Causing harm or destruction to the environment.
The ecocidal practices of some industries are leading to severe ecological damage.
Ecocidal is formed from "eco-" (from Greek "oikos", meaning house or environment) and "-cidal" (from Latin "caedere", meaning to kill). The word describes actions that result in the destruction of the environment or ecosystems.
Think of 'eco-' as relating to the environment or 'house' of nature, and '-cidal' meaning to 'kill'. This helps you remember that ecocidal refers to actions that kill or destroy the environment.
