C)Will the genetically modified salmon not grow as well in the wild as they do in inland facilities and how much money will be lost if this occurs?
Answer is B---Will the genetically modified salmon introduce modified genes into the wild salmon population and what will be the impact on the ecosystem?
----Biggest ethical concerned scientists should research before releasing the genetically modified salmon into the wild . This is true because critics like Anne Kapuscinski among others who is a professor of sustainability science and chair of the Environmental Studies Program at Dartmouth College have explained their concerns over introducing modified salmon in to the wild , They are of the opinion that if the genetically modified fish got into waters with a population of the wild, THEY may eventually compete with their wild counterparts pushing them out or altering their habitat or ecosystem even though some other scientists are in the opinion that physical barriers which will be introduced can prevent that from happening.
the radiations that are used to treat cancers are of the gamma type. primarily emitted from cobalt-60 (a radioactive isotope). and it is more controlled than other radiation exposures. i.e. solar radiation which is not controlled.
hope that this helps.
