There are some amendments which are / will be considered this week or soon that will aid GMO labeling efforts and small farmers. Below are a list of the amendments (provided by Farm To Consumer Defense League). Please consider calling your Senators on these.
Also yesterday I sent out a google newsletter listing the facebook page of some of the major grocer chains. If Congress can't or won't act to require GMO labeling, maybe we consumers can get the corporate stores to do it for us. Whole Foods has committed to requiring GMO labeling by 2018 (it takes time to ramp up). This can be done, and has been before when Krogers was one of the first to require rBHT dairy products be labeled even with the threat of lawsuits from suppliers.
Ask your favorite store to require GMO labeling
