Query: Pretty good overview of environmental science

I took a class which used this textbook at the University of California, Santa Barbara, which was co-taught by one of the authors, Ed Keller. This is an introductory book that provides a decent overview of the problems we are currently facing in regard to the environment, what we can do to solve those problems, and other opportunities that our environment can give us.
