Our next session will debate the issue of pollution and clean environment on the outcome of the Golf of the Pacific ecological catastrophe. The speaker is sure that this is (also) a Masonic topic. Some eyebrows will rise. There is no Masonic symbolism present but the author argues that more then ever we face today, in the world, the always present debate on quantum salis. It this a political debate? Where passes the divide between urbe et orbe? And between earth and cosmos?
