Detailed explanation-1: -The biggest causes for the dust bowl were poverty that led to poor agricultural techniques, extremely high temperatures, long periods of drought and wind erosion. Some people also blame federal land policies as a contributing factor.
Detailed explanation-2: -The 1930s drought that turned the southern American Great Plains into what we now call the Dust Bowl was an example of a climate pattern-driven by sea-surface temperatures in the Atlantic and Pacific-that had always been typical of the region. Now, warming may make such droughts more frequent and more intense.
Detailed explanation-3: -Of course, during severe dust storms, more dust can get into the lungs. Dust irritates the lungs and can trigger allergic reactions, as well as asthma attacks. In people who already have these problems these attacks can be serious and cause breathing problems. Dust can cause coughing, wheezing and runny noses.
