For proponents of ecosystem-based management,the good news is that another new book, Ecosystem-based Management for the Oceans, conveys the topic at its state-of-the-art level of development...both Marine Ecosystems and Global Change and Ecosystem-based Management for the Oceans are valuable troves that could profitably be mined, and any academic bookshelf would wear them well.

From the happy-go-lucky days of oil exploration and drilling, when a lot of easy sources were being found and easily managed, we're gotten ourselves into this sort of apocalyptic time.
