ABC broadcasts a special at 9 p.m. Tuesday that forecasts a bleak - make that no - future for civilization by the next century unless we somehow curb population growth, resource depletion and climate change.
In "Earth 2100," ABC says correspondent Bob Woodruff talks with a series of experts to draw up what is admittedly a worst-case scenario, given current trends.
Among those interviewed is John Holdren, science advisor to President Obama. According to ABC, he tells Woodruff: "If we continue on the business as usual trajectory, there will be a tipping point that we cannot avert. We will indeed drive the car over the cliff."
