Droughts lasted in the US during the early 1930s. This lead to failed rains an increase in temperature year after year. Winds blew with ferocious speed. Even the ordinary Storms became black blizzards. As the entire landscape had been ploughed over continuosly, soil turned over by the tractors and vegetation uprooted, the grass cover that held the soil disappeared. The broken soil turned into dust that could be blown even by the mild making the whole region a dust bowl. As a result people were blinded and choked, cattle was suffocated to death, fence buried under the sand and the surfaces of rivers were coated till the fish died. Dead bodies of birds and animals were scattered all over the landscape. Tractors and machines were clogged with dust. These were the damages that were beyond repair. This made the Americans realise that they had to respect the ecological conditions of each region.
