Take one breath and try to trace it. The easy story is the tree outside your window. The true story is stranger. About half of the oxygen on this planet is made in the ocean, most of it by plankton. Green specks, too small to see, drifting in water you may never visit.
So the breath you just took is partly the sea's work. You are plugged into an ocean you have possibly never seen, and the connection has never failed once in your whole life.
That is exactly why you cannot feel it. The brain files whatever never changes as background. A fridge hums all day and you hear nothing until the motor cuts out. Nature is the hum that has not cut out yet.
Rain arrives. Soil turns seeds into food. Bees work the orchards. Plankton makes the air. None of it sends an invoice. None of it sends a notification. Systems that fail get your attention. Systems that work disappear.
You think of yourself as a solid object moving through a world of other objects. Look closer and you are more like the shape a river makes. The water keeps changing. The shape stays.
Breakfast becomes blood. The glass of water becomes you by evening. The breath going out carries carbon that was part of your body a moment ago. Material flows in from the world, wears your face for a while, and flows back out. The border between you and nature is a habit of speech.
Modern life dresses all of this up. Milk is a carton, not a mother. Chicken is a shape in plastic, not a bird. An apple is a barcode, and the spring of bee work inside it is invisible at the register.
The shelf is not lying to you. It is just the costume. Under every product in the store is a field, a season, an animal, a water table. The system is still there. The packaging is what you see instead.
Nobody decided to hide nature from you. There was no meeting. Pipes, roofs, shelves and screens each solved a real problem, and each one placed one more layer between you and the machinery keeping you alive.
The forgetting was never the plan. It came free with the convenience. Stack up enough layers and a person can live a whole year without once remembering what their body runs on.
Listen to the phrase we use. Getting out into nature. As if it were a place, somewhere past the parking lot, open on weekends.
You cannot get out into a thing you never left. You are the sea's air and last year's sunlight, walking around in shoes. The forest is not a destination. It is a relative's house. There is no outside.
