Desertification has a massive effect on the environment and the world. It can be argued that early Saharan pastoralists changed the ecology of fear in the area, which in turn enhanced scrubland at the expense of grasslands in some places, which in turn enhanced albedo and dust production and accelerated the termination of the African Humid Period. Also, because desert plants don't follow the same seasonal cycles of other areas, they tend not to release allergy-causing pollen into the air at the same rate.
