Growing plants for protein creates way less pollution and uses far less water than raising cows for meat.
Evidence from Studies
Supporting (1)
Community contributions welcome
This study says that proteins from plants like beans and peas cause way less pollution and use much less water than beef, which matches exactly what the claim says.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether plant protein systems consistently outperform red meat in GHG emissions and water use across global contexts.
A systematic review and meta-analysis of 50+ peer-reviewed life cycle assessments comparing GHG emissions (kg CO2-eq/kg protein) and water use (m³/kg protein) for soy, pea, lentil, and red meat (beef, lamb) across regions, using standardized LCA methodologies (ISO 14040).
Whether population-level shifts toward plant protein consumption correlate with reduced agricultural emissions and water use over time.
A 15-year ecological cohort study tracking national dietary protein consumption patterns and national agricultural emissions/water use data in 30 countries with varying plant protein adoption.
Whether regions with higher plant protein consumption have lower per capita agricultural emissions.
A cross-sectional analysis of 100 regions comparing per capita plant protein intake (g/day) with regional agricultural GHG emissions and water withdrawal per kg protein.
Whether farms producing plant protein have lower emissions than those producing beef.
A case-control study comparing 50 beef farms and 50 plant protein farms (soy, pea) matched for size and location, measuring on-farm emissions and water use via direct monitoring.
Expert consensus on the environmental superiority of plant proteins over red meat.
