Disaster / Destruction
The War had started over the shortage of fuel. Countries slowed to a stop. They fought for the valuable resources that they had thought would help them, but in the doing so, destroyed the countries. Earth was falling apart. People began to seek shelter in the forests, combined into villages off the maps.
The War had started in the 2049. The countries teared themselves apart just to get what little fuel was left in the world. People died everywhere. Contamination had spread, destroying miles of forests and cities, rendering them useless.
