(p. D4) To the Editor:
The idea that ancient man had fewer tumors because he lived in a less polluted atmosphere (“Unearthing Prehistoric Tumors, and Debate,” Dec. 28) can be held only by those who have limited experience living in a preindustrial way. Try cooking over an open fire burning half-rotten wood, or sitting in a cave warming yourself with a peat or dung fire, and you will know what pollution really is.
