See - if humans weren't the lazy, filthy litterers they are, archeology wouldn't exist. This doesn't comfort me a whole lot as I'm picking wrappers and beer cans out of the salal, but it amuses the hell out of me when people natter on about how ancient cultures lived in "harmony with the land." Only by dint of having too small a population density to have an overwhelmingly negative impact on the environment!
On a different tangent, this could get interesting for the literalists:
In the past four days alone, Oxford's classicists have used it to make a series of astonishing discoveries, including writing by Sophocles, Euripides, Hesiod and other literary giants of the ancient world, lost for millennia. They even believe they are likely to find lost Christian gospels, the originals of which were written around the time of the earliest books of the New Testament. [emphasis mine]
