If you take a look a around the cosmodrome, you can't see any wildlife other than the birds that fly in the sky, or the weird flying animals in the skies above Venus. I think, there should be animals to make the environments more lifelike, that you can interact with, hunt, or chase around for absolutely no reason. That's just my opinion.

Well, animals don't go where they know they'll be in danger unless they absolutely must go there for some reason. Wild animals largely stay out of cities, at least bigger animals do. With all the alien activity and what not I'm not surprised that we don't see much wildlife, but that would be a different story if the cosmodrome was much, much larger
