... laws governing pollution tend to move pollutants from one medium to another. So, for example, we scrub SO2 from power plants only to dispose toxic sludge on land. We "clean" water only to disperse toxic-laced solids on farmland or landfills. Pollution control becomes a kind of giant shell game by which we move pollutants between air, water, groundwater, and land.

Journey of the Universe is eloquent, accessible, and powerful, and conveys a sense of wonder ranging from the cosmos to the microcosm--in itself a considerable achievement. This is one of the most compelling and inspiring works I've read in a long time.

For three decades and longer we have been developing the ideas, science, and technological wherewithal to build a sustainable society. The public knows of these things only in fragments, but not as a coherent and practical agenda indeed the only practical course available. That is our fault and we should start now to put a positive agenda before the public that includes the human and economic advantages of better technology, integrated planning, coherent purposes, and foresight.

It is much easier to make intellectual messes than it is to clarify complicated issues, especially when real solutions would challenge the status quo and require much careful thought across many fields of knowledge. Problems of climatic change, biotic impoverishment, population growth, and the choices to be made by various technologies and the transition to a sustainable and decent society with an economy that works over the long-term are difficult, complex, and intertwined problems with many possible answers.

In an ecological perspective, in other words, there are few accidents or anomalies, only outcomes based on system structure and dynamics. Climate change and glittering malls, Calcuttan poverty and sybaritic wealth, biotic impoverishment and economic growth, militarism and terrorism, global domination and utter vulnerability are not different things but manifestations of a single system.

Unrestrained automobility, hedonism, individualism, and conspicuous consumption cannot be sustained because they take more than they give back. A spiritually impoverished world cannot be sustained because meaninglessness, anomie, and despair will corrode the desire to be sustained and the belief that humanity is worth sustaining. But these are the very things that distinguish the modern age from its predecessors, Genuine sustainability, in other words, will come not from superficial changes but from a deeper process akin to humankind growing up to a fuller stature.
