Jungle covers up most of the ancient Angkor temples and other ancient sites made by mankind. If all ancient buildings still would be around, then we would live on a junkyard. Life goes on after a failed culture has sunken into jungle. Ancient ruins are like bones and remainders of death ancestors - we leave them in peace and go on in our lives. Ta Prohm temple is one of many temples were nature was quiet successful in cleaning up - until mankind discovered the temporary market value for the tourist industry and uncovered all remains for profit making. Jungle can keep generations alive. Stones and temple ruins only can cause expenses for generations. Nothing else.
