...ety in the form of fishing and tourism. One recent estimate concluded the world's reefs provide annual net economic benefits of $30 billion. But more than 10% of the reefs have been destroyed by human activity, and an additional 16% were extensively damaged in 199798 alone by coral bleaching during a major El......n Americanlandscape, which was used to compare and estimate the reductionof NPP due to current urban-land transformation. For the continental United States, when compared to the pre-urban landscape, modern cities account for a 1.6 percent annualdecline in NPP. This loss offsets the gain in NPP of 1.8percent a......rmously greater than is currently recognized. They estimate that since the onset of intense exploitation in the Gulf of Mexico in the 1950s, the pelagic shark assemblage has declined by over 80%, and the oceanic whitetip shark, initially the most common species, by over 99%.
