What do you think about the exploitation of the ecosystems? I need to set up a discussion debate on this. Thanks!

The exploitation ecosystems hypothesis proposes that, in productive terrestrial ecosystems, primary production is high enough to support three trophic levels: plants, herbivores and predators. Predators depress herbivore populations, releasing plants from herbivore control and enabling them to increase in biomass — a community-level trophic cascade. In less productive ecosystems, however, herbivore populations are too small to support predator populations, so there are only two trophic levels, with herbivores regulating plant biomass. In extremely unproductive ecosystems, the productivity is too low to support more than the plant trophic level. The key to the exploitation ecosystems hypothesis is that it acts as though each trophic level consists of a single population, despite many different species being involved.
