On and on we can go, arguing that every single plant and animal on earth would be better off if humans weren't around. And after humans, the next predator in line, and so on and so forth. eventually the entire earth would be devoid of all life except one single plant.
We are part of the food chain, get used to it.
A “food chain” doesn’t involve killing animals and leaving their bodies behind without eating a single bite of them. Nor would it make a bit of sense for one species in the food chain to cause the extinction of a species it depends on for food..
Animals know no malice, nor greed.
In many ways they are superior to man. Perhaps you should get used to this.
