Thank you for sharing a bit of that conversation with your friend. The more I think about it, the more I realize how great a simple egg is for this example.

The current U.S. egg consumption is 250 per capita per year. With a U.S. population of 310 million people, that’s 77,500,000,000 eggs per year or 212,328,767 eggs per day.

If all 7 billion people on the planet consumed the same number of eggs as the United States, that would be 4,794,383,558 (4.7 billion) eggs per day, or 1,749,949,998,983 (1.7 trillion) eggs per year.

Is that sustainable? Does that even make any sense on a global scale? No. There are simply better ways of getting the same nutrients for such a large number of people.

To me, that makes it plainly obvious that consuming eggs makes no sense, farm raised or not. It’s setting a bad example and maintaining a status quo that impedes human progress. The same is true for consuming meat and fish.

(I’m not blind to the reality that in some parts of the world people don’t have a choice; some people live in areas where vegetables and fruits simply cannot grow. I’m not referring to those specific cases; I’m referring to cases where we have a choice, as most people living in a modern society do today. For those who have a choice, their individual choices are informing and influencing forward progress.)
