Seeing the whales off James Price Point, mothers, babies, bull whales, seeing the count, going up into the thousands of these whales, the assurance that they will be ok with a mega port, mega ships and a huge factory ashore, is now clearly proven wrong.

So far as we know, Earth is the only planet which supports life, and it is the only planet on which we can survive. Our bodies and our minds are fashioned by it. Our hearts resonate with it. There will be little joy for the human spirit if we destroy the natural fabric of Earth with nothing left to do but go shopping. When we imagine the world a century from now, when we look our great grandchildren in the eye and see them smiling back at us because they know we cared for them, we smile too!

We must have an expansionary vision, one that captures the imagination and diversity of the whole community, one which benefits a nation which has moved beyond the basics of literacy and numeracy and which wants to develop a learning culture.

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.

I have seen such an immense change from the total repression and criminality of homosexuality in my lifetime. It does make me much more buoyant and optimistic about the future. If that change can occur in that time there's hope for many other changes.

I am not a conventionally religious man, but in the wilderness I have come closest to finding myself and knowing the universe and accepting God - by which I mean accepting all that I don't know.

The Greens will continue to champion a fairer society rather than simply the economy and to champion the parliament rather than simply the stock exchange .

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.

Globally the Greens have arisen like a spontaneous combustion, a reaction to the narrow-minded state-backed exploitation of resources and wealth for a few at the expense of the many.

There are better alternatives, ... Australia should be exporting its solar technology, not its uranium.

Every time I get a bit worried about having made some second rate choices in life I go back and read about the Suffragettes or William Wilberforce, people who were 'wrong' in their own time, and think, 'Ah well.

The future will either be green or not at all.

We are all born bonded to nature; that's why we put depictions of flowers and forests, rather than bulldozers or log piles, on our walls.

Exxon, Coca-Cola, BHP Billiton and News Corporation have much more say in organising the global agenda than the planet's 5 billion mature-age voters without a ballot box.

Behind every successful man there's a lot of unsuccessful years.

The pursuit of eternity is no longer the prerogative of the gods - it is the business of us all, here and now.

We calculate the amount spent [by Brethren and other anti- Green groups] was between $500,000 and $1 million - that's a huge amount for a state election campaign in Tasmania.

The government's living in its own cloud cuckoo land and it's a cloud of greenhouse gases.

We people of the Earth exist because our potential was there in the Big Bang, 13.7 billion years ago, as the universe exploded into being.

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

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 overarching factor to me is if we can't be kind to each other, we won't be kind to the planet.

Australia must prioritise education spending. It is not a question of whether or not we have the money, it is a question of how we choose to spend it.

Real life security and contentment come not from putting a gun in the cupboard, but from taking a role in the world's future.

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?
