Review Questions

• How did industrial growth during Period 8 impact air quality in urban areas?
  • Industrial growth during Period 8 significantly worsened air quality in urban areas due to increased emissions from factories and vehicles. The rapid expansion of industries resulted in higher concentrations of pollutants like sulfur dioxide and particulate matter. This deterioration led to health problems for residents, sparking public demand for stricter regulations to address these environmental concerns.
• Evaluate the effectiveness of the Clean Air Act of 1970 in addressing air quality issues.
  • The Clean Air Act of 1970 was instrumental in setting national standards for air quality, establishing the framework for regulating pollutants. Over the years, it led to significant reductions in harmful emissions from industries and vehicles. However, while it has improved overall air quality, challenges remain with ongoing pollution sources and emerging environmental issues such as climate change, necessitating continued revisions and enforcement.
• Discuss the relationship between public health initiatives and air quality improvements during Period 8.
  • During Period 8, there was a strong correlation between public health initiatives and improvements in air quality. As awareness grew about the health impacts of pollution, particularly respiratory illnesses like asthma, community organizations and government bodies pushed for cleaner air policies. The establishment of agencies like the EPA enabled more effective regulation and enforcement of air quality standards, leading to healthier environments and better public health outcomes. This connection highlights the critical role that informed citizen activism played in shaping environmental policy.
