Question

Meatless Mondays
Some people advocate for "Meatless Monday's" or eating no meat at all as a way to reduce global climate change. How does the consumption of meat relate to climate change?

Answer 1

1) Ruminant livestock (cattle, sheep, goats) produce methane (CH4) during digestion; methane is a powerful greenhouse gas (much higher warming potential than CO2 over decades).
2) Manure management and synthetic fertilizer for feed crops emit nitrous oxide (N2O), another potent, long‑lived greenhouse gas.
3) Land‑use change: forests and grasslands are cleared for pasture or to grow feed crops, releasing stored CO2 and reducing carbon sinks.
4) High energy and resource intensity: producing meat (especially beef) requires more cropland, water and fossil‑fuel inputs per unit of protein/calories than plant foods, so it generates more CO2 equivalents per serving.

So eating less meat (particularly beef and lamb) — e.g., Meatless Mondays — can lower greenhouse‑gas emissions and reduce pressure on land.
