What does environment mean?
An environment is the totality of surroundings — physical, social, or cultural — in which something exists or functions. The word is most familiar today in its ecological sense, where 'the environment' denotes the natural world, especially in discussions of pollution, conservation, and climate change. But its use is far broader: we speak of a supportive work environment, a stimulating learning environment, or even the software environment in which a program runs. The word carries a neutral connotation by itself, though it frequently appears in contexts of concern or advocacy when paired with words like 'protect', 'damage', or 'sustain'. Derived forms such as 'environmental', 'environmentalist', and 'environmentalism' have become central vocabulary in modern political and scientific discourse. Its flexibility — spanning ecology, psychology, business, and computing — makes it one of the most versatile and widely used abstract nouns in contemporary English.
The natural world, especially regarded as affected by human activity.
"New regulations aim to limit industrial damage to the environment."
Usually used with 'the' when referring to the natural world.
The surroundings or conditions in which a person, animal, or plant lives or operates.
"A quiet environment helps students concentrate."
(Computing) The hardware and software configuration within which a program runs.
"The application was tested in both development and production environments."
The plural is standard but less common than the singular, since the word often denotes a single collective setting; the plural appears when contrasting distinct settings.
"The species survives in a range of different environments."
The word 'environment' didn't always mean nature — it entered English meaning simply 'the act of surrounding,' and only in the 19th century did it come to describe the world around us.

Etymology of environment
'Environment' derives from the Old French verb 'environer', meaning 'to surround', which itself comes from 'environ' ('around'), formed from the prefix 'en-' plus 'voir' from Late Latin 'virare' ('to turn'), ultimately related to Latin 'viria' ('bracelet, ring'). It entered English in the early 17th century originally meaning 'the act of surrounding'. The modern sense of external surroundings developed in the 19th century, influenced by German usage in biology and geography, and the ecological sense became dominant during the 20th century.
