If people stopped getting murdered, they’d still be killed by illness, parasites, old age, accidents.
So it's okay for me to murder, because those people would die anyway? If not, then there's no point in bringing it up.
If humans stopped eating meat, millions of animals would still be killed by predators, illness, parasites, old age, accidents
Just like there's no point in saying that, unless it's intended as some kind of justification.
Why is it OK for other animals to prey on other living beings, but not humans?
In other words, why should we hold humans to a higher moral standard than lions? Are you really asking that?
If so, I can give you an answer but it seems like a ridiculous thing to ask and I'm just about positive you don't actually believe that if the standard is good enough for lions and sharks it's good enough for humans.
but not humans?
Think about it for 30 seconds and I bet you can come up with two really good reasons why there should be a different standard. If you give up, I can tell you the answer but it's really obvious. I'm confident you can come up with them if you try.
to prey on other living beings
This is also reframing the problem in a weird way. Living isn't the same as having interests, preferences, emotions, being able to suffer, etc. The majority of people who are against (unnecessarily) eating animal products don't take that position just because animals are living, but because they're sentient.
CenturyLink is absolute garbage. I rented a DSL modem from them. It got fried by lightning so they had to replace it. They sent me a modem that wasn't compatible with my service. A couple years later, I had another one get zapped. I double checked with not one but two customer service reps to make sure they were sending me a modem that worked with my service. They sent me one that wasn't compatible with my service. Then they took a few weeks to send me one that actually was compatible. When it got here, it either didn't work or something else in the wiring was messed up (probably more likely).
That last part might not have been their fault but I could have known about it 3 weeks sooner. At that point I didn't have much confidence they'd get it fixed while I still have my youth and good looks. Fortunately a smaller fiber company had just started serving the area and I was able to immediate cancel the CenturyLink service. More than 3 times faster and slightly cheaper as well. Also symmetric upload is pretty nice. CenturyLink is in for a rude awakening as competition appears in places where they previously were the only choice.
