ABSTRACT
One of the challenges in understanding our global situation is getting good handle on each of the challenges as they are so diverse. For this reason, each of these Global Challenges is presented as an Executive Brief so the reader can quickly capture the issues and the opportunities. For readers familiar with an issue, a brief summary is presented at the beginning of each section. For readers who would like a greater understanding of particular challenges and potential solutions, the rest of the section provides a summary of the key aspects of each of these challenges.
