What if everyone ate a bit less meat?
Skipping one typical meat meal avoids roughly 3 kg of CO₂e and about 1,100 litres of freshwater — modest alone, but it multiplies. A family, a classroom, or an office each skipping a few meat meals a week adds up fast. Slide the numbers and see.
In one year, that group would avoid roughly:

of CO₂e — —
—
of freshwater — —
—
meat portions left off plates
How it's calculated
Each skipped meal is a 150 g meat portion replaced by a plant-based one. Per-kilogram footprints come from Poore & Nemecek (2018, Science) — beef ≈ 60 kg CO₂e/kg, chicken ≈ 6 — and farm-to-plate freshwater estimates (beef ≈ 15,000 L/kg). The "typical mix" option blends beef, pork, and chicken into ≈ 3 kg CO₂e and ≈ 1,100 L per meal, minus a small allowance for the plant meal that replaces it. Comparisons: one Paris–New York round-trip flight ≈ 1 t CO₂e per passenger, one Olympic pool ≈ 2.5 million litres. All figures are global averages — honest orders of magnitude, not carbon accounting.
