We've had an estimated 30-60 million bison in the US, now we have 100+ million cows.

And cattle and bison differ in their grazing behavior and ecological impact, making a direct environmental comparison unfair due to their distinct roles in shaping ecosystems.

It's our cattle and farming methods that are wiping out all wildlife.

The 2022 Living Planet Report found that vertebrate wildlife populations have plummeted by an average of almost 70% since 1970, with agriculture and fishing being the primary drivers of this decline.

Our global food system is the primary driver of biodiversity loss

The way we eat could lead to habitat loss for 17,000 species by 2050

Two recent studies underscore the danger the meat production system poses for biodiversity.

Biodiversity conservation: The key is reducing meat consumption

Just to compare cattle mass to cattle mass.

> We've had an estimated 30-60 million bison in the US, now we have 100+ million cows.

The US has always had < 50 million adult cows (milk or beef), the difference is yearling calves.

The bison estimates likely didn't include calves either .. and have a lot of bounce in any case.

There were 89.3 million head of cattle and calves on U.S. farms as of Jan. 1, 2023,

https://www.nass.usda.gov/Newsroom/2023/01-31-2023.php

* Of the 89.3 million head inventory, all cows and heifers that have calved totaled 38.3 million.

* There are 28.9 million beef cows in the United States as of Jan. 1, 2023, down 4% from last year.

* The number of milk cows in the United States increased to 9.40 million.

* U.S. calf crop was estimated at 34.5 million head, down 2% from 2021.

* All cattle on feed were at 14.2 million head, down 4% from 2022

As pointed out by olddustytrail .. that's the US.

Elsewhere meat consumption can save the planet by decreasing hoove heavy ferals that aren't managed at all - eg: Australia where camels, donkeys, goats, and cleanskin cattle are all introduced animals run wild that can be rounded up and trucked out every year in a never ending game of trying to keep their numbers in check and stop them over taxing the environment.

Kangaroos are native but savagely boom | bust - when the wet years hit numbers spike and if the population isn't culled the following years see the ground littered with dead as water resources contract.

Well, when you say "our" you mean your own. Our local cattle graze on the machair.

But that's not the argument you originally made. You were saying it's impossible to raise grazing animals without being environmentally unfriendly. That is the part I dispute.

Hardly.

Animal farming became unsustainable due to its massive environmental footprint, including deforestation, habitat destruction, pollution, and excessive resource consumption, which collectively strain the Earth's capacity to support such practices.

We cannot feed the population with the same version of American or European diets - we'd need 5+ Earths to do it.

Beef has an energy efficiency of about 2%. This means that for every 100 kilocalories you feed a cow, you only get 2 kilocalories of beef back.

We've deforested large swaths of habitable earth to make space for animal farming - it uses 80% of our agricultural lands.

Deforestation is the leading driver of habitat loss ... and the leading driver of it is animal agriculture.

https://ourworldindata.org/drivers-of-deforestation

We've destroyed so many habitats and poisoned so much that we're driving almost a million species to extinction.

"A 2017 University of Oxford study titled Grazed and Confused accepted that managed grazing systems could sequester some carbon back into the soil. It added, however, that this was only around 20-60 percent of the emissions that the cattle produced in the first place. What’s more, after a few years soil reaches carbon equilibrium, meaning it cannot sequester any more."

Animal agriculture takes up an area as large as both Americas, yet provides only 18% of calories and 37% of proteins.

If we were to reforest that area, we could sequester so much carbon that we would reverse the warming.

Feeding 10 billion people by 2050 within planetary limits may be achievable

A global shift towards healthy and more plant-based diets, halving food loss and waste, and improving farming practices and technologies are required to feed 10 billion people sustainably by 2050, a new study finds.
