What would happen if everyone stopped eating meat tomorrow? - Carolyn Beans

Summary

The video imagines a sudden worldwide end to meat consumption: meat disappears, people lose the desire to eat it, and animals raised for food vanish. It traces the possible effects from the immediate aftermath to changes over centuries.

Immediate environmental change

Food-related greenhouse-gas emissions would fall by about 63%, according to the video.

Food and nutrition pressures

People would need to replace nutrients and protein previously supplied by meat and seafood. Diets based on fruits, vegetables, and legumes can provide the nutrients needed for a healthy life, but existing supplies would initially be insufficient, pushing up prices.

Uneven social and economic effects

Communities that depend on meat or fishing for food, income, or cultural and religious practices could face serious disruption. The video gives Mongolia and salmon-eating tribes in the Pacific Northwest as examples. Many workers and households reliant on livestock or fishing would also lose their livelihoods.

Changes in agriculture and costs

Some meat producers might shift to growing crops. As crop production expands and land used for animal feed becomes available, food prices could eventually fall. Vegetarian diets could become less expensive than meat-based ones in most countries. The video says these diets would generally require less land and water.

Potential health benefits

The shift could prevent some deaths by reducing conditions associated with red-meat consumption, such as heart disease and cancer. It could also reduce exposure to pathogens linked to hunted wildlife and farmed animals, as well as antibiotic-resistant bacteria associated with antibiotic use in cattle.

Potential ecological recovery

With less agricultural pressure, habitat loss and pesticide use could decline. The video describes possible benefits for forests and wildlife, pollinators, and ocean species affected by overfishing. More pollinators and natural habitat could also benefit some crops.

Possible long-term biological change

Over thousands of years, human populations might evolve traits that help them process plant fats more efficiently, or lose some adaptations that help extract iron from meat.

Practical takeaway

The scenario is a thought experiment, not a prediction. Since meat consumption is still rising globally, the video argues that reducing beef, cheese, and milk consumption could deliver some benefits without requiring everyone to stop eating meat. It also cautions that a vegetarian diet high in dairy may produce more greenhouse-gas emissions than a diet with modest amounts of chicken.
