Interesting to note, somewhat intuitively, that the carrying capacity of a place (2.1 is population replacement value in the U.S., but those of us who live here would be wise to not accomplish that) varies according not just to number of people but also how their resources are used. It's a quick way to focus on the connections between people and environment, both with the people who actually inhabit a place and those that do not [Americans] but still use those resources (whether oil, coffee, cocaine, whatever). The political, economic, and educational climates of a place are intimately connected with population, whether beyond carrying capacity or not. You start to quickly realize how intimately people are connected with their environments. I started trying to think in that way, i.e. that I am not just in my own ecosystem when I am out backpacking, climbing, or otherwise outdoors. Every second of every day, every little thing I do has an impact. On the one hand, I could easily get overwhelmed and depressed by that idea. On the other, it's an immensely powerful feeling of connection with everything. I think that one major problem, especially in technologically-obsessed societies, is that loss of connection. You can be a conservationist, even, and still be disconnected from your environment (of course the origins of conservation are anthropocentric, but anyway…). But as soon as you get that realization back, you start to see your own significance. It's basically the position of deep ecology, but not exactly. All of this is still connected with backpacking.
All hail Isaac Asimov.
I would choose windmills and solar panels over smokestacks and dams and mounaintop removal any day.
