The medical literature tells us that the most effective ways to reduce the risk of heart disease, cancer, stroke, diabetes, Alzheimer's, and many more problems are through healthy diet and exercise. Our bodies have evolved to move, yet we now use the energy in oil instead of muscles to do our work.

Economics and a reliance on science and technology to solve our problems has led to an unsustainable situation where continued growth in consumption is required for governments and business to be considered successful. This is a form of insanity. Economics is at the heart of our destructive ways and our faith in it has blinded us

Conserving energy and thus saving money, reducing consumption of unnecessary products and packaging and shifting to a clean-energy economy would likely hurt the bottom line of polluting industries, but would undoubtedly have positive effects for most of us.

What about our children and grandchildren and their children and grandchildren? Do we not want them to live healthy and happy lives?

The human brain now holds the key to our future. We have to recall the image of the planet from outer space: a single entity in which air, water, and continents are interconnected. That is our home.

Water is our most precious resource, but we waste it, just as we waste other resources, including oil and gas.

Thanks to evolution, our bodies have powerful ways to ward off illness and infection and enable us to live long and healthy lives. Why, then, do health costs continue to climb at unsustainable and frightening rates?
