“This photograph, taken by an astronaut aboard the International Space Station, shows the straight line of the Corinth Canal as it crosses a narrow isthmus between mainland Greece (right) and the Peloponnese Peninsula. The canal cuts through the narrowest part of the isthmus of Corinth. The goal was to save ships from the dangerous 700-kilometer voyage around the ragged coastline of the peninsula.”

Questions to Ponder: What does the word Isthmus mean and how does this image help tell that story?  When did people start modifying Earth’s physical systems?  What factors do we need to consider when evaluating the impacts of human modifications to the environment?
