They over use fertilizers‚ which contain chemicals such as petroleum‚ that make the soil economically useless and dangerous to living organisms. Pesticides‚ which are also very harmful in the farming world and overused as well‚ cause much damage to crops everywhere. In a chapter from a book‚ The Long Emergency‚ Kunstler argues that we as Americans have been “eating” our sources of natural gas by the use of petroleum-based herbicides and pesticides and fertilizers made out of natural gases and if we

Climate misconception played a large role in the creation of the Dust Bowl as well. The misconceptions
