go. "
