Word like "misanthropic", but referring to Nature
Solution 1:
No such word in broad usage occurs to me. If I wanted that sentence to be easily understood, I would write nature-hating, tree-hating or hippie-punching, depending on what tone I wanted to set. If I wanted that sentence to provide a satisfying experience for the pretentious classicists in the audience, I would coin misogaeic.
Solution 2:
In the example provided, "environmentally unfriendly" would be an apt play on words.
