Why is Australia the ideal environment for platypuses?
Australia is ideal for the platypus because there are few natural predators. Apart from pythons, most predators of the platypus are introduced species.
Why are the introduced species causing damage to Australian native animals?
In the first place, introduced species threaten the food supplies of native animals. Introduced species tend to breed more quickly than native species, so they eat more, often razing feeding grounds which would support native herbivores for months by eating vegetation right down to the roots. Secondly, many introduced species are predators, and native Australian animals have not developed effective defence adaptations against predators that are new to them. Introduced plant species tend to spread more quickly through native habitats, killing off native plant species which might provide the natural food of Australian animals.
