How so? Are you saying there is NO natural seepage of oil into the oceans?
If that is the case you would be very wrong, “Captain”.

Get me the GPS numbers of these oil “seeps” in the East GOM and I’ll go out and take a look and see what the bottom looks like there and if there are any oil slicks around. I imagine these seeps might resemble the springs I see on the bottom that seem to attract the Gag grouper in large numbers.
In fact...I’ve looked at the bottom of the Gulf for the most part 25 years and have never seen a seep or an unexplained oil sheen on top of the water anywhere.
The rest of the time I longlined the top water fish.
