Inthesix-and-one-halfyearssincethefederalgovernmentbegancertifyingfoodas“organic,”Americanshavetakentotheideawithconsiderableenthusiasm.Saleshaveatleastdoubled,andthree-quartersofthenation’sgrocerystoresnowcarryatleastsomeorganicfood.AHarrisPollinOctoberfoundthatabout30percentofAmericansbuyorganicfoodatleastonoccasion,andmostthinkitissafer,betterfortheenvironmentandhealthier.Unit1:TextA14/382.“Peoplebelieveitmustbebetterforyouifit’sorganic,”saysPhilHoward,anassistantprofessorofcommunity,foodandagricultureatMichiganStateUniversity.3.SoIdiscoveredonarecentbooktouraroundtheUnitedStatesandCanada.Unit1:TextA15/384.
