This makes me sick.
Youtube has a video of an elephant being electrocuted in the early 20th century for killing people here in the US.
Apologies ... I posted this for historical reference. It reminds me of something out of Ripley’s Beleive It Or Not. Yes, I too find this disturbing.
I think people a century ago viewed these things differently. Elephants and other wild animals at circuses and zoos were just by and large, considered wild and savage beasts.
Since then, we have learned that elephants, and many other animals, have lots of intelligence, personality, etc.
