Our world has places so abnormal, that they make alien societies seem ordinary.Following are some remarkable locations in which people once lived (and some still do).

1. Izu Islands:

Off the coast of Japan lies a series of volcanic islands. Due to the air being full of sulphur, they were evacuated as recently as 2000. However, citizens moved back, despite having to wear gas masks for most of their day. This is mainly due to a pension provided by scientists studying the debilitating effects of the environment. When the alien zombie virus hits Earth, these will probably be the only people left alive.
