The Baiji, or Yangtze River Dolphin, appears to be the first cetacean \<a href="http://en.wikipedia.org/wiki/Baiji"" target="_blank" rel="noopener noreferrer">driven to extinction by man. No man is an island,
Entire of itself.
Each is a piece of the continent,
A part of the main.
If a clod be washed away by the sea,
Europe is the less.
As well as if a promontory were.
As well as if a manner of thine own
Or of thine friend's were.
Each man's death diminishes me,
For I am involved in mankind.
Therefore, send not to know
For whom the bell tolls,
It tolls for thee.
