You sound like the ecology professor from UBC that gave a speech I listened to on the radio last night. His thesis was very much along those lines, determining the ecological footprint of mankind and whether or not it is sustainable over the long term. He determined that the average human being on the planet requires about 2.8 hectares of land to produce all the resources (food, water, raw materials, energy, etc) needed to sustain themselves in our current lifestyle, though there is quite a disparity between the rich countries like Canada, USA, Australia, and western Europe (averaging between 8-12 hectares per capita) and the Third World (as low as 1 hectare per capita). However the total land mass on the planet divided by the total population only works out to about 2-2.1 hectares per person. Therefore he concludes we are overconsuming the available resources on the planet, and if there is not a shift in the cultural lifestyle expectations of the Earth's population, that we will inevitably cause a severe ecological shock, much like your high-school biology example.
I'd never heard the argument put that way before. It was quite compelling. And depressing .

Economically and politically, population growth is good, and so is immigration. It's more people--more people that can produce and consume more goods. What's wrong with that?
Environmentally, population growth can be okay if the children are not Earth-raping corporate whores, of course.
