This comic features a philosopher giving a speech at what turns out to be an environmentalist conference. He argues that he is not saying we should destroy the Earth, but rather that if we do, it won't be "sad" in any objective sense, since the concept of sadness exists only in human minds. The caption below reads: "Philosophers are no longer allowed at environmentalist conferences."

The joke highlights the tension between philosophical reasoning and practical activism. The philosopher is making a technically valid point rooted in moral anti-realism or nihilism -- that emotions like sadness are subjective human constructs and do not exist independently in nature. However, this kind of detached, academic reasoning is profoundly unhelpful and even counterproductive at an environmentalist conference, where the entire motivation for action is rooted in the emotional and moral weight of ecological destruction. The comic satirizes how philosophy's pursuit of logical precision can render it tone-deaf in contexts that call for moral urgency.
