Yeah,

In NYC before people were messing up the environment just by the nature of building a huge city, there were billions of oysters all around amd the water was super clean.

Then they harvested and ate all the oysters, and the waters became very polluted.

Look at the size of this pile of oyster shells from 1912

Those are people standing on the pile
