Ecocide is formed from "eco-" (from Greek "oikos", meaning house or environment) and "-cide" (from Latin "caedere", meaning to kill). The word refers to the act of killing or destroying the environment or ecosystem.
Think of 'eco-' as relating to the environment or 'house' of nature, and '-cide' as meaning to 'kill'. This helps you remember that ecocide means to kill the environment.
