My Prime Minister regards the economy as our highest priority and forgets that economics and ecology are derived from the same Greek word, oikos, meaning household or domain. Ecology is the study of home, while economics is its management. Ecologists try to define the conditions and principles that enable a species to survive and flourish. Yet in elevating the economy above those principles, we seem to think we are immune to the laws of nature. We have to put the ‘eco’ back into economics.

So we draw lines around our property, our counties, our cities, our states, our countries. And, boy, do we act as if those lines are important. I mean, we go to war. We will kill and die to protect those boundaries. Nature couldn't give two hoots about our national boundaries.

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.

Because countries often have differing political and economic systems, agreements are needed to protect those invested in trade.

If we want to move towards a low-polluting, sustainable society, we need to get consumers to think about their purchases.

With an estimated population of nine billion people by 2050, we cannot continue to consume resources at the same rate and maintain our quality of life.

Love is the force that makes us fully human.
