The author, Rebecca McNutt, explores the complex relationship between people and pollution in her book "Smog City." She suggests that while pollution is generally seen as negative, it may possess both beneficial and harmful aspects, similar to human nature. The comparison raises questions about societal attitudes toward those who are different or considered problematic, emphasizing that discarding these individuals would mean losing valuable lives.

McNutt challenges the reader to consider whether our efforts to eliminate pollution would continue if it were personified, encouraging us to reflect on our environmental actions. She prompts a deeper understanding of pollution, advocating for a thoughtful approach rather than a purely negating one, highlighting the nuanced positions we hold regarding both humans and pollution itself.
