A study published by the Proceedings of the National Academy of Sciences on Monday shows that more than 10 percent of the land mammal species endemic to Australia have been wiped out since European settlement. The main culprit? Cats and foxes brought to the continent by those settlers.

But in sparsely populated Australia, much of the vast, desert interior remains virtually untouched by people. By global standards, it should be a paradisiacal safe-haven for animals.
