Trees are the earth's endless effort to speak to the listening heaven.

We have to get to the point where we all come together, and we realize that we're all on the same Earth, and there's one way we can fix it.

The earth we share is not just a rock tossed through space, but a living, nurturing being. She cares for us. She deserves our care in return.

The earthquake, however, must be to every one a most impressive event: the earth, considered from our earliest childhood as the type of solidity, has oscillated like a thin crust beneath our feet; and in seeing the laboured works of man in a moment overthrown, we feel the insignificance of his boasted power.

The tour can keep on going with another headliner. It's about sustainability and renewability in the future, loving Earth for what it is. We want to do the right thing. That's kind of the idea.

We need to grow food, and we need to grow fuel. Imagine if, instead of dust rising into the sky, the carbon started returning to the Earth.
