"Invirementel" is not a recognized word in the English language. It's likely a misspelling of "environmental".

Environmental refers to:

* The natural world: This includes all living things (plants, animals, humans) and the non-living things that make up their surroundings (air, water, land, etc.).

* The impact of humans on the natural world: This includes the effects of our actions on the environment, both positive and negative.
