" Every science that the environmental historian approaches presents him or her with a language, and that language is filled, like any of the world’s languages, with metaphors, figures of speech, hidden structures, even world-views — in short, it is filled with culture. The environmental historian wants to learn that language … and use it to improve his understanding of the human past. But as a historian, trained in the modes of thought common to the humanities, where language itself is an important object of analysis, he must insist that the words of the scientists not go unexamined. They are themselves worthy of attention as expressions of culture. "
