If the oysters, scallops lobsters are losing life to CO2 levels have we gone too far on our global thermostat? Should we look at something non toxic rather than toxic? Would this method to shade the planet at the mesosphere above the Ozone layer interfere with cooling efforts from using non toxic oxygen on the clouds to remove heat? How will it help the Ozone layer which really protects life? Do the particles really levitate up there and for how long? Isn’t it just more of the same thinking used lower down or is it more appropriate and logical? What is the most important thing when you have an emergency in a large room and need to leave-the exits, we need heat to exit our atmosphere and so how is this accomplished?
