why was it important to establish the clean air act?\no to reduce the need to study the effects of dirty air on human health\no to determine ways to reduce the number of premature deaths per year\no to create a regulation that makes any activities that pollute the air illegal\no to raise the cost of air purification techniques to ensure the efficiency of removing air pollution
Answer
Brief Explanations:
The Clean Air Act aimed to protect public health and the environment. It sought to reduce premature - deaths caused by air pollution by regulating air - polluting activities. Studying the effects of dirty air on human health was still important, and the act was not about raising the cost of air purification techniques. It made polluting activities illegal to control air pollution and reduce premature deaths.
Answer:
to determine ways to reduce the number of premature deaths per year
