Earth systems engineering and management is a way of looking at the entire earth and how people use it. It looks at how things like land, water, forests, and oceans are used by people and how humans can work with nature. Earth systems engineering and management helps people figure out how to use the Earth in the best way possible so that we use resources wisely and protect the environment. It is like a map - it shows us where to go and what to do so that the earth continues to be healthy and a safe place for us to live.
