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. , 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. Abelardo Colon Nieves Science. This empirical work supports long-standing theory about the role of top-down forcing in ecosystems but also highlights the unanticipated impacts of trophic cascades on processes as diverse as the dynamics of disease, wildfire, carbon sequestration, invasive species, and biogeochemical cycles.

Patterns of extinction risk in trophic groups across habitats. We live in the Anthropocene, as some scientists have come to call our new geologic era.The term acknowledges the fact that human beings—nearly 7 billion strong and growing—have so much influence over the life, geography and even chemistry of planet Earth that we’re now essentially responsible for the whole show. unanticipated impact    A. Estes and coauthors highlight the far-reaching changes to ecosystems that result from the loss of apex consumers. NEW YORK (July 20, 2011) – The loss of large predators in the wild may be humankind’s most pervasive influence on nature, according to Wildlife Conservation Society Conservationist Joel Berger.
