Passage Summary: The author says we shouldn't listen to famous people who tell us to be green, because those famous people have huge carbon footprints themselves.

Conclusion: Criticism of middle-class environmental impact should be dismissed.

Reasoning: The celebrities who criticize middle-class lifestyles are hypocrites because their own lifestyles are even more environmentally damaging.

Analysis: This argument commits a classic 'ad hominem' fallacy, specifically the 'tu quoque' or appeal to hypocrisy. The author attacks the character and behavior of the critics rather than addressing the actual substance of the environmental criticism. Even if a movie star is a hypocrite, their claim that certain lifestyles damage the environment could still be factually true. Look for an answer choice that highlights this focus on the person's character instead of the validity of their argument.
