Have you ever driven your car around while staring at the dashboard in anticipation of the odometer rolling over a landmark reading? I have.... perhaps because most of my vehicles have been near the 200,000 km mark. Well, this week the human race rolled over the 7,000,000,000 mark!

I find this to be incredibly interesting... and I hope at least one or two of you do as well. This number says a lot about us as a species. The rate at which we are increasing impacts us economically, socially, and politically. Habitable land and essential resources are decreasing while our population is steadily increasing. Judging by how we as humans still don't seem to care about our rapid consumption of non-renewable resources and out destruction of our environment I suspect that most of you out there don't really understand the urgency to change the way we live.... either as part of a group of 7 billion or as individuals living in your little corner of the planet.

I am currently reflecting on the fact that I was the 4,248,434,931th person on Earth when I was born and the 78,719,717,138th persons to have lived since history began.
