What does ecocide mean?
Ecocide refers to the extensive destruction of the natural environment, whether caused deliberately or through reckless disregard for ecological consequences. Coined by analogy with 'genocide', it combines the Greek-derived prefix 'eco-' (relating to habitat or environment) with the Latin-derived suffix '-cide' (meaning killing), literally suggesting the 'killing' of the natural world. The term entered circulation around 1970 amid concern over wartime defoliation and industrial pollution, and it has since become a staple of environmental journalism and activist rhetoric. In recent years it has taken on a more technical dimension: a growing movement of lawyers, scientists, and politicians has campaigned for ecocide to be adopted as an international crime, comparable to genocide or crimes against humanity, so that individuals responsible for catastrophic environmental damage could be prosecuted. Because no such offence is yet firmly established in international law, the word still functions largely as a moral and political term, often used to condemn practices such as massive oil spills, deforestation, or toxic dumping. Its connotations are strongly negative and accusatory.
nounThe deliberate or reckless destruction of the natural environment, especially on a large scale; in international law contexts, a proposed crime covering widespread or long-term severe damage to ecosystems.
- Large-scale or deliberate destruction of the natural environment.
- In international law advocacy: a proposed criminal offence of widespread or long-term severe damage to the environment.
"Campaigners argued that dumping toxic waste into the river amounted to ecocide on an industrial scale."
"Environmental groups described the oil spill as an act of ecocide that would scar the coastline for decades."
"Several small island nations have formally backed the campaign to recognise ecocide as a crime under international law."
Rarely pluralised; the uncountable form is standard. A plural may appear when contrasting distinct instances or proposed legal definitions.
"Historians have catalogued the ecocides committed during the twentieth century's industrial expansion."
The word was coined in 1970 at a conference on war and environmental damage — and half a century later, lawyers are still pushing to make ecocide an official international crime alongside genocide.

Etymology of ecocide
Ecocide was coined in English around 1970, formed by analogy with 'genocide' (itself coined in the 1940s). It joins the combining form 'eco-', from Greek 'oikos' meaning house or habitat, with '-cide', from Latin 'caedere' meaning to cut down or kill, as found in homicide, suicide, and pesticide. The word gained early prominence in discussions of American defoliation campaigns in Vietnam and has since been extended from warfare to industrial and commercial environmental destruction. Its cognates are the many other '-cide' formations rather than direct borrowings into other languages, though the term itself has been adopted widely across European languages.
How ecocide is actually used
The word is relatively formal and often carries strong moral or political connotations, appearing frequently in environmental activism, journalism, and legal debate. It is commonly used hyperbolically for severe but localised environmental damage. Its status as a recognised international crime remains a matter of proposal rather than settled law, so careful writers often note this context.
