It is known that the concept of ecology was introduced into science in 1869 by the German biologist Ernest Haeckel. The scientist used the word "ecology" as a section of zoology (biology) expressing the interaction of all living things with the external environment. The word ecology is a Greek word meaning "oikos" - home, place of residence, "logos" - science, teaching. It should be noted that although ideas related to ecology were mentioned in the works of such scientists as Hippocrates and Aristotle, it emerged as a science much later.
