Everything we put in and on our bodies must be nutritious and safe.

The tea is pure chemistry, and so is everything else. But chemistry can be highly active with nutrients, it could be not very active and empty of nutrients or it could be a toxic, polluted substance. That's what interests me as an environmentalist, because I think we should only produce the purest, finest things. Then there would be no toxic side effects. There would be no wastes, because everything would be used responsibly.

Ask ourselves: How can we serve, nurture and sustain the planet and its people in our business ventures?

We are taught to reinvent ourselves all the time. And nature is teaching us. What is necessary for us to do to create sustainability? There's a shift that has to take hold in our thinking, and it's hard to know when it's going to click for the larger percentage of us.

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.
