Twenty-five million tons of debris from the tsunami in Japan last year is heading for the west coast of the U.S. and Canada. That's 25,000,000 tons or 50,000,000,000 pounds. "Most" of it is not radioactive because the wave action of the tsunami swept most of the debris out to sea before the Fukushima Daiichi nuclear reactors went all Kaboom! Fishing buoys already have washed up on the California coast the first of the flotsam to arrive. Predicting where and when more debris will arrive is difficult because even though 25 million tons is a lot, the pacific ocean is
lots and lots more.
