After the deadly Los Angeles area wildfires, there's growing concern about the nearby marine ecosystems. The ash and runoff from the fires settled over the Pacific Ocean for up to 100 miles. CBS News environmental correspondent David Schechter explains.

By coincidence, a research ship pulled up to Los Angeles as the deadly wildfires were burning thousands of homes, incinerating plastic, paint, asbestos and car batteries.

Nearly two months after the devastating wildfires in Los Angeles, some families whose homes survived the flames are uninhabitable due to toxic ash and smoke debris. Now, growing frustration as many homeowners with insurance through the California FAIR Plan fight for smoke damage coverage.

The Southern California wildfires that sparked eight weeks ago killed 29 people, burned 38,000 acres and destroyed thousands of homes, but researchers say the damage to the ocean is just beginning. David Schecter reports.
