It may come as a surprise to many people to learn that if it were not for the elephants, there would be few animals in the sandy, arid coastal regions of Africa. But this is, in fact, the case. Elephants are able to smell water where there is none on the surface, and in this area they dig holes to get the water that they need for themselves. When they have drunk up as much as they want, they leave the newly made holes, and immediately the other animals - which rely on the elephants for their water supply - come in and take their fill. Mervyn Cowie, Director of the Royal National Parks of Kenya, will tell viewers about this "Search for Water".
