This number is the NRDC (National Resource Defense Council) telemarketing number. Since I am a member of NRDC I emailed them from their web site and requested that if this number is associated with them to please drop me from the call list. They answered my email and were very nice about it since I explained that I was deaf and don't answer voice calls. The have flagged my membership record and noted that I was not to be called. Since then I have not received any more calls. If you are a member of NRDC and a BIOGEMS defender you can email them at
