Let’s break this down step by step and estimate how many cows we’d need if everyone on Earth ate a carnivore diet with 80% beef, and then compare that to how many cows exist now.
---
Step 1: World Population
As of 2024, Earth has about 8 billion people.
---
Step 2: Diet Assumption – Carnivore Diet (80% Beef)
Let’s assume:
Each person eats 2,500 calories per day.
80% of those calories come from beef, so:
2,000 calories/day from beef per person.
That’s 730,000 beef calories per person per year.
---
Step 3: Calories per Cow
A typical cow yields about 500 pounds of edible beef.
1 pound of beef has roughly 1,000–1,200 calories.
Let’s average that to 1,100 calories/pound.
So:
500 lbs x 1,100 cal = 550,000 calories per cow.
---
Step 4: Cows Needed per Person per Year
Each person needs 730,000 beef calories/year.
One cow provides 550,000 calories.
So:
1.33 cows per person per year (730,000 ÷ 550,000).
---
Step 5: Total Cows Needed
8 billion people × 1.33 cows = ~10.6 billion cows needed per year.
That’s over 10 billion cows annually just to keep everyone fed.
---
Step 6: How Many Cows Are There Now?
Globally:
There are about 1.5 billion cattle (as of recent estimates).
Not all are beef cattle; some are dairy cows, oxen, or not slaughtered yearly.
---
Conclusion:
Current cattle population: ~1.5 billion.
Required cattle for global carnivore diet (80% beef): ~10.6 billion cows/year.
So we'd need 7 times more cows than currently exist—and every single one would need to be slaughtered annually, which is extremely unsustainable in terms of land, feed, water, emissions, and ethics.

Want me to calculate what kind of land or resources that would require too?
