There's long been a fundamental problem with the green world — the  
myriad companies, activists, evangelists, politicians, clergy, thought  
leaders, and others who, each in their own way, have prodded us to  
address our planet's environmental ills. And it explains why, after  
four decades of the modern environmental movement, only a relative  
handful of companies and citizens have joined in, while many more have  
dragged their heels to slow, or even reverse, environmental progress.

The problem is this: No one has created a vision of what happens if we  
get things right.

That seems odd, when you think about it. We have a crystal clear  
picture of the consequences of getting things wrong (thank you very  
much, Al Gore). We know well the potential devastation of unmitigated  
environmental problems: the droughts, floods, hurricanes, tsunamis,  
resource wars, famine, and pestilence. We know about epidemics of  
childhood asthma in inner cities, toxic rivers in impoverished lands,  
and depleted fisheries that may never fully recover. We see for  
ourselves the rampant development in formerly verdant landscapes.  
There are vivid pictures of denuded forests, strip-mined mountains,  
and strip-malled farmland. We read about these things, hear Hollywood  
stars fret over them, and may even experience them firsthand.
