You'd be surprised how much enviromentalism borrows heavily from the judeo-christian ideology.
From it's romantic view of nature which is similar to the garden of even but without humans, their worship of Earth as a deity, the occasional reference to Al Gore as an Oracle and even carbon credits and proposed CO2 taxes which is quite similar to how the church operated with something called a sin tax.
The comparison between the two, however, ends when enviromentalism uses thuggish tactics towards skeptics(granted that there was the inquisition, but this is the 21st century, not the dak ages), guilts people and scares the hell out of them with proficies of forthcoming doom(there is armaggedon, but once again, this is the 21st century, not the dark ages).
The church is not socialist, it is a private entity that provides charitable services, they operate with a tax exemption clause that is applied to all religions.
"Helping the poor" is generally Socialism's de facto excuse to do anything but...
But I'm getting off-topic...
One staggering hipocrisy that I would lke to point out is how some in Portugal like to complain about religion, but some reason, are not against religious holidays, which is curious considering that about 80% of all portuguese holidays are religious ones.
