Volunteer Work related to Environmental Engineering

Hi my name is Erlyn Garcia and I'm currently 16. I have been thinking about my future and a plan for my life since it wont be too soon when I must make a decision for a major. And I have been thinking about environmental engineering for some time. So my question is; what kind of volunteer work should I be looking into to get a small grasp as to what it may feel or look like when in the future I hopefully become an environmental engineering if I choose that for myself.
