I should have said "our back yards" then? Seriously though, I've been working outdoors since the 70's, and have watched first-hand how the aerosol spraying affected the weather here starting over a decade ago, and then I watched as the whole concept of aerosol spraying was filled with disinformation until 'chemtrails' was made one of the flagship symbols of the conspiracy theorists. The topic was being discredited even as I monitored it's real effects on the weather around me, so I understand the feeling of powerlessness I guess. Now, though, awareness might spread since it's no a longer mythical thing- all the smart scientists at Harvard say it is real.
