The interaction, or rather non-interaction, between jeeps and elephants at the world's largest Asian elephant gathering at Minneriya National Park was respectful until it wasn't. Some drivers stopped just a little short of those elephant toes and the mothers would start shielding their clumsy offspring. A common argument is that tourism helps conservation, but it's probably not a good sign if the only thing that keeps us from annexing every last non-human habitat is a bit of petty cash.
