00:00What if every ocean on Earth dried up completely?
00:04Three billion years of life gone in geological silence.
00:08Salt deserts the size of continents stretch across the ocean floor.
00:13The water cycle collapses.
00:15No evaporation.
00:16No clouds.
00:17No rain ever again.
00:20Temperatures swing 100 degrees between day and night like Mars.
00:24The air thins.
00:25Oceans produce half the oxygen we breathe.
00:29Within weeks the food chain unravels from the bottom up.
00:32Forests die.
00:34Animals die.
00:36Rivers run dry one by one.
00:38Humans survive perhaps a decade.
00:41Fighting over the last underground water.
00:43The oceans didn't just hold water.
00:45They held the conditions for everything alive.
00:48And without them, Earth becomes just another dead rock drifting through space.
00:53What do you think?
