From Fred White, Nottingham, UK
You report that ingestion of microplastics by mice changes their behaviour in the face of a deadly corn snake. After being given food contaminated with plastic, they failed to treat the snake as a threat(10 May, p 38). Would it be too cynical to speculate that the lack of concern over the past 40 years by humans in the face of obvious climate and ecological collapse may be due to exposure to plastics?
