The "Four Horsemen of the Apocalypse" ride whenever competition for resources and territory reaches a critical threshold. And there are those among us who welcome them as harbingers to the subsequent Second Coming of Christ.

Thus, they see no need to reverse population overgrowth in a proactive manner.
The Islamic State, an outgrowth of Wahhabi Muslim fundamentalism, is an answer to their prayers. At last, a definite sign of the anti-Christ. As for the Islamists, this Christian fundamentalist thrust is what they most desire to justify their Jihad. Behold, neither group is spiritually awakened enough to fully realize that God and Allah are the One and the same Supreme Being.
