Do you mean “new” water created by chemical reactions (combustion, metabolism, industrial chemistry), or do you mean whether the total amount of water on Earth increases each day? Brief answer up front:
- Net total water on Earth is effectively constant day to day — the hydrologic cycle recycles the same water. Practically no significant new H2O is being added to Earth’s total inventory on human timescales.
- If you mean water molecules made by chemical processes (anthropogenic + natural) each day, that does happen, but the amount is tiny compared with the planet’s water. Typical orders of magnitude: tens of millions of cubic meters per day from human activities, plus a few million cubic meters/day from human metabolism — negligible versus Earth’s ~1.386×10^18 m3 of water.
Details and quick estimates
- Earth’s total water ≈ 1.386 × 10^9 km3 = 1.386 × 10^18 m3.
- Combustion of hydrocarbons produces water. Example (approximate): world oil use ~100 million barrels/day (order‑of‑magnitude). At ~135 kg per barrel and ~1.4 kg H2O per kg fuel, oil burning alone might produce on the order of 1–3 × 10^7 m3 (10s of millions m3) of water per day. Adding coal and natural gas increases that, but still keeps the anthropogenic chemical‑production in roughly the 10^7–10^8 m3/day range.
- Human metabolic water: average person produces ~0.3–1.5 L/day internally. With ~8 billion people, that’s a few billion liters/day ≈ a few ×10^6 m3/day.
- Natural geochemical reactions and small cosmic inputs are orders of magnitude smaller or negligible on daily Earth scales.
Comparison: even if anthropogenic chemistry makes 10^8 m3/day, that is 10^8 / 1.386×10^18 ≈ 7×10^−11 of Earth’s total water — essentially zero.
If you want a more precise daily figure, tell me which sources to include (e.g., fossil‑fuel combustion only, include natural gas and coal, include industrial H2 production and fuel cells, include metabolic water), and I’ll run a more detailed calculation with current consumption data.
