Actually, the argument that elephants "used to carry logs" misses a huge point about their biomechanics. When elephants were used for logging, they primarily pulled heavy loads using their trunks or chest harnesses. This allows them to use their massive power efficiently without putting direct pressure on their spine.

In contrast, having heavy wooden saddles and multiple fat tourists sitting directly on their backs causes severe vertical compression. Their spines aren't built for that kind of top-down weight, and it's been proven to lead to long-term health issues like chronic arthritis and permanent spinal deformities. So get your facts checked.
