Reef ball burials: the new trend for becoming ‘coral’ when you die

Do underwater cremation memorials help people regenerate marine habitats in death or are they a greenwashing' gimmick?

Janet Hock is a former dentistry professor who lives in Indianapolis. She is also an avid scuba diver, with a long love of the ocean. We plod around on Earth, but there's this whole other world that teems with life - or used to," she says.

So when Hock, 77, updated her will in 2020, she added that she wanted to become part of a coral reef when she died. The unusual request means her cremated remains will be mixed into a perforated concrete dome, known as a reef ball. She will then become part of an artificial reef, having a second life on the seabed.
