    I read the following article today on Yahoo News! and was appalled at the implications... We humans are polluting our own back yards in manners not often noticed until it's too late. The lowly bivalve mussel has long been placed on the "Do Not Eat" list from many waters, but who tells the fish not to eat them?

    At the middle of the food chain, these simple creatures filter the water and remove their food, and a host of other things like pollutants. When they're gone, poisioned by the very thing that they eat, what will take their place?;_ylt=Al.btMtjofmTFDmkNwKDTioDW7oF

    Mussels may start disappearing from restaurant menus as species increasingly become extinct or endangered by human activities, scientists say.

    North America has historically had a very diverse community of freshwater mussels—providing ample supplies for diners. But populations have been on the decline for the past few decades, and mussels now are one of the most endangered groups of animals on the continent, according to the U.S. Fish and Wildlife Service.

    Humans are primarily responsible for the disappearance of mussels through water pollution and changes to their physical habitat wrought by the construction of dams, dredging and the introduction of exotic species.
