I actually had a similar problem with my public health courses, so I called AMCAS. They basically told me that you're free to classify your courses however you want (i.e. biostatistics for math rather than health or whatever) but that they'll change it if they think you misassigned it. If you list it as one of the BCPM and they don't change it, it will probably count.
I agree though, I don't think the Environment class will count.
