Malcolm Fraser, who was the Australian Prime Minister from 1975 - 1983, has an article that's well worth the read in The Age today, even if it's just to note the following statement:

Have we forgotten that we live in one world? Those who pollute the environment affect the entire world, not just their own countries. In economic matters our leaders speak of globalisation. But when it comes to people, we divide ourselves into islands, into separate groups, into races, into religions.
... When will we demand a return to decent, humane behaviour?

- We're all responsible for this government's inhumanity by Malcolm Fraser.
