In the aftermath of the 1992 meeting, too many nations, including the United States in particular, failed to reverse the downward trend in planetary ecosystem health. Today, with a global population of 7 billion consuming resources beyond the ability of the earth to replenish itself, we'd better hope there's a better attempt at the transition to a sustainable economy after this meeting.</p>
