How we cite our quotes: (Chapter.Paragraph)
Quote #1
The forest to either side was a black void full of wild and ancient trees, nothing like the generic carbon-dioxide suckers that decorated the city. (7.33)
There's some hint here that the trees in the city might be genetically engineered or at least severely managed: notice how they "decorated the city," as if they were, well, decorations. Note also that the trees in the city have a purpose, like any other tool. No nature for the sake of nature here
Quote #2
Being in the city all the time made everything fake, in a way. Like the buildings and bridges held up by hoverstruts, or jumping off a rooftop with a bungee jacket on, nothing was quite real there. She was glad Shay had taken her out to the ruins. If nothing else, the mess left by the Rusties proved that things could go terribly wrong if you weren't careful. (9.49)
What's funny about this quote (besides the idea that things can go terribly wrong, that's always hilarious) is that Tally has this feeling pretty early in the book—and she still wants to go back to the city and be made pretty. We learn something about her priorities: she would rather live in a pretty, fake world right now.
Quote #3
"But it's a trick, Tally. You've only seen pretty faces your whole life. Your parents, your teachers, everyone over sixteen. But you weren't born expecting that kind of beauty in everyone, all the time. You just got programmed into thinking anything else is ugly."
"It's not programming, it's just a natural reaction." (10.68-9)
This is one constant argument between Tally and, well, the entire Smoke: are the pretties pretty because of biological reasons or for cultural reasons? If you buy Tally's argument, the pretty surgery just brings out what we naturally like; but if you buy Shay's argument, there's nothing natural about what we find pretty. Notice that each argument revolves around the idea of what's natural. (People love to say that their argument is based on nature, like "Mountain Dew was made by nature to be yummy." Be skeptical. We're pretty sure a caveman would think Mountain Dew was poison.)
Quote #4
What Tally really dreaded was running out of toilet paper. Her only roll was already half-gone, and she rationed it strictly now, counting the sheets. And every day, she smelled a little worse. (19.39)
Sometimes, the fake world has some things that we like better, like toilet paper and hot showers. Now all we need is a world where we can have toilet paper without mandatory pretty surgery. (Wait, isn't that the world we live in today?)
Quote #5
Nothing met her gaze but hills, blinding white with flowers, and the glimmering river climbing up into the mountains. It all looked so peaceful, a different world from the one that the flying machine had shattered last night. (20.36)
Here's example of Westerfeld's love of irony: Tally sees flowers and says "how nice, much better than the strange helicopter." But the flowers are actually deadly to the entire environment, and the helicopter is actually trying to save the world. (True, "saving the world" takes the form of burning large parts of it, but maybe that's Westerfeld's irony, too.)
Quote #6
"About three hundred years ago, some Rusty figured a way to engineer the species to adapt to wider conditions. She messed with the genes to make them propagate more easily." (22.43)
The orchids are probably the biggest example of people messing with the natural world—er, except for the pretty surgery. As the rangers make clear to Tally, the problem started when someone altered the flowers, and the alteration worked a little too well. Does this mean that all human alterations to the natural world are ultimately bad? Or does it just mean that some alterations get out of control?
Quote #7
Then she saw the stumps at the edges of the settlement, and gasped. "Trees...," she whispered in horror. "You cut down trees."
Shay squeezed her hand. "Only in this valley. It seems weird at first, but it's the way the pre-Rusties lived too, you know? And we're planting more on the other side of the mountain, pushing into the orchids." (24.3-4)
The Smokies have a complex relationship to the natural world: they plant new trees, but they also have to cut down old trees. It's a delicate balancing act, with "starving without technology" on one side and "destroying the world through meddling" on the other. (That sounds like an awesome circus.)
Quote #8
Life was much more intense than in the city. She bathed in a river so cold that she had to jump in screaming, and she ate food pulled from the fire hot enough to burn her tongue, which city food never did. Of course, she missed shampoo that didn't sting her eyes, and flush toilets (she'd learned to her horror what "latrines" were), and mostly medspray. (28.4)
Here's why we love Tally, because she can see both the good and the bad in a situation. So, living much closer to the natural world means that things are more interesting and intense in a good way. (Kind of like that time she rode the roller coaster with Shay—it was intense and fun to be scared.) But on the downside, there's no good shampoo and no medspray. Love that medspray!
Quote #9
The Smokies hunted, but they were like the rangers, killing only species that didn't belong in this part of the world or that had gotten out of control thanks to the Rusties' meddling. (28.6)
So the Smokies are totally good in relation to the environment, right? They hunt, but only non-native species; they cut down trees, but they plant more; and they don't even pour toxic material into the river, like normal cities. Great, but is it sustainable? What if they fix all the "Rusties' meddling"—how will they reorganize their society to maintain nature instead of changing it?
Quote #10
David lowered his voice. "Maybe they didn't want you to realize that every civilization has its weakness. There's always one thing we depend on. And if someone takes it away, all that's left is some story in a history class."
"Not us," she said. "Renewable energy, sustainable resources, a fixed population." (40.59-61)
Both the city and the Smoke seem to have okay relationships with nature in some ways: sure, the city makes everyone pretty and sure, the Smoke cuts down trees. But both believe in renewable resources and other green techniques. Still, David here reminds us: every civilization is fragile. In the long run, always bet on nature.
