Agriculture chemicals and gmo crops are no friend to wildlife. They spray stuff on beans that is killing off the song birds. it can even be a health threat for anyone that tries go in those bean fields after the spraying is done. We used to have wet waterways in every field and corn was full of foxtail. When I ran a newspaper company, I found letters talking about the impassable boggy long grass conditions, that was Iowa, to people that were planing to load the wagons and head west. The plains are suppose to be wet. Tiles have wiped out the wet areas and there is nothing in the corn except corn. i feel sorry for migrating hawks, because for mile after many miles there is nothing here for them to eat. Sooner or later all life forms are negatively affected by development, agriculture , chemical pollution, and equipment uses and transportation advantage. Before I had some financial set backs that prevented me from having enough cash on hand for a down payment to buy some land, that I figured would pay for itself with a clover/alfalfa crop and honey bee acres, i made a decision that it would be a longbow and ground hunting only hunting area. If this sport is to continue, it needs restrictions. Farming is set up so that the global elite control how things get done and they don't care at all about real wildlife issues. They do however, all agree that we should be paying taxes to the global warming bank in England, that started out because the coming ice age was imminent. The 'green' advocates have done nothing for the environment. I fear that the imbalances and damage in some areas is irreversible.
