You're right, I articulated my position extremely poorly. The needs of people and civilization should often win out over the needs of wildlife. But almost always in a way that sacrifices only wildlife within a confined spatial region and almost never in a way that threatens an entire species.
If there are species living around the globe that might not be able to continue their current role in the global ecosystem in a world where 5G is pervasive, then we should not allow the use of 5G in the vast majority of the world. The consequences, for humans, via trophic cascade or whatever, would be extremely uncertain. Are the benefits of 5G really compelling enough to brave them? Certainly they are not compelling enough to me.
