Human Impact to the World’s Oceans
For a really “big picture” view of how we are impacting the our planet’s oceans, download the KML file from UC Santa Barbara’s National Center for Ecological Analysis and Synthesis: www.nceas.ucsb.edu/GlobalMarine
Load it into Google Earth and circle the planet. The data is the result of a study that concludes “over 40% of the world’s oceans are heavily affected by human activities and few if any areas remain untouched”. Our ecological footprint is not only large, it’s also very wet.
