More than half of U.S. adults polled for a recent PEW study indicated they viewed trade agreements between the United States and other countries positively. The U.S. Grains Council says the study results are good news for agriculture, which relies on global sales to help promote profitability. The PEW study found that 51 percent of adults included in the poll thought trade agreements were positive for the United States. Since the end of World War II, the United States has negotiated agreements with 20 countries, which is an important but small collection when compared to the more than 260 trade agreements in place around the world, according to the Grains Council.
