Despite its lower biomass, the fynbos ecosystem has a higher value for the provisioning of benefits that depend on diversity, such as compounds for the pharmaceutical industry, c) High biomass, low variability cod-dominated marine system, d) Low biomass. high variability marine system after overexploitation of cod. Despite its lower variability, the cod-dominated system has a higher value for the provisioning of food, a benefit that is highly sensitive to amount (biomass). Furthermore, the provision of benefits often depends on the condition and extent of ecosystems - incorporating many species and their interactions amongst them and with their environment. Ocean fisheries provision, for example, is affected by the condition of coral reefs and mangroves. It is therefore proposed that the Review on the Economics of Biodiversity Loss should aim to address not simply the effects of the loss in variability, but also the effects of changes in amount, and in the condition and extent of ecosystems. To avoid confusion, throughout we use the expression wild nature to refer to this broader definition of biodiversity. By 'wild* we do not mean "pristine" (in which case it would apply to very few parts of the world); we mean 'non-domesticated' ( excluding for example livestock and crops). There are many ways in which wild nature contributes to human wellbeing. These have frequently been called 'ecosystem services', particularly in the context of the.
