Not to sound callous, but for those of us who fish and hunt, such illnesses and deaths are the canaries in the coal mines of our world. We already know that you cannot drain the wetlands, plow under the last native grasses, and pour anhydrous ammonia along channelized creeks without dire consequences to, at first, fish and wildlife, and then, naturally, to us all. We hunters and fishers already know this: you cannot destroy your environmental capital without racking up huge and ugly debts. We are the witnesses. We are the Cassandras of our time.
