For instance, and it’s interesting, it takes more than 2,400 gallons of water to produce one pound of meat! Think of that! It means that each vegetarian saves at least a thousand gallons of water per day, depending upon how much meat they formerly ate. Which means, if one hundred million people did that each day it would amount to a hundred billion gallons of water saved! So, the numbers are just mind-boggling. What would a hundred billion gallons of water even look like? I have no idea…
I think I can tell you what saving all that water would look like. Where I live, it would look like a very minor (probably undetectable) amount of additional water flowing into the White River, thence to the Mississippi, thence into the Gulf of Mexico.
It would look like farm ponds bulldozed over because where I live, we get about four feet of rain per year. With nothing taking water out, they would just overflow, then go into local creeks, then into the White River, then into the Mississippi, then into the Gulf of Mexico.
No use for those ponds if nothing is drinking water from them. Out to sea with the water!
But that’s probably not the way it would be. Nature abhors a vacuum, and the grasslands will inevitably fill up with wild ruminants very much like cattle unless the government maintains a crew of shooters to keep them from it. Remember, most of the U.S. grasslands won’t grow anything people can eat. Just grass. That’s about 1/3 of the land in the U.S. So what will fill in? Well, when Columbus landed, there were just about the same number of buffalo in the U.S. as there are now cattle. So, maybe buffalo, elk, antelope, deer, on the otherwise abandoned grasslands? They drink water too.
But if the government hunters kill off all the wild ruminants and keep them killed out, then yes, we would have a little more water flowing into the Gulf of Mexico…maybe. As hoofed animals, cattle aid in water retention in the grasslands. So maybe there would be no gain at all in the water flowing out to sea.
So, if we got rid of all the cattle, we would probably see no difference at all in the water availability in the places that need it. And what does anybody propose anyway? That our excess rainfall be captured and sent to the Sahel or somewhere?
But I will grant one thing. In my judgment, it is a great waste to have government subsidized irrigation projects in California drylands so people there won’t have to ship milk in from places where it actually rains.
