"He is entirely dependent on his mother." "It may be spring, but the temperature can still drop to minus 20 degrees and winds of 70 miles an hour roar across the ice." "All his mother can do is try to shelter him with her own body." "Trust that she can keep her infant alive." "So why has she chosen here, of all places, to have her pup?" "It's because here, they're safe from their enemies." "ln the middle of this vast frozen sea, no predator can reach her or her baby." "but there's no food here." "So the mother keeps this ice hole open, the only route to her hunting ground." "And it must become his hunting ground, too." "She has to persuade him into the water." "He's not keen." "And who can blame him?" "but he soon discovers this is where he was born to be." "Now, life's adventure can begin."

"Outside the pool... everyone else." "The youngest princess can luxuriate because she has an extended family determined to give her the best in life." "Not everyone has the advantage of such a supportive family." "Some have to depend on a dedicated single mother." "And here she is." "A strawberry poison arrow frog no bigger than your fingernail." "She's laid her eggs on the forest floor." "For most frog mothers that would be the job done." "but her maternal instinct is so strong she guards them until they've hatched, and then she moves her tadpoles out of danger." "She hitches a tadpole on her back, then sets off." "Surprisingly, she starts to climb." "And this is what she's looking for:" "a special plant way up in the branches of a tree, ¤0 feet above the ground." "There's water trapped in its leaves that makes it a perfect nursery pool." "She has to leave him because she still has 4 more tadpoles waiting on the forest floor, and each must be carried up to its own private nursery." "There's nothing to eat in these pools, so she feeds each tadpole with one of her own unfertilized eggs." "A single egg won't sustain a hungry tadpole for long, so every few days, she has to climb back up to each youngster... and do it all over again." "One day, this fine young frog emerges from his pool, and leaves his devoted mother behind." "(growling)" "(adult gorilla snorting)" "There are fathers who do their bit, too."

"Every day." "365 days a year." "(upbeat music)" "So why are they doing it?" "The answer lies deep underground." "(cringing)" "They chop it up and feed it to a fungus that can eat grass." "And then they eat the fungus." "The anthill is a massive underground farm." "It's a perfect arrangement, except that the fungus produces so much carbon dioxide it poisons the air down here." "The ants have sorted that problem, too." "They've built specially designed ventilation shafts to keep their air clean." "They're farmers, architects and engineers." "Each individual ant has a brain the size of a pinhead." "but somehow, together, they have invented a solution to feeding themselves that we would be proud to match."
