Japans radioactive workers have began dumping tons of water into the Pacific Ocean. They have started doing this in response the the high levels of radioactivity that continues to grow from the earthquake that ruptured the buildings that contained the nuclear energy. They have done this to reduce the radioavtive water in Japan. I dont think that this is very good for the ocean though. This could have a negative effect on the creatures that live there but specifics are still uncertain on the whole occassion.
