Giraffes: Africa’s Gentle Giants

 

What does it take to relocate a herd of wild giraffes in Africa? One man, his family, and a band of enthusiastic helpers are about to find out. Their journey will take them across the wild heart of Uganda, crossing the mighty Nile River. The importance of this operation cannot be underestimated, because these are Rothschild’s giraffes, the world’s rarest. Any mistake could be costly, not only for the giraffes being moved but also for an entire species.

Sinkholes: Buried Alive

 

In Tampa, Florida, in February 2013, a giant hole opened up under the bedroom floor of Jeffrey Bush, swallowing the 36-year-old as he slept. His body was never found. Bush was a victim of a sinkhole – a growing worldwide hazard that lurks wherever limestone and other water-soluble rocks underpin the soil. When carbon dioxide in the air dissolves in rainwater, it forms a weak acid that attacks the soft rocks, riddling them with holes. Sinkholes can occur gradually when the surface subsides into bowl-shaped depressions or suddenly, when the ground gives way – often catastrophically.

Super Hummingbirds

 

Speed is their middle name. Their lives are moving faster than the eye can see. They possess natural born super powers that enable them to fly backwards, upside-down and float in mid-air. And for the first time, we see them mate, lay eggs, fight and raise families in intimate detail. They are great athletes, tender mothers, brave in combat and up for any challenge. They are Super Hummingbirds, the smallest and most brilliant birds on earth.

Killer Landslides

 

In less than two minutes in March of this year, a one-square-mile field of debris slammed into the Washington state community of Oso, killing 41 and destroying nearly 50 homes. Drawing on analyses of other recent landslides around the world, geologists are investigating what triggered the deadliest U.S. landslide in decades and whether climate change is increasing the risk of similar disasters around the globe.
