As an environmental sciences student, a person studies how technology impacts the environment. In addition, a focus is put on learning about how humans affect the environment and how to solve issues and threats towards the environment due to human activities.

A PhD is a highly advanced degree that helps graduates become experts within a field. Earning this degree may help students be better qualified for their chosen careers as well as any other professional pursuits they may have.
