00:05The ocean.
00:14The least explored of all.
00:22Yet by far the biggest part of our planet.
00:30Her creatures have challenges like never before.
00:46Survival gets tougher every year.
00:54Global warming means hiding from the sun.
00:58And a shortage of food means conflict with man.
01:09Time and tide drive their clocks.
01:17Their stories are told in three parts.
01:23Episode one visits the ocean's edge.
01:27This is a world where air and water mix.
01:40And being exposed must be avoided.
01:46Episode two meets shallow reefs.
01:55It's a deadly neighborhood.
02:04Coral still survives here.
02:07But for how much longer?
02:12Episode three, the deep, is least affected.
02:19Giants still cross entire oceans.
02:25But food is scarce.
02:28And behavior is changing.
02:34It is vast.
02:37It is delicate.
02:39It is dangerous.
02:44It is dangerous.
02:46It is under great threat.
02:51These are the survival stories of our epic oceans.
02:57The two, the world is bound.
03:03It is a new testament.
03:03The Who is Choe.
03:09The One, the space.
03:09The Moon.
