drugs or environment

My list of programs to study next autumn is basicly down to 2; pharmacy and environmental engineering. I've check out the pharmacy program and will probably be able to check out the other one in Umeå when i'm visiting Chris. Pharmacy is more chemestry, environmental engineering is more math. They are both going to be much harder then the program i'm studying now (which really is very realxing) and it's probably going to be easy to get job, at least as an engineer. One of the reasons i want to study the engineer program is that i'm much more intrested in "saving the environment" then making drugs to people. It's a hard choice and i have about a month left to decide.
