What gave her [Diane Wilson] the courage? If you look at someone like Diane, it's easy to say, well I could never be like that. But we don't know. We do know that it's possible for a woman, who didn't grow up as a world changer, to find it in herself to take a stand.

What an extraordinary time to be alive. We're the first people on our planet to have real choice: we can continue killing each other, wiping out other species, spoiling our nest. Yet on every continent a revolution in human dignity is emerging. It is re-knitting community and our ties to the earth. So we do have a choice. We can choose death; or we can choose life.

No society has fulfilled its democratic promise if people go hungry... If some go without food they have surely been deprived of all power. The existence of hunger belies the existence of democracy.
