The loss of these animals may be humankind’s most pervasive influence on nature. STONY BROOK, NY–"Trophic Downgrading of Planet Earth," a review paper that will be published on July 15, 2011, in the journal Science, concludes that the decline of large predators and herbivores in all regions of the world is causing substantial changes to Earth’s terrestrial, freshwater, and marine ecosystems. Trophic Downgrading of Planet Earth. AU - Estes, J.A. Although such losses are widely viewed as an ethical and aesthetic problem, recent research reveals extensive cascading effects of their disappearance in marine, terrestrial, and freshwater ecosystems worldwide. A recent article in Science describes how the widespread removal of large apex predators from natural ecosystems is one of the most pervasive influences humans have had on nature, particularly because of unexpected impacts from trophic cascades such as the one described above.
