You have labs due every week for Enviro Sci which are not too short.
Whereas you have a lot of writing to do for the Geog course.
I have not taken Anthro so couldn't say anything about that one.
If you are a better writer and don't mind writing short assignments for every class, then take GEOG. The final exam is all written so the constant writing helps you to find your voice for the issues you will be tested on.
If you prefer less writing but doing more technical tasks, go for Enviro. The labs are not hard but are time consuming.
Overall though, both courses are really interesting and I would recommend them equally.
Good luck making your choice
