How should we best use and protect Earth's freshwater ecosystems? This is the guiding question that students will research over the next two weeks in an in-depth case-study of the Great Lakes ecosystem. Yesterday, we looked at the 1972 Great Lakes Water Quality agreement between the United States and Canada that took measures to start the cleanup efforts of the polluted Lakes. The students are pointing toward a girl's shirt that says, "Happiness is Lake Erie!" How fitting after our study of the "Lorax!"
