Let me guess, predators have been exterminated already in those areas? Wolf, bear, lynx -- driven into extinction in many areas
Where I live we have bear, coyotes, bobcats, and dogs all of which kill deer/moose.
We also have fast-moving vehicles and very long cold winters, both of which kill a lot of deer/moose.
We also have humans who can hunt by permit only, and may kill one deer a year.
It's tough to be a deer (or a moose) round here...
I would somewhat agree with hunting for food. However... it is historically a thing of privileged classes, therefore "sports" and hardly a neccessity to put food on the table.
In the UK maybe. Where I live in the US, it's the opposite way around. Hunting is more of a lower class occupation, and everyone either keeps the food to eat, or donates it to a food bank.
