I worry about our air. No, not because of normal pollution. That is a given and we have been worrying about it for a long time. What I wonder about is all the signals and radio waves travelling through the air. How can they all fit? Is there space for birds to continue to fly? Can they still navigate? What do the waves do to your head or brain as the waves pass through or even around.
In the past fifty years, the number of radio waves have increased umpteen thousands of times. What are they doing to us? We have just added a heap more with satellite navigation systems in our cars, well maybe yours, not mine since I am poor and a sat nav would look silly in a twenty three year old car.
The eccentric, but grudgingly respected my medicos, Sydney brain surgeon Charlie Teo thinks mobile phones are doing our heads in, well our brains, possibly causing cancerous tumours.
I had a friend who started suffering bad headaches and he suspected his mobile phone use could be the cause. He switched to handsfree and the headaches disappeared. Just one anecdote but I am sure there are many more out there.
How many more radio waves can fit in the air? Surely at some point, even if they don't do us physical harm, they are all going to get tangled up and stop working.
