It is no accident that the Abrahamic religions all began in a region of the Middle East, where nature was at its most bleak and hostile, and therefore only human culture was seen as benign. Making human culture, which in those days and places meant, paternal authoritarian culture, all powerful.

The other reason why religious people do not care about the environment, is simply because, they don't care, full stop. Religion is essentially a selfish pursuit, 'my' relationship with god, 'my' church, 'my' salvation, 'my' immortality and 'my' spiritual life, it therefore only attracts selfish and shallow people, there may be exceptions but not generally.
