First the bad news; the Earth is full.
Now the good news; Abundance is our future.
As both Paul Gilding and Peter Diamandis point out; we are in a difficult predicament, but we have hope for a much better future.
This isn't the future we are presently headed for. Our present path leads to a catastrophic compounding of our problems. For example; The true cost of oil.
But, things don't have to be this way.
The oil oligarchs want us to keep paying for oil, no matter how bad we don't need it. They are afraid of losing their multi-billion dollar income stream. This is literally insane behavior. They are more concerned about the survival of their companies than they are the survival of humanity.
Now for the great news:
a DOE funded company has developed a new lithium ion battery that has three times the charge capacity at half the cost of present lithium ion batteries. This is the price/performance point that some analysts consider the "holy grail" of battery characteristics required for mass commercialization in automobiles.
We don't need gas in cars built from now on.
