In this specialization, you will explore how many public health outcomes are directly influenced by human contact with the environment. The four courses in this series will introduce you to the environmental health sciences (EHS) discipline; you’ll examine the hazards of air pollution, water pollution, solid and hazardous waste, radon, and noise; identify the major challenges posed by climate change and unsustainable practices; and use risk assessment to evaluate the health of population, advocate for environmental justice, and improve global health.
