This already well underway. The book & film "End of the Line" is well worth a read. Also the massive disruption of the eco-system by removing large numbers of species has un-predictable knock on effects - for example massive numbers of jelly fish in some areas and of course the algae/plankton population explosions which in turn effect the ecosystem to the detriment of other species.
