There is much to say. We allow millions of gallons of crude oil and dispersants into the sea and it eventually evaporates, at least those components of lighter specific weight. It has an effect no matter where we put it - when it is not underground in its natural reservoirs. Do we believe that millions of gallons of this stuff released onto the earth really has no chance for inestimable effect?
How do we explain the mass death across species? There may be a connection more profound and real between living beings than was ever before realized. Here, when one species has encountered particularly difficult changes in their environment, the distress may be passed to another by ways which ego-centered, dollar-driven humans can not understand. They have the feeling that their place in the world and time has passed, so they experience a common exit.
And, perhaps, so little time to say it.
