The planet needs trees. If there is indeed that carbon dioxide out there in the atmosphere, the only species on the planet that can actually trap it for us in a natural process of photosynthesis are the trees.

What I am trying to say is that they need to learn to rely on themselves and to learn from other people, and when you learn something from other people, then you keep moving onward for yourself.

That's the way I do things when I want to celebrate, I always plant a tree.

Every one of us can make a contribution. And quite often we are looking for the big things and forget that, wherever we are, we can make a contribution. Sometimes I tell myself, I may only be planting a tree here, but just imagine what's happening if there are billions of people out there doing something. Just imagine the power of what we can do.

We’re constantly being bombarded by problems that we face and sometimes we can get completely overwhelmed. [But] we should always feel like a hummingbird. I may feel insignificant, but I don’t want to be like the other animals watching the planet go down the drain. I’ll be a hummingbird, I’ll do the best I can.

I don't really know why I care so much. I just have something inside me that tells me that there is a problem, and I have got to do something about it. I think that is what I would call the God in me.

We cannot tire or give up. We owe it to the present and future generations of all species to rise up and walk!
