THE Earth is full. In fact our human society and economy is now so large we have passed the limits of our planet's capacity to support us and it is overflowing.
Our current model of economic growth is driving this system, the one we rely upon for our present and future prosperity, over the cliff.
This in itself presents a major problem. It becomes a much larger challenge when we consider that billions of people are living desperate lives in appalling poverty and need their personal economy to grow rapidly to alleviate their suffering. But there is no room left.
This means things are going to change. Not because we will choose change out of philosophical or political preference, but because if we don't transform our society and economy, we risk social and economic collapse and the descent into chaos. The science on this is now clear and accepted by any rational observer.
While an initial look at the public debate may suggest controversy, any serious examination of the peer-reviewed conclusions of leading science bodies shows the core direction we are heading in is now clear. Things do not look good.
