Currently there are several imported fruits and vegetables grown using pesticides banned in the U.S. because U.S. corporations find that it is cheaper to grow and/or import crops from countries with lax or non-existent environmental laws. If a foreign nation allows the use of pesticides on crops that are banned in the United States, should it be illegal to import a crop grown with it or should market forces always rule the day (the most product for the cheapest price)?
