This book is based on them. They are supplemented by a few boxes of facts and figures to highlight a particular issue or stress a point. This compilation is presented in the hope that it will further clarify how serious things are. It is intended as a prelude to the Epilogue, which stresses the duty to hope and looks forward to what can be done to avoid environmental catastrophe. There are many hundreds, thousands, of successful experiments. DS UN Environment Document Repository RD Sep 17, 2026
