Are Caravaner's Conservationists?

I like to think that I share my love of the great outdoors with fellow members and that we as campers care for the environment.  Most sites I stay on seem to be oasis of calm and wildlife prospers because we are there and treat the area with respect.  A few discussions recently seem to show that members have scant regard for the natural flora and fauna, I am sure that is incorrect and it is the little things that we do or don't do that have a big impact as mankind is the most destructive animal on the planet?
