Bring reusable items and pack out what you brought in! Many people who would never normally drop litter, for some reason, seem to think that it is acceptable to leave the remnants of a camping adventure in the midst of the desert, where they could remain for years. UAE desert animals, such as the endangered Arabian oryx, can become fatally trapped or injured while foraging for food.
In short: Whatever you do, do not leave anything at your campsite that wasn’t there before.
