The problem at hand already rises at semantics; Most "nature-lovers" aren't nature-lovers at all. They like artificiality; A kind of trimmed, romanticised disney version of nature, which has been designed and sold as a product catering to human conceptions of idyllicism, pseudo-purity and naïveté, traits which people have falsely called "Pure" and "Untouched".
When confronted with real nature, they prefer to look away, or rather, blame mankind for it's viciousness. The idea that their dear nature, what they subconsciously see as more pure and good than humanity, is far more vile than our society is anathema to them. It destroys their last imagined "safe spot."
I am very honest about this, nature, at least the term as it is used when people talk about a nature-artificiality dichotomy, is evil. Not evil as in "wilfully malevolent" - nature doesn't have a will - but evil as in cruel, petty, pointless and undesirable.
