Here's why it's used to describe the surroundings we live in:
* It encompasses everything around us: Our environment includes all the living things (plants, animals, humans) and non-living things (air, water, soil, rocks) that surround us. It's everything that influences our lives and well-being.
* It's the context for our existence: We are not isolated individuals but exist within a complex system of interactions. Our environment provides us with resources, shapes our activities, and influences our health and development.
Think of it like this: Imagine you're standing in a room. The room itself, the furniture, the windows, the air you breathe, the sounds you hear – these are all part of your immediate environment. And then there's the broader environment beyond your room, the building, the street, the city, the planet – all interconnected.
So, the word "environment" perfectly captures the concept of the surroundings that envelop and influence us.
