2016 óta folyamatosan fejlődünk

Az ökológia napja az ökológia 150. évfordulójának 2016-os ünneplésén fogant meg az Európai Parlament kerekasztal beszelgetésén, Brüsszelben.

A dátum, szeptember 14, az a nap, amikor Ernst Haeckel kiadta az „Ökologie und Chorologie” cikket (Haeckel, 1866, II: 286–289, újranyomva: Acot 1998: II, 703-706), amiben meghatározta, mi is az ökológia.

By ecology, we mean the whole science of the relations of the organism to the environment including, in the broad sense, all the “conditions of existence”. These are partly organic, partly inorganic in nature; both (...) are of the greatest significance for the form of organisms, for they force them to become adapted. Among the inorganic conditions, (...) we consider the physical and chemical properties of its habitat, the climate (light, warmth, atmospheric conditions of humidity and electricity), the inorganic nutrients, nature of the water and of the soil, etc. As organic conditions we consider the entire relations of the organism to all other organisms with which it comes into contact, and of which most contribute either to its advantage or its harm. Each organism has among the other organisms its friends and its enemies, those which favor its existence and those which harm it. The organisms which serve as organic foodstuff for others or which live upon them as parasites also belong in this category of organic conditions of existence. (...) In a word, ecology is the study of all those complex interrelations referred to by Darwin as the conditions of the struggle for existence


SPECO, the Portuguese Ecological Society, has been coordinating the initiative in close association with European Ecological Federation (EEF) since 2017. In Portugal, the Ecology Day has been endorsed by High Patronage of the National Commission of UNESCO.

In 2019, two years later, Ecology Day reached an international scale, thanks to its celebration in the United States of America, Russia, India and Mozambique. The official setting of the date depends on the scale of the initiative, which shows an upward trend.
