Have we learned enough since this TED video of tech investor John Doerr was created in March, 2007? Will there be a point when governments, businesses, and individuals wake up and take the strong, palpable measures that the vast majority of climate scientists indicate are needed?
Wal-mart is used in the TED video/talk as an example of a business thinking in "green". It seems that John Doerr does not see the picture fully about the entire Wal-mart product and energy life cycle, but his point about the impact and visibility of Wal-mart's changes carries significant weight.
That said, the depth of cuts needed in greenhouse gas production, according to most experts, are far deeper than the goals of most organizations and governments. And structurally, the nature of most businesses and individuals may push the great majority into continuing energy-wasteful patterns that could lead the planet down a path to harm.
Possibly, just possibly, we may get clever enough to produce enough energy in a clean way (wind, photovoltaic, geothermal, etc) worldwide so that the climate change does not break out and become a runaway disaster. But the level of change today on our planet, more than a year after this video was made, is still far too small.
This is like watching a good cliff-hanger movie - but the movie in this case is our entire planet. At risk is our perceived golden dream of a comfortable future with a large house, jumping into a car whenever we want to go somewhere (or flying if that is too far away). Food is also flown in to the developed world from all over the planet, and the many toys (child and adult) come mostly from China.
Until we each learn to see that the luxurious life is the life that is simplified, that is built on strong relationships, that is based on internal maturity rather than external needs being met, until that change occurs, the changes we make in our ways of life may not be enough.
