I guess it's one of those things, if there's enough money to be made in it, everything else gets swept under the rug.
There's plenty of deaths and injuries related to theme park rides, but it's never stopped them from making faster, more dangerous rides - or even closing the ones that've caused the accidents.
Still, I reckon I'd pay to see them. Perhaps dinosaurs are even stupider than expected and ...they just stay where they're supposed to? Every time I've been to the zoo all the animals are sleeping anyway.
