Truth be told

Because the constant killing is parted between different species. Also most of those animals are bred to be eaten, they don't just go extinct.

And are we counting all the bugs we run over and spiders we squash and flies we swat? Because the OP is making an unfair comparison.

How would we, no one counts them.
But altogether 60 billion of livestock are killed annually, if you're curious.
I think it's just been shortened, what they meant was animals being actively slaughtered.

While not all due to human intervention, up to dozens of species go extinct everyday

Yeah, and most of the stuff we wear doesn't even require the animals to die or get hurt.
