Final answer:
The US National Academy of Sciences, Engineering, and Medicine (NASEM) is mainly involved with developing a thorough inventory of USDA data to help quantify economic losses that may be incurred by farmers as a result of their non-GMO crops being contaminated by GMOs.
Step-by-step explanation:
The group mainly involved with developing a thorough inventory of USDA data to help quantify economic losses that may be incurred by farmers as a result of their non-GMO crops being contaminated by GMOs is the US National Academy of Sciences, Engineering, and Medicine (NASEM). In their GE Crop Report, NASEM reviewed more than 900 research articles and concluded that there is no substantiated evidence of a difference in risks to human health between genetically engineered (GE) crops and conventionally bred crops, nor did they find conclusive cause-and-effect evidence of environmental problems from GE crops.
