Environmental social science is a field of study that looks at the relationship between people, their environment, and how it affects their lives. It looks at how people impact the environment (such as how pollution affects the air we breathe), how the environment influences how people live (such as how air pollution can make people sick), and how we can work together to protect and care for the environment. Environmental social science also examines how different policies, activities, and lifestyles can affect the environment.
