2. Environmental Science

While the effects of human lifestyles are damaging the environment, doctors must address the converse relationship and how it relates to patient health. In schools such as Upper Iowa University and the University of Southern California, students use mathematics, chemistry, physics, biology, and earth science to examine pollution, nuclear waste, and global warming. As one of the best pre-med majors, environmental science will prepare pre-med students to address how the environment is shifting the health concerns of the population.
