Cool, sounds like a double-cause/effect essay.
Well, I don't know what to call it, exactly. But anyway, just write an attention-grabbing intro, and then tell the reader that the essay is about two things. "This essay is intended to show the effect of (thing #1) on (whatever it effects) and (thing #2) on (whatever it effects). It should be easy!
The only tough part is the thesis statement, which should probably go at the end of that first para, and which should say something meaningful about the relationships among the two sets of causes and effects, and the implications with regard to... anything interesting! Make it cool and meaningful.
Good luck! Does that help???
