P4B thats a good idea but its going to cost the government a shitload of cash and as far as recuping the money through a food tax on exports well i dont think that will fly mainly because it will cost jobs because if you put a heavy tax on exports of food other countries will go looking for food elswhere.There is no solution because oil will keep going up in prices because of demand.Until we start demanding a different form of transportation then nothing will change.
