About 9000 years of work to change from old teosinte to maize. Select for increase in kernal size and protective layer. Kernal used to have thick layer to protect from digestion to the seeds would survive. Now has a thin membrane = would not survive in the wild. Pieces together all enzymes from animals and daffodils and bacterium. Can synthesized for certain pathways they couldn"t before. Confinement = cannot let them mingle with natural. What if wild salmon breed and waste energy on a sterile fish. Green house gases, especially co2 from fossil fuels. Check models on only natural and model with human factors. Strong human component to ghg emission and gw. Industrial countries, high density and industrial growth are factors in high emission countries.
