Instead of cremations or burials, environmentally conscious people are looking for more sustainable ways to handle their remains when their time comes, and Hawaii Memorial Reefs has just such a proposition. The company allows people to use their remains to actively encourage the growth of sea life by mixing cremated ashes into "Reef Balls."
Reef Balls are rough, holey concrete structures that sit on the sea bed. These artificial casts are specially designed to encourage the growth of coral reefs. Coral needs to find a solid place in order to flourish, and the sea flora is agnostic to whether that base is natural or artificial. As such, Hawaii Memorial Reefs' Reef Balls are the perfect way to make one's final act environmentally friendly.
