AFTER the existence of sufficient intelligence to be able to ask such a Question, a facetious Answer might be, "If you think living things shouldn't, then why not start with yourself?" After all, most living things have an ingrained "drive to survive" --Evolution basically weeded out all the life-forms that didn't have that!
THE ROCK DOES NOT HAVE ANY IOTA OF VOLITION. Even a microbe has enough volition such that after detecting a nearby food-particle, it tends to move to engulf it. (While this is certainly more of a stimulus/response thing than any sort of "will" getting exercised, I'm melding the two things here under the generic label of "volition", simply because it can be difficult to tell when stimulus/response ends and "will" begins,
as classically pointed out here.) Your Question basically asks why your volition is superior to the volition of other entities that also have it. Prior to the existence of sufficient intelligence to be able to ask such a Question, the Answer appears to be, "Nature doesn't care; anything that can possibly happen is allowed to happen." In terms of Evolution, there is The Law of the Jungle, basically "might makes right". As previously mentioned, living things cannot survive without obtaining resources from outside themselves. Often those resources are found in other living things....
AFTER the existence of sufficient intelligence to be able to ask such a Question, we note that humans
claim to have a greater degree of "will" than all the other life-forms on Earth, and humans have traditionally used that excuse to conclude that their volition is superior to the volition of other living things. In general, most humans are equated with other humans in that way, and therefore the volition of one is not usually considered to be superior to the volition of another. The main exception is unborn humans, which provably have no more volition than ordinary animals. (We know this because we can test infant humans easily, and they are basically stimulus/response machines --which means less-developed unborn humans are also basically stimulus/response machines.)
A "POPULAR" PRESENTATION DOESN'T MAKE THE SITUATION LESS REAL. The plight of bees has been getting well-documented in appropriate scientific circles for several years now.
PERHAPS YOU SHOULD ACTUALLY PRESENT SOME FALLACIES, instead of exposing your ignorance.
