Is there human interference in the desert ? if so what type?

There are many types of pollution in the desert that occurs, including mining waste, radioactive dump sights, and urban sewage. All of the pollution comes from the desert cities. They also cause pollution like leakage from toxic waste dumps which particulate matter in the air. Many people pollute in the desert because it's seen as a place where nothing value exists. Some people even haul toxic garbage to the desert for illegal dumping. The people also interfere in the desert because they build different things like military targets and test ranges that could kill the plants and animals in the desert. They build mobile homes or ATV's in the desert which kills the animals in order to build. The affects of the human interference causes many animals and plants to become endangered in the desert. Some of the endangered species are Pronghorn which is part of the antelope family, Caracal which is a member of the cat family and the Fennec Fox. Proghorn is endangered because hunters kill them for sport and food. The Caracal is endangered because they are usually killed by farmers for eating the farmer's livestock. The Fennec Fox is endangered because they are hunted for their fur. Yes there is a fear of climate change for the Sahara desert because there has been an increase of growth in plants and greens. Animals such as camels, scorpions, and the addax antelopes are going back to the desert because of this increase in growth.
