Mercury contamination in fish is quite an old fact. Tuna is especially affected. Dolphins and toothed whales eat other fish, thereby concentrating the substances in themselves - that's why it's there.....sometimes measured at 200 times what is considered a "safe" level.I just realized something. If the dolphin meat is so much contaminated with mercury and pcb, shouldn't we worry more about the sources of that contamination? I mean, the Japanese hunt might stop not because of unhealthy meat but because the dolphins become extinct due to pollutants.
Should humanity pollute less? You betcha.... Unfortunately our track record is appalling in our treatment of the planet. That's why it's ridiculous IMO to single anyone out - the entire world has contributed to the build up and concentrations of toxic elements in the oceans. This isn't something that's just happened recently - it's been going on since the Industrial revolution, and to a smaller degree even before that.
No one is in a position to act in a self-righteous, holier than thou manner. They're ALL part of the problem - just like me.
That's why I find people like Paul Watson such utter hypocrites. Even if he manages to save a few whales (which is highly debatable), he's still putting large diesel engines to sea with all the extra pollution that adds........just like any of us divers flying to our diving destinations.....then going on dive boats etc. (like I will be doing next week)
I KNOW I live in a glass house.
How about everyone else?
