This world was once inhabited by a highly industrial society. Little was done when pollution began to damage the ecosystem, and when the vast forests that once covered the southern continent were destroyed to make room for more growth, the resulting greenhouse effect raised average temperatures by more than 10 degrees over a 200-year period.
