Global warming and bushland

It was nice to see a reasonable crowd come to Cottesloe beach to urge the Government to do something about global warming.
I sometimes wonder what is going to happen to Shenton Bushland (and other bushlands as well) if we have severe global warming - how will the plants, insects, birds and reptiles adapt to the changing weather? It is quite disturbing really.
It was even more disturbing to hear government ministers lie to us about how concerned they were about global warming - while at the same time undermining any attempt to do something serious.
