methane vents on the sea floor!! How ever did all of that hairspray and Freon get under the seabed to poison the planet?? How did mankind put all that terrible methane there? Are there COWS under the seabed? NATURE?? Living planet?? Impossible! WE must be to blame- especially evil Americans!! Right? /sarcasm. As if the stoners on the west coast would notice a little methane.
