Ashes to concrete: Sea burials help rebuild reefs

For those who want to help the environment in the afterlife, or forever be part of the memories at a sports stadium, a US company has a burial option to consider.

Eternal Reefs Inc of Decatur, Georgia, mixes cremated remains into concrete used to make so-called reef balls that it places at sites along the US East Coast, a service it markets as an environmentally friendly and less-expensive alternative to traditional burials.

Those interested in helping build a reef in a body of water don't have to wait until they die, said Eternal Reefs CEO George Frankel.
