In democracy the people should decide. Scientist can be experts in the field, but definitely that can explain things in laymans terms and the public can make a decision. If scientist were to make a decision, the we should not call this a democracy.
Agree with you that we should not sign this agreement in a hurry and pawn our country for our children and grand-children to pay for it. If our forefathers fought and gave us freedom, let us at least not give slavery to our next generation.
