You have a lot of great points here. Allow me to add a few as well.

I believe that as a society we can and must end our use of fossil fuels. I have written a letter to my representative proposing that congress have a meeting with the heads of all the major auto companies and give them a goal of replacing all internal combustion engine vehicles with either Hydrogen-Hybrids, or long range electric cars by 2045. After that ICE's would only be allowed by permit for commercial use.

I also believe that Nano-Tech if properly developed will replace manufacturing by use of petroleum-based plastics. If you can create these things at the molecular level there will be no need for the clumsy and environmentally damaging processes of today. We must push as a society for the unbridled development of Nano-Tech.
