"Water." "Falling on a city." "The sound of nature all around us." "Listen to what the rain has to say." "Follow it up to the clouds that sweep across the turning earth." "Far, far away." "To find a land where water shapes all life." "Where nature still holds sway." "Africa!" "Realms of fire and ice." "Water and wind." "Heat and dust." "Worlds within worlds." "Where we can be swept back into nature." "The rainforest." "The very heart of this vast continent." "The wettest place in Africa." "What lies hidden beneath this dense canopy of green?" "The mysterious forest." "With so much sun and rain, it grows relentlessly." "And all around the tangled forest is the noise of numberless creatures." "More animals live here than in any other realm." "But they're hard to find." "Hardly any light gets through." "And down here, on the forest floor, a leaderless army of blind ants is on the move." "Driver ants." "A swarm, five million strong." "You don't want to get in their way." "They eat everything in their path." "These tiny ants can overcome creatures thousands of times bigger than them." "It's war." "Animal devouring animal in the darkness." "While plants struggle desperately with each other to reach the light." "Life here can be a constant struggle." "But it's only a short walk to paradise." "In a glade in the forest, a family rests in the sun." "Gorillas." "Some of our closest relatives." "Just like us, they live in families." "Mothers and children, uncles and aunts." "The big silverback - he's in charge." "He keeps an eye on everyone." "For this family, the forest is really the Garden of Eden." "All the food they need is within easy reach." "They play, they talk, they quarrel, they learn and make friends for life." "It's an idyllic place to grow up." "This is their world." "They are really comfortable here." "And if anything threatens the peace the silverback is ready to protect his family." "Rain and sun made this rich forest." "But in the world beyond, another very different realm is being forged by a far more brutal clash of the elements." "The underworld." "The heart of a volcano." "A fiery furnace." "Where rocks melt before your eyes at temperatures of a thousand degrees." "You're seeing the earth stretch open." "When our planet was first formed, the whole world was like this." "Underground, the furnace still burns, making new land every day." "A world built from sulfur and salt belched from below." "Like an alien planet." "Acid pools and choking gases." "You can't even breathe the air." "Almost nothing can live here." "But sometimes, in the realm of the volcanoes, the fires breed life out of the poisoned water." "Lake Bogoria, where boiling springs from the underworld spill into a vast lake." "These waters are far saltier than the sea, yet they draw life from hundreds of miles away." "Flamingos." "'Flame' birds." "Occasionally, when the water conditions are just right, the lake blooms with masses of tiny algae." "A delicacy for the flamingos." "Their food contains a red pigment, so the more they sip, the pinker they glow as if they're blushing." "Now, the more they blush, the more desirable they become." "And when they're all looking beautiful... ..they start to dance." "# You" "# You and me" "# You # You" "# You and me. #" "Enflamed by the waters of the volcanic lake, they seek out partners in the crowd." "Who will choose who in this great gathering?" "Somewhere out there is the perfect match." "Out of the fires..." "Flamingos mate for life." "They are leaving the bubbling lake to find a place to nest." "Soon they'll be gone, the lake empty for another year." "But there are realms in Africa so dry, they seem permanently empty." "The Namib Desert." "It's been here for over 50 million years." "One of the oldest, hottest, driest places on earth." "A great sea of sand as restless as the ocean." "How can anything survive in this wasteland?" "But some do." "Millions of years have taught them the necessary tricks." "A desert viper, side-winding to get a grip on the loose sand." "Food's hard to find, so the viper hides and waits for it to come to him." "If you're going to hunt for a meal it helps if you have eyes in the back of your head." "Meet the Namaqua chameleon." "He sets his sights on an armoured ground cricket." "His eyes are bigger than his stomach." "Better try again for a lighter lunch." "Delicious." "In the middle of the day, the sand is so hot, most creatures can't stand it." "This little lizard's no bigger than your little finger and to stop his feet burning, he's got to dance." "The shovel-snouted lizard can handle the heat, but all that dancing works up an appetite." "He'd better be careful, though." "Not everything here is what it seems." "Tempting" "But is it safe?" "That was too close." "Time for a vanishing act." "With so little moisture in the dunes, there's only a sprinkling of life, and all of it's small." "But if there's rain, even a little, the water can change the whole character of a place." "East of Namib lies the realm of the scorched plains." "Water occasionally softens the earth, but now the land is bone dry." "It's a desperate time for elephants." "They have to drink more than any other animal on earth." "To find enough water at this time of year, the family must trek huge distances." "The smallest just have to keep up." "This is a family of females with their young." "One mother is in charge." "She has an incredible memory." "She can remember the few places where there might still be water." "They can't afford to rest until they find a drink." "They must push on through the night." "It's a dangerous time." "There are hunters about." "Leopards, hyenas, lions." "To keep their babies safe, the family needs to stick together." "Another family nearby have not been so careful." "This youngster has strayed too far." "Our family has survived." "The mothers were wise to keep their babies close." "Together their search continues." "Water at last." "The mother has led them to a special place where there's water underground." "To reach it, the elephants have dug wells with their feet and tusks." "Some of them are pretty deep, so the longer your trunk, the better." "A few mouthfuls can make all the difference." "Especially when you're small." "Thirsty bulls barging in for a drink." "Fortunately, the family's drunk enough and the mother knows somewhere nearby where they can all relax." "Too dirty to drink, but perfect for a mud bath." "A quick cool-off, a splash of the muddy sunscreen and it's time to move on again to find food and more fresh water." "Someone needs a bit of help." "Generations of elephants have gone on journeys like this and survived, passing on their knowledge and their courage." "They'll keep on travelling." "Always on the move, always thirsty until the rains arrive." "Fresh water is what brings the dry kingdoms of Africa to life." "These fingers of mist don't promise healing showers, but they beckon us towards another magical realm just beyond these sands." "The sea." "An eternal, restless empire at the boundaries of what we know." "Battering the shoreline of Africa from all points of the compass." "Barracuda." "Cruising in a shoal." "They seem to sense the path to take." "The traffic of the deep." "Ocean travellers, moving as one towards a wonderful creation of the sea." "The most vibrant of all Africa's realms." "A coral reef." "Reefs can only grow at the perfect temperature, at the perfect depth and with plenty of sunshine." "So they're rare." "But when it all comes together, you get this." "A crowded city under the sea." "A hawksbill turtle looking for food." "Like any human city, there are lots of different places to live." "And being so crowded, it pays to get along with the neighbours." "A quarter of all life in the sea lives on coral reefs." "It may be beautiful, but don't let the bright colours dazzle you." "Like most cities, the reef has its darker side." "When you leave the light behind, you never know quite what you'll find." "These sweeper fish like to shelter in caves." "But they seem pretty spooked." "A gang of lionfish on the prowl." "Beautiful, but deadly." "Their spines are highly poisonous." "And the stripes warn others not to mess with them." "Lionfish use their outstretched fins to corner their prey against the walls." "Sunbeams pierce the depths direct from the heavens." "Ride them to a kingdom in the sky among a sea of clouds to reach the top of the world." "A realm of ice and snow, right on the equator." "Mount Kenya, towering over three miles high." "Hidden among these snow-capped peaks is a secret world of strange plants."

"As the day heats up, everyone heads off to find food." "Families join up in their hundreds, searching for the best grass." "With so many monkeys together, things sometimes get a bit out of hand."

"Even if they do, they might drink elsewhere." "It's a long and winding river." "But if there's one thing crocodiles are good at it's being patient." "The wildebeest have to drink eventually." "Even the biggest crocs in Africa can't stop them all." "They have to keep moving to find a place where there's fresh grass." "That means chasing the rain."
