I learned this over 50 years ago. Ruined a bathing suit in Florida when sea tar got on it, can’t get that stuff off. I have also read that seepage on the California coast was significantly reduced when off shore drilling started taking oil out of the seabed. Strange how these facts just don’t seem to get much publication, one could almost think there is an agenda involved.
Yep, if you fly over the Gulf on any sunny day and you’ll see round oil globules floating on the surface; lots of it.
