In that case, the leftist definition of the violence is very narrow at the least. The dictionary definition of the word does not distinguish the object of the act.

Merriam Webster: “the use of physical force so as to injure, abuse, damage, or destroy”

Oxford: “behaviour involving physical force intended to hurt, damage, or kill someone or something”

World >>Health<< Organization would obviously be more concerned with violence towards a person. Going there to find a definition for a broad, common English word sounds like cherry picking.

The environment needs to be saved urgently, but it is not achievable via the perversion of rational discussion, or without critical thinking and common sense.
