Magnetic motors will be the energy source of the future. It is a rather new creation but imagine creating energy with the use of magnets propelling a fan. It will always spin, doesn't cause any pollution or bird killing, and doesn't cost anything to keep it powered. Check out some vids on YouTube of magnetic motors.
That 1 volcano put more CO2 and other cmpounds into the sky than all of human South America combined ever. It will cause some short term ecological, environmental, and some climate change. My arguement is that no man made creation could ever amount to this much CO2/compounds into the atmosphere at one time for it to cause this type of change. That is why cloud seeding for a grand effect is BS, as well as chemtrails. It's BS and a waist of money and energy to create these things when it takes the emount of energy as a volcano to create this type of short term change (maybe about 6 months). While humans are changing some sort if equilibrium, all it takes is 1 volcano to spew to completely change the atmosohere. A Huge volcano would do an incredible amount of damage that we could not control. The only way humans will have an effect in stopping our foot print would be to find better energy sources and slow down our own emissions. That is simply it. You never know what the earth will do either. Plus, if North America doesn't see any effects of the Volcano, you will realize just how big the atmosphere really is, and how good it is at dispersing the compounds into and out of the atmosphere, enough for us to not even notice the effects of the volcano.
