The population of which animal does Australia try to control?

Platypus is the correct spelling!

It's the same in the UK when they introduced the grey squirrel back in the day. it has now practically eradicated the native red squirrel 😓

Andrew, cane toad is worse in that it is decimating native animal species withits toxicity.

Nearly as bad as the cane toad...

The Australian movie, Rabbit-proof Fence, is a must-see. It's about the Australian government's attempts to "civilize" the aborigines by forcibly taking the children from their families and "educating" them, like was done with Native Americans in the US and Canada. It's a truly heartbreaking part of history.

Platypus has no E.

I remembered seeing a movie about Australia where they mentioned rabbit fences, which were efforts to keep rabbits from overrunning certain areas.

I remember learning about this in college.
