World Conditions, End Times, Leading to Christ's Return.

Revelation 11 18 And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
‣ Bible(KJV)

The Earth is over-populated, and is being over-polluted. The poverty striken, and economicaly disadvantaged, mostly live in the heavily populated cities. The unregulated for profits intersts continually pollute the Earth.
This graph shows estimates of the World population had jumped from about 1B in 1800 to after the year 2000 around 7B an increase of almost 600%. It is projected to rise another 5B in less than hundred years, to a total of around 12B, by the year 2100.
