Just as with other great words, the word environment means different things. You might say that a cave woman twenty thousand years ago sweeping out the cave was improving the environment. Many people improving the environment think only in terms of the air they breathe in their hometown and the water in the aquifer under their hometown. My guess is very few are thinking centuries ahead or thousand of years ahead, but that's what we have to do.
