Have you tried a posting on Usenet? There are the following groups that may be suitable:

uk.environment
uk.environment.conservation
uk.politics.environment

If you don't have access to Usenet I'll post something for you. Just give me some idea of what you want to say.

Never been on Usenet so I guess I have no access, I'll formulate something tonight.

Any other target groups that I should be thinknig about? who else is concerned about quarrying, the environment, archaeology, etc.?
