| What will the Earth look like in 500 years? | ||
| One massive city | ||
| Full of flying cars | ||
| Devoid of man | ||
| Idyllic biodomes in harmony with nature | ||
| An industrial cesspool | ||
| Much like today, but with more people | ||
| Similar to the 1500s | ||
| An asteroid-shattered rock | ||
| We don't have that long. In 2012 it'll all end | ||
| I have no idea | ||
| Who cares? We'll all be gone! | ||
