A couple of general examples why environmental groups may have concerns, none specific to the Tesla story in particular, but I know have happened elsewhere: - The location has a unique/endangered flora or fauna and building in the specific location would be a significant blow to those species. - Ground water issues when a large area is paved, roofed or otherwise covered. - Noise/light pollution affecting nearby residential and/or environmental areas. - Increased traffic though connecting roads causing related issues. It's as far as I see never about the specific industry building in the place, but rather the local effects of building in the area that need to be addressed.
