>Beef cattle use nearly 60% of the world’s agricultural land but account for less than 2% of global calories and 5% of global protein consumed.

Sure... We're going to create 5 more planets to provide all the pasture needed to feed the world with your food of the future.

Yeah, why not? Humanity seriously needs to develop the technology required for space stations dedicated to farming and livestock, space industry in general. Much better than wasting human talent and potential on adtech nonsense, that's for sure.

That idea seems to show up occasionally in science fiction which has quite the uncanny ability to predict the future so I'm just gonna assume it's going to happen at some point.

It is sad to see this line repeated on a forum that in general prefers science to soundbites.

Reality is a lot more complicated. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6616661/

If it's complicated you should probably explain. Your link doesn't disprove the parent -- it compares different water and land use of various cattle raising methods.

Over 60% of cropland in the US goes towards raising beef, a food which makes up a very low percent of the calories in an average person's diet.

I provide a study from the National Library of Medicine. This study provides a nuanced view of the topic here, and provides a lot of data.

If you did read the scientific study I linked to, then you would now know that land that "food animals" occupy is often not at all suited for other forms of agriculture.

You would also know that various food animals can be fed and raised on waste from other agricultural processes that humans could not consume.

That is why I stated "It is more complicated than what the original soundbite line portrayed it as.

Does that help?

How much of a cow's diet do you believe comes from resources that would not be otherwise useful to humans?

Cattle farming uses most of the water in the west. https://www.vox.com/the-highlight/23655640/colorado-river-wa...

Your image of cattle grazing out on the range is out of touch with reality. Nearly all beef consumed in America starts with diverting water that could go towards directly feeding humans

We just consume too much beef

Most of the feed that cattle get on feedlots is waste from ethanol and biofuel production, aka distillers grains. We feed cattle very little fresh grain so all of the statistics about cropland use are extremely misleading. Several industries use that grain one after the other.

That feed along with the fresh hay is fed to cows at the end of their life to fatten them up for human consumption. Notice how the article you linked says 200 million acres of cropland used for beef and 325 million overall versus 900 million acres of total farmland? Most of the difference is marginal pasture that can’t grow anything for human consumption. We don’t fertilize or water it, it’s just grassland that grow by itself where we raise cows before sending them to feedlots. Without that cropland going to distillers and cows, over 60% of our farmland would be completely useless. Not only that but most of our cropland isn’t very useful either - 95% of the corn we grow is inedible dent corn. It’s one of the cheapest commodities on the planet that’s only worth growing as a last resort.

We make this tradeoff because those 600 million acres of otherwise unusable farmland are far more resilient than our cropland so we have a huge backup of calories incase of massive crop failure.

That's a good point, I know in Australia, NZ, the Uk/Wales etc, sheep and cattle graze in farmland that would not be easy to reshape (e.g. terraced) for agriculture. So that otherwise "useless" farmland ends up being useful.

Source: rock climbing one day and finding sheep grazing on plush grass in an otherwise inaccessible location. Apparently it's well known, and locals will climb up to look for said lost sheep.

Their feed and hay occupy land and use water that could be used more efficiently to directly feed humans.

My uncle was a cattle rancher in Arizona, on "marginal" land that didn't grow food for humans. It didn't grow enough for his cows either. We would leave out bales of alfalfa to keep the cows healthy. Alfalfa is grown in those big irrigated circles you've surely seen while flying.

Most beef consumed in the US comes from feedlots. Over 70% of "grass-fed" beef sold in the US is imported.

We just consume way too much beef
