an interesting stat on the northland australian wetland Kakadu. this is
probably instructive for comprehending other very fertile places of the
world which can tolerate stupendous quantities of wildlife. Considering the
pre-settlement population of aborigines is an estimated 300,000, imagine the
egg feast...

  Kakadu's most famous wildlife image is the wildest one of all - the
dinosaur that extinction forgot, the crocodile. But there are around 400
known types of birds, mammals and reptiles in the park and 399 of them are
not man-eaters. Birds are Kakadu's most visible inhabitants. The park is
known to contain more than one-third of all the bird species in Australia,
and its wetlands alone will sometimes support up to three million
waterbirds.
