I chose not to serve shark's fin at our wedding for environmental reasons. Defying tradition, said some guests. Now, more proof about the environmental impacts of overfishing shark: the New York Times today reported that besides devastating the populations of large sharks, it has also devastated the bay scallop fisheries on the U.S. Eastern seaboard. How does that work?
In the absence of large sharks, the researchers say, the smaller sharks, skates and rays that they feed upon have thrived. In turn, the study shows that as one of these middle links in the food chain, the cownose ray, has become more abundant, it has wiped out scallop beds in North Carolina.
Just another example of how humans wreak havoc on the ecosystem's balance.
