I will be Green until the day I die, if not for a long time after.

There's a presumption that somehow you calculate beforehand whether something is going to be good politically or not. I simply don't.

In securing the future of the planet, we secure happiness for ourselves. One of the aims of the Greens is to turn around the tide of pessimism amongst the young people of the world.

I am aware that one should always make room for renewal in politics. A democracy is the healthier for the turnover of the depth of talent there is in its community.

The reality is that if we in this rich, lucky quarter of the planet cannot make a stand for the 30 million other species we share this planet with, let alone our own species, then who can?

With a small fraction of the hundreds of billions of dollars spent on the Iraq war, the US and Australia could ensure every starving, sunken-eyed child on the planet could be well fed, have clean water and sanitation and a local school to go to.

The future will either be green or not at all.
