Our nature is intelligent. In fact, everything is intelligent. Intelligence for me is information. Information is intelligence. And then there is information driven by energetics. And the energetics is operated by the matter, which has manifested here. This is where you and I come in. The human body is matter. Plant material, and this tea I am drinking, is matter.

Clone ourselves through teaching others.

What's sad is that nobody knows the constitution of the ecosystem that has just been destroyed. Is it an important future food? Is it an important medicine? What can it do for future generations - or present generations?

We are clearcutting virgin forests around the world, and 95 percent of species in the clearcut zone have never been studied. So we clearcut a part of the virgin forest and now part of our ecosystem has been wiped out. Some of it may grow back, and some of it won't.

One of the best antidotes for depression is to look around and see what you can do to help out - to make a difference - for now and the future. Now is the future, for what I do right now is the future. For what I am doing right now is already affecting tomorrow.

Species are being wiped out every day. Do we want to live with this or don't we? That is really our choice. And I think that human beings, by nature, want to preserve themselves. But right now, we're so preoccupied by other stuff, and we're not addressing the issues, which are our priorities.

By nature, we are a plant-based intelligence - not just our exhale, which plants inhale, but they are my food chain. They are my medicine. I cannot live without plants. They are part of my life support. And this is why plant species need to be preserved.
