Moral of the story, if you can and want to, pursue the field that will allow you to become the most qualified. Get a degree that will not hold you back. No degree is worthless, however, an engineering degree holds weight over a BA. Would you rather hire an environmental studies major or an environmental engineering major?
I am biased, I am studying civil and environmental engineering at Cal. But being qualified and having no restraints is what pushed me to pursue engineering.
