For example, based on a world population annual growth rate of 1.3%, the world population would reach a density of one person per square meter of land in 780 years. That blows my mind. In ten human lifespans we will have overrun the planet.
This guy lays out a dire situation for our energy consumption, and a gross misrepresentation by the media and the government about our ability to sustain our energy consumption. Not a pleasant message. Based on the current predictions we hit peak oil production in 2004, and it’s all downhill from there.
My takeaway is that it’s a race between the exponential growth rates in technology and the exponential consumption of oil. If we can successful use the energy in oil to develop new sources of energy, then we live. It sounds like the new solar technology starts to become commercially available in five to ten years, with who knows how long to switch over. So we may have a shot.

]]>The Cornell team searched for some independent measure of increased television viewing. In recent years, leading behavioral economists such as Caroline Hoxby and Steven Levitt* have used weather or geography to test assumptions about behavior. Bureau of Labor Statistics studies have found that when it rains or snows, television viewing by young children rises. So Waldman studied precipitation records for California, Oregon, and Washington state, which, because of climate and geography, experience big swings in precipitation levels both year-by-year and county-by-county. He found what appears to be a dramatic relationship between television viewing and autism onset. In counties or years when rain and snow were unusually high, and hence it is assumed children spent a lot of time watching television, autism rates shot up; in places or years of low precipitation, autism rates were low.
It’s always impossible to judge the quality of research from a mainstream media report, and there’s a lot here that’s suspect. But four hours of tv a day for kids on average? That’s damn scary.
