One of the things that Ive always thought I would like to do is to develop an environmental index. Then people can measure their own environmental performance on an index as they do in other ways.

Well they do have a use, but we should never believe that any international conference is going to suddenly solve problems like the condition of the global environment.

I believe we are going to move into a situation where the more effective conferences will be smaller, more specialized, more focused, with occasional large gatherings to get the attention of the larger world.
