Going way back to the first job I ever had I’ve been aware of the role that water has played in the relationship humanity has with his environment. In that first job I had the fascinating pleasure of being exposed to aerial photography for (essentially) the first time.

When you see water in the landscape it becomes more obvious how great a role it plays. That’s what working with aerial photography did for me.
That first job was making wetlands maps. As the reports for each town came out, it was even more amazing and thought provoking to find out that there was a measurable percentage of wetland. One town we worked on was something like 29% wetland!
I was fascinated to learn why it is so important to conserve wetlands; I think that a lot of the value of wetlands have been brought to the forefront due to the devastating flooding following hurricane Katrina. Wetlands provide storm buffers and wildlife habitat, obviously, but also filter some contaminants from groundwater; all terrifically valuable tasks.
Since it is World Water Day, here’s a nice article I came across today I thought you might enjoy. It’s not new, but I like it anyway.
