For all medical doctors, engineers, researchers and (e)inventors I have a book recommendation: Cross Currents by researcher, medical doctor Robert O. Becker.
Dr Becker early understood that a human being is an electromagnetic entity. The first edition of this book was written in 1990 and now it is more actual than ever.
For example: The healing of wounds and bones is based on electric currents inside of us. Our cells communicate with electricity. Our body functions and rhythms (including circadian) are based on changes in natural(!) electromagnetic fields. Becker also showed how acupuncture and many other alternative treatments work.
Artificial electromagnetic fields and mobile devices/basestations/powerlines distort this communication inside of us. Being concerned about life on earth, Becker tried to inform military and industry about safer technologies (without immediate success).
In case you have difficulties in getting the 'Cross Currents' book, try Robert O. Becker and Gary Selden’s earlier book Body Electric in eBook, PDF-format.
Update 18th June 2009: Talking about environment: The chapter called Maxwell's Hammer is worth reading. I hope that soon the environmental discussion will focus on the bombardment of ionosphere + abnormal growth/changes caused by microwaves (before it is too late). Hopefully Green Party(ies) and Greenpeace will finally get it: climate change is NOT only about increased CO2-levels. Constantly growing powerline grid and dense base station network has an effect on weather, nature and ionosphere.. Not to mention the risky HAARP installation in Alaska :-( (Update 26th July 2009: The following document of professor Ulrich Warnke describes those mechanisms of harm in detail : "Bees, Birds and Mankind - Destroying Nature by Electrosmog")
Becker was twice nominated for Nobel prize in medicine. For very good reasons.
It would be great to hear your comments about Becker’s books.
