Mainly because of location on the planet and the fact that the desert areas are so far from any water. For most deserts on earth location is a big factor. This is because certain weather phenomena occur to create a dry climate at certain latitudes on the globe. The details surrounding this are explained below. But just think of it this way... why do glaciers form? Their location is the main factor, as parts of the globe are better suited, weather and climate wise, to support glacier formation. The same thing is true with deserts, but may be less obvious.
As far as deserts increasing in size, yes this is true. According to one site I found, it said that 20,000 square miles per year are becoming deserts (http://www.didyouknow.cd/deserts.htm). Desertification is mainly thought to be a problem of people. In particular, too many people. Overgrazing of lands, over-cultivating land, and destruction of forest land for development are all human related activities that impact the increase in desertification.

Since it is a statement, it has no answer
