Shifting Baselines: Putting the World's Oceans in Perspective.
The term shifting baselines describes the chronic, slowly degrading
changes in various ecosystems that are difficult to notice because they
occur subtly over time. While you might not have heard the term until
now, in recent years shifting baselines has become a buzzword of major
concern for many of the world's leading ecologists, environmental
biologists, environmental organizations, and everyone who is concerned
about the health of ecosystems around the world.
