Scientists often consider past population trends to make predictions about future growth. Can we do the same with landscapes? Is there a way to examine how land has changed in the past twenty years? And can that help us predict how the land will look in twenty more? The answer to these questions is yes. Landscape trends are important because the quality of water in any lake is influenced by the condition of the land around it. Most important is green space - forested or vegetated land not broken by human development. The simple rule: more green space means more clean water.
