A FOUNTAIN JOURNEY / FOLLOW THE ORANGE
Where does it go?
What we put into a system does not necessarily stay where we put it.
Follow the first connection ↓WATER → SOIL → FARM → FOOD → HUMAN
One journey. Several very different kinds of evidence.
Rain moves particles. Soil changes how nutrients are used. A crop travels through choices, prices and places before becoming a meal. Follow one material at a time; its next stop may surprise you.
- WATERRain can change what a river carries.
- SOILThe condition of the ground changes what an input can do.
- FARMA growing practice has a purpose and a route beyond the field.
- FOODThe crop becomes a meal through processing, transport and price.
- HUMANThe final question is whether nourishment is within reach.
The first connection is here. The full journey, its evidence and its onward Tracks continue with Passenger passage.

A label does not tell the whole story
The material, conditions of use and end-of-life route are separate questions.

What is the food question beneath the label?
An association raises a serious question without explaining every ingredient or choice.
