Human and Natural Disasters
Human activities are largely involved in the formation of some natural disasters, while not involved in the formation of some others.
As we all know, it is obvious that humans have nothing to do with the formation of volcano eruptions or earthquakes. But some other disasters, for instance, sandstorms, are related to human activities. Overgrazing and overcutting ruin vegetation, in turn causing desertification. When sands meet a windstorm, a sandstorm comes into being. Another instance is acid rain. Waste gas produced in industry activities, mostly in thermal powering, goes up to the clouds. It then blends with the water vapors. As a result, the rain from the clouds becomes acid, doing a lot of harm to humans, animals, plants, etc.
