The Puritans managed to supress Bull and Bear baiting in Britain from the 17th Century, leading to its outlawing by 1835. WI this change of heart was extended to Big Game hunting, perhaps lagging by a few decades? So that by the time of the transport and firepower revolutions of the late 19th Century hundreds of big game hunters didn't head out to Africa and Aisa by steamship and train to slaughter prize megafauna.
Would we still have a decent amount of species such as Rhino, Asian Lion, Tiger and the like without big game hunters bagging trophies like it was going out of style?
