Conservation biology does focus on the benefits of biodiverse ecosystems to individual humans. In particular it models the way in which reduced species numbers will adversely impact us by degradation of ecosystem services like water cycling, water and air purification, pollination, coastal and inland erosion prevention, carbon storage, and the loss of potential new foods, medicines, materials, and a very wide range of biotechnologies. It's the louder voices in our culture and media with oppositional interests that successfully mischaracterize and drown out what conservationists say.
