Many small plants have been wounded or died while I was out photographing and they were in the way of what looked like a good picture. On the other hand, I have served as part of the food chain for innumerable insects, so Mother Nature and I are probably even.
Trash laying on the ground gets moved quite frequently. That comes from taking too many pictures that would have been acceptable, if not for the trash in the scene being a distraction. Once in awhile, the trash is the subject, but I have never arranged trash just to photograph it.
Sometimes, I set up a corner or room of the house as a studio, and that means manipulating everything - moving furniture, setting up the lighting, posing the person(s), or setting up the object to be photographed. It is a lot of work. I do get good results using that technique, and enjoy the process of creating the scene.
When I just grab a camera and go out taking pictures of what I see, most often I do not get any picture worth sharing or keeping. I cannot put an exact percentage to how bad it is, but I know it is over 99% non-keepers. So, as much as I like to photograph that way, I've cut way back on it just to save on film costs and/or disk space.
