In this NASA Earth Observatory image made available by NASA on March 22, 2013, the southern tip of South America is seen at night in April of 2012. Off the coast, the lights of a huge fleet of shrimp boats can be seen, right along the maritime border between Argentina, the Falkland Islands and international waters. Scientists say this unmanaged fleet is threatening the South Atlantic marine ecosystem by depleting the squid, which are key to a food chain that provides sustenance for penguins, seals, birds and whales.
