A new map by a group of scientistsat the National Center for Ecological Analysis and Synthesis have created a map that shows man's impact on the oceans.
The map shows only four percent of the world's are left mostly untouched by humans. These are found hugging the coast of Antartica, very remote northern Russia, and very remote regions of the northern islands claimed by Canada.
The places impacted the most and worst are the North Sea region (lots of British and Norwegian oil drilling), the East China Sea (China's economic output is literally pouring into the sea), and the Singapore straits (one of the most heavily trafficked bodies of water).
Man's impact on the oceans is vast ranging from horrible dead zones to positive things like artificial reefs. So like terra firma, the ocean's are now as much a cultural landscape as they are a natural landscape.
