Its called Animal Husbandry, and as far as we can tell only us humans ever achieved it. Industrial production of animals, far beyond the numbers animals can achieve in the wild.
Take pigs for example. There are roughly 6 million wild pigs in the continental US: https://www.nationalgeographic.com/animals/article/wild-hogs-swine-pigs-feral-us-disease-crops#:~:text=Today, around six million feral,thriving in nearly any environment.
However there are roughly 72 million farm pigs:
United States hog inventory down 2%
USDA National Agricultural Statistics Service Information. NASS publications cover a wide range of subjects, from traditional crops, such as corn and wheat, to specialties, such as mushrooms and flowers; from calves born to hogs slaughtered; from agricultural prices to land in farms. The agency...www.nass.usda.gov
Now I may just be one of those egg-head liberals that reads and can do math, but I'm fairly sure 72 is higher number than 6. Almost as if the industrial production of an animal creates greater numbers of than animal than you would find in the wild.
As to the cowspiracy that cows contribute to global warming...yeah. Its real. 14.5% of global greenhouse gas emmisons comes from cow burps/farts:

Cow burps are a major contributor to climate change — can scientists change that?
Livestock production—primarily cows—produce 14.5 percent of global greenhouse gas emissions. The majority of that is in the form of methane, a potent greenhouse gas that is a natural byproduct of how some livestock process food. But as Christopher Booker reports, scientists are hoping that small...www.pbs.org

Cows and Climate Change
Cattle are the No. 1 agricultural source of greenhouse gasses worldwide. One cow belches 220 pounds of methane yearly. Fortunately, UC Davis has solutions.www.ucdavis.edu

Farmers, scientists seek solutions to global warming caused by cows
The world's one billion+ cows are responsible for about 40% of global methane emissions - a significant contributor to global warming. Some climate-smart farmers and scientists are tackling the problem from, ahem, both ends.www.edf.org
But again, this is egg-head stuff by scientists and readers. Its not real world stuff, you know?
There was an estimated 45 million buffalo in the US before Europeans came over. Also, there are 100,000 elephants today while there was an estimated 26 million 500 years ago. Guess what elephants emit? Methane. To act like there couldn't have been similar amounts of animals producing methane at dangerous levels hundreds/thousands/millions of years back is just not true. If animals emitting methane is so dangerous, we would've had an environmental collapse a long time ago.The issue is specifically ruminants, such as cattle. Most animals only produce a small ammount of methane in their intestines, which they fart out occasionally. Ruminants produce much, much larger quantities of methane in one of their stomachs, which they burp out continuously. Their shit also gives off a lot of methane as it decomposes.
Because of intensive farming, there are far, far more ruminants (especially cattle) in many areas than the ecosystem could naturally support. This also means they can't rely on grazing for food and need to be fed grain, which causes them to produce more methane.
Again, that is bad science used as propaganda. The 14.5% number is from GLOBAL numbers. In the US for example, beef accounts for 2% of all US GHG emissions. Also, what does it matter the percent? I'm guessing before human interventions, animals probably contributed like 90% (or something like that) to GHG emissions, thus we've come so far in curbing animal emissions if you wanna use that metric. The question is if it's too much and if it is, how big of a problem it is. Regardless of those answers, it's a rather tiny problem (if it is one) in comparison to other GHG emitting issues there are. We also literally need cattle to survive. Cattle are such an important food source because they can eat all the food we can't eat and turn it into food we can eat plus the eat all that food on land that we can't use to grow food on anyway.
