I guess I am being vague, because my argument distills down to simple optimism vs. pessimism. I can't argue what is not known. We don't know what tomorrow's energy sources will look like. We don't know how to sustain two, five or ten times the population, let alone the exponential growth we've witnessed. Of course something has to give, and it will. Fossil fuels are unique, sure. And of course they are limited. But imagine how limited people felt in the 1700s when their entire energy and food supply was simply the sun and arable land. I bet that felt rather absolute to them too. I mean, it's the sun. It's pretty fundamental and unchanging. What else could there be? Surely we can do the math on how much farmland there is to work and calculate possible yields and determine the maximum number of humans the planet can sustain. And what should be done with that number? Yet centuries later we have shattered those limitations many times over, doubling and doubling and doubling the population again. I don't mean to belabour the point, maybe we will transcend our current limitations (I think we will), or maybe we won't. But even if we don't, let resource scarcity cull and control population instead of policy.

The crux of the astrophysicist's argument lies in thermodynamics. Given the economic track we're on, the demand for energy will equal the entire output of the sun. Not merely the output of the sun that the earth's surface can capture, but 360 degrees' worth of electromagnetic radiation at 100% conversion efficiency. I too recently thought that humanity probably overcome whatever problems the universe throws. But I don't see how humanity plans to "transcend" the laws of thermodynamics. The least far fetched idea I can think of is antimatter. But handling a substance that volatile somehow seems to me like a very bad idea. You seem to be appealing to this notion that "There's so much about the universe we still don't know. What the future looks like is beyond our wildest imaginations." http://chem.tufts.edu/answersinscience/relativityofwrong.htm http://chem.tufts.edu/answersinscience/relativityofwrong.htm Above is Isaac Asimov's essay The Relativity of Wrong. In a nutshell, an English teacher had expressed disapproval at Asimov's arrogance when he "had expressed a certain gladness at living in a century in which we finally got the basis of the universe straight." To which Asimov responded "[that the teacher] may be imagining that because all theories are wrong, the earth may be thought spherical now, but cubical next century, and a hollow icosahedron the next, and a doughnut shape the one after." Humanity doesn't know everything. And maybe we never will. But at this point, we're pretty confident that we've gotten down the basics . I.e. Relativity may have replaced Newtonian Physics, but Newtonian Physics wasn't outright invalidated for everyday velocities. By and large, our scientific body of knowledge is logically monotonic. We'll augment our models, we'll refine our models, but it's unlikely we'll ever say, "Newtonian physics is, and always has been dead wrong. We have to start physics from scratch."

> But even if we don't, let resource scarcity cull and control population instead of policy. And this is a different issue altogether, concerning ethics. As I said before, I think birth control policy is the better of 2 evils. The other evil being warfare resulting from abject poverty. Such policies would prevent a lot of needless pain and suffering. I'd rather live in happier world with less people than in a sadder world with lots of people. It's not like those unborn will mind, because they won't exist. But maybe you think the parents will mind, or believe in the efficacy of natural selection. Our stances remind me of The Giver/Gathering Blue.
