Dust Bowl Causes and Consequences

The video lesson discusses the Dust Bowl of the 1930s, highlighting the severe soil erosion and desertification caused by poor agricultural practices. It explains the government's response to the crisis and the importance of soil conservation. The lesson also covers modern implications of greenhouse gases and suggests regenerative agriculture practices to restore soil health and prevent future environmental disasters.

What was a major factor that led to the Dust Bowl in the 1930s?

• Introduction of new irrigation techniques

• Mechanized plowing and removal of native grasses

• Expansion of urban areas

• Increased rainfall in the Great Plains

What were some of the socio-economic impacts of the Dust Bowl?

• Increased agricultural productivity

• Mass migration and poverty

• Improved air quality

• Rise in industrial jobs

Which conservation technique was incentivized by the government to combat soil erosion during the Dust Bowl?

• Vertical farming

• Hydroponic farming

• Crop rotation

• Aquaponics

How did the government help reduce the effects of the Dust Bowl?

• By increasing industrial emissions

• By planting millions of trees

• By banning all farming activities

• By relocating all affected populations

What is a potential consequence of current greenhouse gas levels according to the lesson?

• Stabilized weather patterns

• Increased biodiversity

• More frequent and severe Dust Bowl-like events

• Decreased global temperatures

What is a key driver of the predicted increase in Dust Bowl-like events?

• Increased urbanization

• Increased rainfall

• Reduced evaporative cooling

• Decreased industrial activity

Which practice is suggested to improve soil health and resilience?

• Frequent tilling

• Monoculture farming

• Use of synthetic fertilizers

• Planting diverse plant species

What role do microbes play in soil restoration?

• They reduce soil moisture

• They improve nutrient cycling and plant immunity

• They increase soil erosion

• They deplete soil nutrients

How can perennial ground cover benefit soil health?

• By maintaining soil moisture and feeding microbes

• By reducing microbial diversity

• By preventing plant growth

• By increasing soil erosion

What is one benefit of regenerative farming practices?

• Reduced workload for farmers

• Higher fertilizer costs

• Decreased plant immunity

• Increased pesticide use
