What I have in mind here is a romp through the world of the alternatively homed, sort of like the way that guy with the deep voice on Nature romps through 20 species an hour showing you all the exciting ways they all have adapted to their little niches. Or big niches, as the case may be.
Adaptation is the key concept here.
Maybe it's the same thrill that white Americans got watching Red Dawn . They spent years preaching freedom while snuffing it out everywhere in the world it appeared. Or, hey, I can be Kevin Costner and live in a teepee. For the price of the video I can learn to spell it tipi and impress my PC friends. Meanwhile there are a hundred men, women, and children right here in this city who are surviving in tents because they have to.
