The ocean floor is collapsing. Maybe all the oil will eventually fill one third of the oceans.
"The second angel poured his bowl into the sea, and it became like the blood of a dead man, and every living thing died that was in the sea" (Rev, 16:3).
Rev. 8:11 says the cause is a celestial body? If a "star" is "wormwood", how can it make the "waters" 'wormwood meaning bitter"?
If there is any more volcanic ash that causes a "volcanic winter", will one third of the sun be eventually blocked out and daytime will be shorter? (verse 12).
You can't insure the sea floor. If it collapses, the oil will fill the ocean until with reddish-brown sludge that the earth will bleed until the gulf oil deposit is empty.
