I am very interested in the field of environmental engineering. Do you know anything about it?

Yeah not to toot any horns but I know a bit about it.  Environmental engineering at its core is the practice of engineering various things of relationship to the environment such as to protect humans from environmental issues for example.

Wow, that is a very informed answer. In what ways does environmental engineering protect humans?

Well if you think of the environment not only as nature but as human created too, one scope of it includes engineering proper waste water management and air pollution control.
