Disturbing news today that genetically modified alfalfa has been approved. If you are a horse owner (like me) then of course you care if you feed alfalfa. But if you’re an urban dweller, you should care because of biotech contamination. What’s that? It is what happens in farm fields every day. Fields of crops attract pollinators and birds, who range widely, spreading seeds from one place to another, just as the wind does. Therefore, if a field of organic corn, for example, is near a field of genetically modified corn, wind, pollinators and birds can contaminate the organic field with seeds of modified corn. And what if that modified alfalfa might be growing near a wheat field that’s a source for flour you use in cooking? Read more about it.
