I totally said that two years ago Apo. I'm like the Greek Sybil. Or something. re; Angkor expansion:

I had read couple of years ago when I was creating the contents for the Angkor hood here that there are alot more temples and that satelite imagery is showing it was even larger than that, with a population running as much as 1 million. But that's not what I'm saying I said, it's that this large population caused massive enviromental damage dooming it's own city.

Excerpt from site: ""Angkor was extensive enough, and the agricultural exploitation intensive enough, to have created a number of very serious environmental problems," he said. "

I said (two years ago)

"A city loses, a jungle triumphs
With the recent discovery of many temple complex areas and individual temples surrounding the heart of Angkor through satellite imagery, scientists are gaining a new perspective into why the residents of Angkor fled and perhaps the loss of the city/empire itself. The region Angkor is in is surrounded by a dense jungle environment, and a population exceeding 1 million would mean the landscape had to be altered greatly and an untold expanse of forests mown down to accommodate farming requirements. All this points to one hard truth - desolation from landslides, drought and fire. It is widely accepted now that this combined with war against neighboring empires foretold a certain death to the society and civilization of Angkor.
