I agree with and endorse this.
I don't think they are aiming high enough though. There isn't much talk, yet, about moving industry off-planet, orbital habitats, mining the asteroids, and colonizing the moon.
True, we you're never going to see a major reduction of population on-planet no matter how many people manage to migrate off-planet.
But by getting people out there, we can start bringing in new resources. And we get some of the eggs out of our basket; just in case.
But I have already wandered off topic. Technology is the Only Hope. Everything else leads to catastrophic (re)adjustment at some point in the future. With more than 7,000,000,000 people on the planet today (Wasn't it just 6 billion a mere 20 years or so ago?), how can it be otherwise?
Organic farming isn't going to save us. High-yield, high nutrition, fast growing crops that have been modified to thrive in less than optimal growing conditions; that may save us from starvation.
Power Generation - with the possible exception of people who make their living from coal, how can anybody argue that burning coal (or even natural gas) is how we should go about generating electricity? Even if you're still ignorant enough to be anti-nuclear power, there are other alternatives that are just waiting to be used/developed (you know, technology?). Solar, Geo, Hydro all made possible by technology.
We are not very far from a time where all that we will need to live and thrive are power and mass. From that point on, all that will really old us back is our own greed and short-sighted selfishness. (Far-sighted selfishness, on the other hand, can actually be a good thing.)
I guess that will be enough ranting for one night. The article got me fired up I guess. I have known for years that technology, and the infrastructure if makes possible, are the sole reason we have the highest standard of living world wide, than any previous time in history.
Okay NOW I stop.
