The real conversation doesn't happen in individual consumption choices. It happens in which animals, which farms, which countries.
A grass-fed cow on regenerative land in New Zealand has a different carbon footprint than feedlot beef shipped globally. Chickens are nothing like cattle. Wild fish versus farmed. The system matters more than the category.
But the focus on individual meat reduction is convenient for the people selling other things. It shifts the problem from policy—which is political, expensive, and hard—to personal choice. Which is easy to market.
The actual environmental impact of agriculture is mostly about land use and fertilizer, not meat per se. And the people who've internalized the need to reduce meat are usually already the ones making consumption choices. You're not reaching the actual problem with that framing.
What changes things is regulation—how animals are raised, what's subsidized, how externalities get priced in. Individual guilt doesn't move that. It just makes people feel responsible for a system problem.
Can reducing meat help? Sure. But it's not the lever people think it is. It's psychological comfort disguised as action.
