I'm a landowner, and we shoot my land a lot for doves. I've never been a stickler about guests picking up every hull. Most try to, but when they are left behind inadvertently, I have found that they deteriorate much faster than most think they would. In a couple years of lying in the sun they plastic begins to fade in color and become very brittle, a sure sign of ultraviolet breakdown of the plastic.
I have occasionally found the brass case head of hulls my Grandaddy shot while hunting this land. They are precious to me, and I pause and think that he may have shot into a covey right where I'm standing many years ago. Those were, of course, paper hulls.
I'm not a slob, and I care for my land and try to be a good steward of it for my time here, but I don't get all jacked up over a few hulls or wads that eventually break down due to UV anyway.
JMO, YMMV.
