The uses of experimental ecosystems.
The experiments conducted so far with large experimental ecosystems have probably taught us more about the general ecological interactions in such systems than about subtle long-term effects of pollutants. This knowledge is not only valuable in its own right but may be more useful in an indirect rather than a direct way, in understanding the robustness of these systems and so evaluating the general effects of stresses.
