2. What is the traditional theory?Anthropogenic land-use leading to soil degradation and vegetation loss
3. Why did deserts grow in the past?Scientists used to think people caused deserts by overgrazing, cutting trees, and farming too much. New studies say big storms and floods also made the land dry.
4. How do extreme weather events affect deserts?Big rains can cause flash floods that wash away topsoil and plants, making the land dry faster than slow changes from less rain.
