IMHO the PO DOOM message needs a little tweaking.
Having KCan present it is a good start, however

.
I like the idea of how, in the little video segment, she presents it as a great challenge to humanity to innovate and solve a big problem. That bit is good really. The bum you out first part needs a bit more sugar!
I can remember seeing a documentary about commercials and their influence on people. They had a test group watching a commercial from a utility and each person had a little box with a knob on it. As they watched the commercial, they would turn it one way if they felt good about what they were seeing. Conversely , if they were bummed by it they would turn it the other way. Later, a computer would correlate the responses to the script and images of the piece. The parts that really bummed people out were edited and or removed. These were terms like pollution.
So that's my take on getting sustainability through the public's thick head. Present it as a challenge that can make things better.
