The following text was presented to the 1995 conference of the International Council of Philosophical Inquiry with Children, and is reprinted here unrevised. Unfortunately the challenges of coping with global change that it discusses have still not been addressed. Some of the facts have changed—for example, China’s per capita greenhouse gas emissions have risen significantly, although they are still far below those of the United States and most other industrialized countries. But the planet is warming faster than scientists predicted twenty years ago, and little has been done to reduce greenhouse gas emissions, so the problem of climate change is even more urgent than it seemed to be when the text was first presented. Therefore my arguments about the changes we need to make to the way we live are still relevant, and it is for that reason that I have accepted the editors’ invitation to reprint the article.
