Nah, it's humans. Humans get farted on the most. Walking on foot? You're walking through farts. Using public transportation? Farts. Going inside any building open to the public? You've guessed it, farts.
The more crowded a place, the higher the concentration of farts.
Please remember that no matter where you go, someone will fart in your general direction.
Horses themselves fart the most of any animal. They hardly even digest the grass they eat it's more of a fermentation process. If you've been around them more than a few minutes they fucking fart almost constantly lmao
Depends on what we qualify as an animal and what we qualify as a fart. Would a plant’s waste gas, oxygen, be considered a fart? Sloths experience at least 10 continuous hours of oxygen production. Photosynthetic jellyfish deal with constant, full body internal farting.
Even if we only believe animals can fart, that leaves coral with an order of magnitude more farts, and siphonophores with a dozen orders of magnitude more than that.
Horses didn't evolve to carry such weight on their backs, or to be kept and controlled by people riding them. It can't feel great.
Oh and in order to be ridden, horses need to be 'broken in' first, as in literally have their will broken and tamed to the point where they accept people climbing on them and directing them to move, without the horse biting, bucking of bolting.
It's really fucked up if you think about it. Animal abuse is so normalised that most will argue against horse riding being abusive to horses. No animal naturally wants to be broken and used by humans.
In my teens I farted on my best friends little brother. Made it natural. He was taking his turn playing a video game and sitting on the floor. I was standing talking to his brother. I leaned back a touch and let it rip on his shoulder.
His reaction was priceless. Horror and "aahhh I felt my shoulder vibrate!"
