Only 3 % of Earth’s water is drinkable; agriculture consumes 66 % of it.
Valli states that merely 3 % of the planet’s water is accessible for drinking, with 2.7 % locked in polar ice. - Of the usable water, about two‑thirds is used for producing sugar, meat, rice, wheat, and eggs. - This massive allocation leaves insufficient water for other human needs and ecosystems.
Only a tiny fraction of Earth's water is drinkable; agriculture consumes the majority, especially for sugar, meat, and wheat production, while millet farming is far more water-efficient.
