Geezuz, nothin' like a "my resource, your resource" argument to bring out the best in people.

We put in dams, locks, and crappy ladders, then
b!tch because opportunistic critters are using them as dining establishments.

We poison the sea water with PCB's, then complain because there aren't any natural predators to thin out the sea lions.

We dump tens of thousands of hatchery fish into our rivers that incidentally ALL lead to the salt, which is the sea lion's natural habitat, then b!tch because they eat them. Hello, McFly!!!
They're hungry!!

In my dark, distant past, I've had sea lions take thousands of dollars out of my pocket in one day and never once thought I should shoot one, and there are people that post hero shots twice a week here that suggest there aren't enough fish for them to catch.
