Greenpeace Ships Don't Run on Determination & Justice?!

Greenpeace environmentalists have seese and desisted (yeah, I wrote desisted) their chase on Japenese Whalers. The militants for ocean justice were forced to return to shore because they were running out of fuel. Damn those Japanese whalers and their ginormous fuel tanks.
"We need to make every effort to keep the pressure on the Japanese whaling fleet, to keep them on the move and to keep them from killing whales. Given the fuel, we can keep up the pressure," Sea Shepherd's founder, Paul Watson, said in a statement.
No word yet on when, or if, they'll return the persuit.
