The largest waterfalls on earth hold a precious secret: in the heart of one of the most endangered living spaces on earth – in the Atlantic Rain Forests – the stained jaguar searches for prey, the kittenish coati play in the highest tree tops and the bold apodiae glider plunges through thunderous water masses in order to provide food for their offspring. “Naturwunder Iguacu“ does not only show breath-taking air-views and fascinating animal stories but also wildlife guards who often risk their lives in their fight against the threatening demolition of this living space.
