As a society, I feel like we are generally distanced from death, and even the circle of life. And I know that we've all had loved ones pass away. BUT we are a relatively long-lived species, so even the death of a loved one (at least for most of us) is not a frequent occurrence. I would hazard a guess that the majority of us, partly due to our modern cookie-cutter neighborhood lifestyle, are sort of ultra-sensitized to death.
In these ethical debates we often hear that posters want "the death to be quick, so the animal doesn't suffer." Unfortunately, the normal (not smacked by a pellet) death of animals is rarely that. Pdogs for example, number one pest species I take out. Their normal predators (and what also kills many many many more than I can with pellets on the couple days a month that I have time to go shoot them): hawks, coyotes, badgers. You think the hawke that swoops down to snag a pdog off the top of it's burrow thinks to make sure it kills its dinner quickly as it sinks its talons into whatever part of the critter it can? Heck no, it grabs it however it can, a closed talon with any part of a pdog inside it is a full belly, whether the talon closed on the back end of the animal or pierced the vitals. That same hawke will also rip that still alive prairie dog into bit size chunks, slowly and methodically. The coyote also doesn't care if the pdog is alive or not as it rips and crunches. Badgers? probably the most traumatizing of all for a pdog. Badgers literally dig them out. Imagine being a pdog, dead-ended into a long tunnel, knowing and hearing something with huge claws and bigger teeth and an even bigger attitude digging it's way towards you, slowly enlarging your burrow enough for his fat arse, and his appetite, to make it to you. Nothing you can do but wait. And again, once that badger gets to you, he ain't gonna ever so carefully and delicately, politely snip your spinal cord so the calories your corpes provides to him aren't so painfully ripped from your bones.
Okay, okay, yeah graphic. But also what actually happens all day every day before, during, and after we've left the pdog fields to go home and chill out in our air conditioned houses.
I grew up on a ranch. The small critters mentioned above are short-lived, but even with cattle, death is never very far. Mother cow will get infection from prolapse, or foot rot, or snake bite, or get caught in a barbwire fence or a piece of wire on their foot that cripples them. Any and all of those often result in having to put her down. Baby calf will break its neck when it hits the ground at birth, still alive, but paralyzed. Or coyotes ate the baby as it was still being born and now what's left of the calf is dead inside and momma has systemic infection from the decay that set in before we found her. Gotta put em down.
I trapped a couple winters to sell the fur. Lots of death there too. We lived out on this ranch, miles from town. All kinds of critters would wander into the yard acting funky, our typical conclusion was rabies. So, I'd shoot em and carefully dispose of the corpse (my dad couldn't ever hit anything so I was the designated shooter). Usually skunks, possums, and coons. Had wild hogs that would RUIN a hay meadow, rooting and digging holes. So we eradicated them as well. Lots of death. But that's nature and the real-world that exists where there isn't asphalt and curbs and manicured lawns.
All that sounds morbid and graphic, but when you've been extensively exposed to death (and I don't mean going out on Saturday's and shooting a couple pest birds for the farmers) it becomes normal. That understanding that one animal has to die for another to survive becomes more real.
So, when I go pesting on my family's ranch or any of the other properties where I've been asked to come shoot pdogs or ground squirrels or pigeons or euro doves or starlings, I'm there to kill em cuz that's what I've been asked to do. Yes it's fun, but it's also fulfilling a need. Those ranchers need the #s of pest animals reduced. There's no ethics at play. It's not a human or even a game animal. I'm not going to eat it. I usually don't even feel the need to get up close and see the corpse. So, yes I'll take long hale marys, and not even bat an eye about it. I sleep just fine at night.
