Anyone living near or otherwise caring about the Chesapeake has long known the impact that fertilizers have on it and on other bodies of water: fertilizers = plant growth = algae blooms. This is true whether the fertilizers were sprayed on crops with an intent to fertilize or if they are runoff from concentrated animal feeding operations. Now that algae limited access to drinking water in a city of over 500,000 (instead of merely limiting the production of crabs and fish as it does here in Maryland) maybe there will be more than requested voluntary controls. Then again, maybe not.
Great article sent to me today by Prof. Jane Wolfson: Neil deGrasse Tyson is getting into the issue of GMO's. He says that there are problems such as monopolies and nonperennial seed production, but that these are not problems intrinsically linked to GMO's. If you want to fight those problems, great: you should. That doesn't mean you should be opposed to all GMO's, though!
