Large piles of household debris destroyed by the tsunami are seen at a sorting site on March 10, 2012 in Rikuzentakata, Japan.
All up and down California, an estimated 70,000 people will join together this Saturday for the state's annual coastal cleanup, picking up trash on beaches, near creeks and in rivers.
But contrary to what was expected, 2.5 years after the deadly earthquake and tsunami in Japan, very little of that debris has ended up on our coasts.
San Jose Mercury News environmental reporter Paul Rogers asks, 'where has it gone?'
Volunteers are still needed for the annual coastal cleanup on Sept. 21, which runs from 9 a.m. to noon. To volunteer, call 800-COAST-4U or visit the California Coastal Commission website.
