Description
In the baked Namib desert, a pair of ostriches raise their family in the searing heat to keep them safe from predators - but time is ticking as the chicks begin to hatch. Outside of the egg, the new-borns won’t survive long in these temperatures, but not all of the clutch hatch at once. For the whole brood to survive, the parents need to time their departure perfectly, but tragically they are forced to leave behind an unhatched egg. As the family depart the new-born emerges and the lone chick wanders the vast Namib desert calling for its family. In the desert, life exists in a world with almost no water, and it drives one troop of desert baboons on a continual quest to find it - a young mother who is low in the pecking order must battle for her right to drink - her newborn’s life depends on it, without water her milk will run dry. As climatic change causes deserts around the world to expand, dust storms towering up to a mile high and travelling at speeds of up to 70mph overwhelm entire cities in an instant. Where rain falls regularly, it can transform a desert, turning it into one of earth’s most productive landscapes: grasslands. Grasslands support the biggest concentrations of large animals on the planet. This wealth of life, in turn attracts predators. Leopards are the most adaptable of big cats, and a handful of special individuals have learnt to hunt by hiding and leaping from tree tops - some higher than the roof of a two storey house. Their lives depend on them getting this unique game of hide and seek right, and when they do, their prey doesn’t see them coming. Grasslands are one of the most widespread habitats on earth and in the frozen north, herds of alien-like saiga antelope fight for their chance to win mating rights. 70% of rutting males die every year, in a battle that’s been taking place since the ice age. Closer to the equator, a grassland paradise can be found - the Cerrado in Brazil. This is the richest grassland on earth and home to the rare, fruit eating maned wolf. Little is known about this bizarre creature and for the first time ever, we glimpse inside the den of wild maned wolf. A mother raises her three puppies, but their future is uncertain. The Cerrado is a vitally important grassland - home to thousands of species of plants and animals found no-where else - and it is in danger of being lost forever. This grassland is being destroyed more than two times faster than the Amazon rainforest to clear land for farming. Reduced to 50% of its former size -some predict it could disappear completely in the next 30 years. But there’s hope, in central Africa - one of the world’s most spectacular wildlife gatherings is testament to what can happen if we help protect these precious ecosystems and allow nature to restore its own balance.
