FAITH ARGUES THAT OUR APPROACH TO BI0-diversity conservation, which focuses on people's interest in the benefits of ecosystem services, may deprive us of future, unanticipated benefits. This claim is misplaced. In our Policy Forum, we argue that conservation goals should reflect the benefits we get from biodiversity. The argument is not conditional on the type or timing of benefits delivered. We agree that it is not just biodiversity's value in producing marketed commodities that matters. Its indirect value in supporting ecosystem services is often more important (7), and its potential value to future users (option value) and to future science (quasi-option value) has been recognized as the most important of all for at least three decades (2-4).
