How Nature Works

In this episode, we travel to the savannahs of Kenya; the grasslands of Australia; and the Cerrado of Brazil to witness how one of our most important ecosystems works – grasslands. In Kenya we witness the surprisingly important role that rhinos play in making the grasslands fit for antelope. In the Brazilian Cerrado, we reveal how maned wolves get by on a low nitrogen diet, with the help of an odd dietary supplement – a fruit.
