Sumbiocide is the deliberate killing of symbiotically unified communities of life at all scales. Sumbiocide is inflicted by humans on the living parts of the symbioment (environment). It is a sub-set of ecocide or the deliberate destruction of the living and non-living elements of ecosystems. Sumbiocide is the systematic destruction of the life present in symbiotically unified communities.

For example: “The destruction of the symbiotically created and unified coral reefs of the world by Anthropogenic climate change is the human act of sumbiocide”.
(sumbio: Greek from ‘sumbios’, meaning to live together and; cide: Latin from cida, meaning killer).
