Dhumavati Meets a Geometric Solid

A year or two before Al Gore’s An Inconvenient Truth was released, I went to a panel discussion and film (alas, I cannot remember the title of the film) about global climate change.  One of the speakers was a Nepalese attorney who was working on a case in the World Court that sought to address the impact of various corporate practices on the Himalayan snow cap.

One of the things this man said continues to resonate with me:  “Why is it,” he asked, “that Americans are always turning on lights in the day time?  Do you ever think about how much energy we could save and dangerous, climate-changing emissions we could stop, if we just relied on day light during the day instead of adding unnecessary electric lights?”
