Table 6 gives an overview of the environmental problems that have been modeled. Notice that many models have been focusing on a problem for a specific ecosystem and are therefore included in both table overviews. There are of course also models that focus on a specific problem without considering the ecosystem, for instance, fishery, the greenhouse effect, and acid rain, and models that model a specific ecosystem without considering a specific problem, for instance, element cycling in an arctic ecosystem or in a wetland. Table 6 uses the same classification as Table 5.
