The food-chain that sustains a meat-eater could scarcely be shorter than it is here. [...] Algae that can uniquely tolerate these salty waters proliferate in the sunshine by the ton. Flamingos filter the algae from the water with their beaks, and vegetable is turned into flesh. And that flesh is food for eagles.
