What does it mean to be "Environmentally Literate?"

A person who is Environmentally Literate is able to look at most situations and topics with an awareness and understanding of how the environment fits in.   When making decisions of their own, and evaluating the decisions of others, they're able to weigh the impact those decisions will have on the various aspects of the environment.  Being Environmentally Literate isn't just simply caring about the environment, though that's a good start.  It requires a person to be educated and informed, so their efforts aren't misplaced, and so they can lead others in preserving and protecting the environment.
