Each human exhale carries approximately 200 milliliters of carbon dioxide. In one day, your breathing alone releases roughly 900 grams of CO₂ into the atmosphere.

This is not a burden. It is the cost of being alive — the quiet exchange between your body and the planet that has continued unbroken since your first cry.

The carbon in your breath was once part of a leaf, a grain of rice, a drop of water cycling through ancient stone. It will be again.
