Resumen:

Confluence : This book is a true confluence of art and science, politics and pragmatism, ideas and plans for action. It highlights the ways in which rivers connect us all to one another. While our society has made great progress in terms of local environmental improvement, such as cleaner water, we're still dodging the big issues, such as global warming. We have lost the vision of our planet gained in 1969 when astronauts sent back photographs taken from the moon.
