“We have met the enemy and he is us.” Walt Kelly, Pogo comics I have been writing about resistance to toxic chemicals. And though I have plenty of posts on other stuff, I have shied away from cancer, even though one of the biggest problems with treating cancer is resistance. Yet it is difficult to […]


Reposted from Whole Terrain with permission; and from Island Press Field Notes We are a chemically-addicted society.
