Climate change ad battle heating up: Labor turned up the heat over federal government advertising as Prime Minister John Howard conceded a climate change campaign was on the way.

Recent years have seen the extinction of two sub-species of Indonesian tiger, the Caspian Tiger from western Central Asia, a sub-species of clouded leopard from Taiwan, and the Barbary lion from the wild in North Africa.
