Its also because big ass herbivores are actually really dangerous.
Sharks don't actually like the taste of humans because we're a little too lean. So they won't actively hunt you unless they're starving. There's only really one reason why a shark is out to get you. There's many reasons a herbivore will mess you up.
A big herbivore will fk you up because he's having a bad day and you got too close. Or its mating season and everyone is potential competition.
Or they mistook you for a predator cause of their poor eyesight.
Or a bird flew away nearby and one of them got startled and now you're in a path of a stampede.
There was a 82 year old man who had to pee and couldn't hold it in, so he went to a train track to do it. While he was pissing, a cow from the air crushed him. His death certificate literally says "Death by a flying cow".
It turned out that cows were crossing a track and the train hit one of the cows full speed, so it was sent flying right towards the man. He ended up passing away.
I literally walked into my grandparents' garden one day and found a cow just hanging out. No one believed me when I went to tell them until they heard it moo. Turns out it had managed to break the fence at a local field and was just roaming.
