Differences between women and men.

[Excited Penguin]

Then I think you're wrong. Certainly, when talking about the differences between men and women one talks about a society rather than an environment.

In social sciences, environment often tends to mean anything aside from genetics. So social would be considered environmental.

Right, guess I must've forgotten about that.

Just goes to prove my point that using social instead of environmental is better in some circumstances, so as to avoid confusion.
