A little cause for hope and a lot of good eating
Oysters have been around a long time, in the vicinity of 500 million years.
Arriving somehow in the Chesapeake, which came into being only 35 million years ago, oysters made themselves at home. In the prehistoric broth, temperatures were moderate, oxygen abundant and food plentiful for the filter-feeders. In synergism over the eons, thriving oysters both kept the Bay clean and made welcoming reef homes for many species seeking shelter and prey. For immobile creatures, oysters got a lot done.
