As sad as these things are... one needs to also accept, that as capable as we are of changing our environments, from transportation, to air conditioning, we do not control all the things. We have and continue to over-fish in a lot of places, and I have deep concerns over farmed fish and the impact of less than natural foods on our own health.

A lot of the changes to the waters is well outside human control... there's a huge balance of factors at play from the earth, moon and sun. We don't control these things... and to what impact we can/do, I'm not sure that anything we might do may not have unintended consequences that are materially worse.

We can definitely do some things, but the level of internalized and externalized guilt that people in and outside these discussions seem to carry and put on others isn't at all healthy in and of itself.
