<b>Lost Ecosystem Services and Vanishing Ecological Roles.</b><br>Forest ecosystems in the tropics and subtropics are being quickly replaced by industrial crops and plantations. This provides large amounts of goods for national and international markets, but results in the loss of crucial <a href="https://en.wikipedia.org/wiki/Ecosystem_services" class="extiw" title="en:Ecosystem services">ecosystem services</a> mediated by ecological processes. In Borneo, the Dypterocarp forest, one of the species-richest in the world (F), is being replaced by oil palm plantations (G). These changes are irreversible for all practical purposes (H).
