Environmental Science Undergrad Major....can i become an engineer?

<p>I'm an environmental science major minoring in biology and geography. i'm a second semester junior and since my dad owns his own civil and environmental engineering company, i'm thinking that maybe now I want to go to grad school for env. engineering. i haven't taken physics, but i have taken intro to chemistry, and calc I and II, is it possible to get into a graduate school for engineering with this?</p>
