In 1992, 1600 scientists including 102 Nobel Laureates put their signature to a document titled “Warning to Humanity” which stated: “No more than one or two decades remain before the chance to avert the threats we now confront will be lost and the new prospects for humanity immeasurably diminished. A new ethic is required – a new attitude towards discharging our responsibility for caring for ourselves and for the Earth. This ethic must motivate a great movement convincing reluctant leaders and reluctant governments and reluctant peoples themselves to affect the needed changes”.

Two decades later not much has changed in the way of attitude or a new ethic from a global viewpoint. But much is changing from an ecological perspective with scientists fearing that many tipping points have already been reached. I wonder what it will take for reluctant leaders, governments and people to finally understand the big picture … and then to make the monumental changes required to reverse this darkening picture? Never before has there been this degree of responsibility for humankind. I can only hope that we are up to the challenge!
