I think it would be a good idea to cancel or decrease tarrifs on agriculture product from the third world. I think it would only benefit us in many ways. First of all when the we have shortage of specific grain we would have source from other country would meet our requirements. Also if its cheaper for your consumers then why not!
Imposing import tariffs not only makes it more difficult for people in third world countries to sell their agricultural products to developed nations and thereby reduce poverty in the third world, it also stifles competition. This allows domestic producers to set their prices artificially high and without fear of foreign competition, resulting in higher priced food for consumers.
