Environmental engineering is very import job for the planet. It is a passion for helping the world such as cleaning the ocean, making recycling systems, and even developing air pollution equipment.
A specific example of environmental engineering is the project that the American Academy of Environmental Engineers and they have been trying to develop a way to track endangered species.
I found this engineering field to be most interesting because it's engineers helping to make the planet a better place for us and i find that very heroic.
