Hey ho, how ya doing?  I'm an environmental engineer!  I protect humanity from the adverse effects of the outside environment.
Oh wow what does you job entail?
I design structures that are able to shield people from things like rain and hail.  I also an concerned with energy preservation and protection of natural resources.
Oh dang that sounds quite important. thats cool.
I also cross with public health workers and collborate with them on issues like waterborne diseases.
Seems like a very demanding and important job
Yeah buts its fun, and varied as well so I'm never bored.  Waste water management, recycling, waste disposal and cycle insurance.  It's all good.
Wow thats a lot of things you have to deal with.
Never all at once, heh.  I'm just glad I'm out in the suburbs.  FI I were in the city, it would be nonstop evaluation of proposed construction for their environmental impact.  That would get boring.
